Replacing crabs on a VAZ 2115 - Sarterminal.ru

To begin with, we will describe the location and functional purpose of the so-called “crab” on the VAZ 2114. “Crab” is the front suspension beam mounting bracket.
The resemblance to a marine arthropod is given by four mounting holes for bolts. Faulty crabs are a common problem with Lada Samara of the first and second generations. The brackets are made of a rather fragile material - silumin, so during prolonged use or increased load on the chassis they simply collapse. The destruction can be complete or partial (when one of the four fastenings comes off).

Even if one of the four sides is torn off, it is unsafe to continue to operate the car: the increased load on the bracket will lead to the threads from the remaining fasteners being subsequently torn off.

It happens that a car enthusiast notices that the fastening of the VAZ 2114 crabs has just begun to collapse - in this case, a crack appears on the bracket area. The crack can be welded, but this will be a temporary measure that will slightly extend the service life of the fastener.

If a breakdown occurs while driving, this can lead to loss of control over the car, so it is better to periodically check the integrity of the brackets of their platforms: “crabs” do not fail instantly, this is preceded by long-term wear with all visual manifestations (unless, of course, it is not This is a manufacturing defect).

IMPORTANT! The main danger of increased wear of the front suspension beam mount is that the breakdown has no “symptoms”: the driver can lose control at one moment, even if there were no prerequisites for this.

Crab VAZ 2114 signs of malfunction Replacing the crab on a VAZ 2115 with your own hands - step-by-step instructions

A fairly common “sore” of many models of the VAZ family is a faulty or damaged front suspension extension fastener, or in common parlance, a “crab”. The crab holds the front suspension brace located under the front bumper.

Often, the destruction or malfunction of the crab occurs due to the fragility of the product itself, which is made of silumin or another aluminum-based alloy. The crab usually crashes on high rocks, a curb, or other elevation that the driver did not notice.

The question of why it was necessary to make a power part from such a fragile metal worries many “victims”. The answer is actually quite simple. With its fragility and rapid destruction in the event of an impact, the crab saves more important and expensive parts such as a “TV” or a spacer.

A broken or cracked crab is a pretty big problem if you find yourself far from home and a service station. The fact is that in the event of complete destruction, you most likely will not be able to get home even at a very low speed. Due to the fact that the front end of the lever remains unattached and simply hangs in the air, the wheel becomes uncontrollable and begins to move either backwards or forwards. As you understand, in this case you can only get home by “carriage”.

It should be noted that a malfunction of the crab does not always manifest itself in the form of a completely immobilized car; it often happens that the fastener itself is absolutely intact, while knocking noises are heard while driving over uneven surfaces. It’s quite simple to check whether it’s a crab; you just need to drive into a “pit” or lift the car on a lift. The presence of play indicates wear in the fastener and requires immediate intervention and replacement of the faulty crab.

In this article you will learn how to replace a crab on a VAZ 2115 at home if it malfunctions. The work is simple and does not require special skills or tools, the main thing is to follow the sequence of actions.

How to replace a crab on a VAZ 2115 with your own hands - step-by-step instructions

We drive into the pit, put the car on the handbrake, install wheel chocks, and jack up the front end.
We dismantle the protection and remove the front bumper.
Using a “24” wrench, unscrew the rod nut.

After this, you need to unscrew the three bolts securing the crab to the platform and remove it

We install the new crab in place and fasten it with bolts.

Further assembly is performed in reverse order. Before tightening, we lubricate the fastening bolts with graphite or, in extreme cases, with polish, this will make your life easier in the future.

That's all I wanted to say! As you can see, there is nothing difficult in this work. Now you know what a crab is, why it breaks and how to replace it if it malfunctions. Thank you for your attention and see you again at VAZ Repair.

Replacing VAZ 2109 crabs with your own hands

Crab – bracket securing the car suspension brace

A common problem with “nines” is the destruction of the bracket that secures the front suspension brace of the car, which is located under the front bumper. Replacement of the VAZ 2109 crab is necessary in case of its destruction, in case of accidental bumping into a high stone or curb, as well as cracks due to “fatigue” of the metal. It is made of a rather fragile aluminum alloy silumin, which is easily destroyed upon impact. When the “crab” is destroyed, it is necessary to replace the VAZ 2109 crab, since the front end of the lever loses its fastening, hangs freely in the air, and no longer holds the front wheel of the car in the desired position.

Clutch Lada Kalina

The exhaust system caused trouble. By the sixth ten thousand, the muffler pipe broke off - as smooth as a knife, it was cut off close to the bracket. There are high vibration loads here, the pipe is weakened by corrosion - where else can it break? As soon as the pipe was replaced, the resonator leaked. And while changing it, they found a more serious malfunction: the honeycomb filling of the converter dangles and rattles in the body of the catalytic manifold. It is natural to assume that it has already been partially destroyed - and this promises new adventures. However, the test showed that the “aging coefficient” of the neutralizer is still half the critical value, and toxicity is normal. And we reasoned: the car is Euro III, which means we’ll wait until the self-diagnosis turns on the warning light, then we’ll think about replacing it.

What does this threaten?

As a result of a breakdown, the wheel begins to move backwards or forwards. Further use of the car is simply impossible. If this happens far from populated areas, you can only call a tow truck. Most often, two types of breakdown occur - complete destruction or separation of one bolt, together with a nut, and the threads of the remaining two nuts are stripped. There are also two ways to deal with such a breakdown: perform the entire repair procedure yourself or seek help from a specialized automotive workshop .

Let's get started

The brace bracket began to be called a “crab” because of the four existing holes for bolts, giving it some resemblance to a claw. You can determine if a crab is broken by the characteristic “crack” that appears in the front of your car. You can look at its condition and determine the scale of the destruction without even lifting the car. We choose the first solution - replacing the crabs on a VAZ 2109 yourself, it’s much cheaper and not presents particular difficulties:

First, we purchase a new crab and a set of bolts for it; on old ones, the threads may be torn off
First, we roll the car onto a pit or overpass
Then you need to put the car on the “handbrake” (parking brake) and support the rear wheels with “shoes” (or wooden blocks to prevent it from rolling away)
Raise the front of the car with a jack
Remove the bottom protection and bumper
During work, you need to remove the stretcher, if you don’t remove it, then you need to make sure that it does not interfere with you

Bolts securing the crab to the platform

First, unscrew the remaining mounting bolts, if they did not come out of the “crab” when the car hit
Remove the spacer washers one by one
We recommend that you immediately count the number of washers removed from each hole and remember the order in which they were installed
When screwing on the new “crab”, first do not forget to put all the removed adjusting washers in their places; install the washers in the reverse order
Then we screw in the bolts of the crab VAZ 2109, securing the brace bracket in place
We tighten them with force, but without fanaticism, so as not to tear them off
This completes the replacement of the crab for the VAZ 2109, but it doesn’t always turn out to get off so easy
It happens that the platform breaks along with the stretching bracket

We buy spare parts

When, having unscrewed the bracket, you discover that a crack has formed on the platform, do not rush to replace the platform, the crack can be welded. Sometimes, however, it becomes necessary to replace not only the bracket, the bolts on the crab VAZ 2109 and the platform to which it was attached also suffered ( and it happens that both platforms or both brackets, left and right):

Then in the car store we purchase a reinforced plate to which nuts are welded to attach the “crab”
When choosing, special attention should be paid to the quality of the welded nuts, since your safety when driving your car depends on this.
If there is no particular choice, and the nuts were welded to the plate with one welding point (or two), then you need to independently weld all the nuts in a circle in order to strengthen their fastening to the plate
Be sure to purchase new bolts for the VAZ 2109 crabs so that microcracks or other defects do not surface later
When choosing traction brackets, you should carefully choose not only the material from which it is made, but do not forget about the thickness
The best option for installation would be a silumin bracket with maximum rib thickness
Since it is stronger than the factory one, however, it will not damage the “TV” or the spacer during a strong impact
The cast iron bracket is stronger than the silumin one, however, cast iron is also fragile and cracks when impacted, and besides, it can damage the spacer and the “TV”; the instructions do not solve this issue for you
It is worth paying special attention to the strength of the rubber cushion and its clip - the more powerful they are, the longer the part will work
We recommend choosing a crab that has a polyurethane cushion
You should not take an inexpensive one (the low price is alarming), or without packaging, we remind you about possible counterfeits!
And don’t forget that there are right-handed and left-handed brackets and platforms; when replacing, this is of great importance

Cost and features of brands

Let's start with, which specializes in the production of spare parts for the national automobile industry. Products are certified. Quality standards are maintained in accordance with the standards adopted in the Russian Federation. Brackets of this brand are made by stamping and welding from sheet steel. The bushing material is polyurethane, whose safety factor is higher than that of rubber analogues. The strength of the adhesive connection virtually eliminates separation from the metal even under extreme loads. The “Sitek Profi” variety has increased body strength and rigidity of silent blocks. Estimated cost – 1250 rubles per set.

Products from Autoproduct, designed to replace standard brackets, not only improve vehicle handling, but also reduce the load on the body. They increase the rigidity of the suspension mounting points and allow you to set the caster to more than 2 degrees. Approximate price: 1750 per pair.

Under maximum loads, which means frequently occurring bumps, holes, potholes and other unevenness of the road surface, the “CS-20 DRIVE” mounts will give the motorist the opportunity to control the stability of the vehicle and the separation of the wheels from the highway.

Imported three-component poured polyurethane, including prepolymer “CS3516-B”.
Mixed compounds of polyols "CS3516-65A" and catalyst "CS3516-C".

The part is an original development for the CS-20.

Improved controllability.
Wear resistance.
The service life is several times longer than rubber analogues.

The described benefits remain at any time of the year. Temperature range: from -60 to +140 degrees Celsius. Price – 650 per unit. At the same time, the standard Tolyatti one has a range from 344 to 383. Polyurethane fasteners from the PIK company cost from 394 to 438 rubles. Sports “crabs” “Tehnomaster” will be sold to you for 1 thousand 350 rubles - a pair. Among the stated advantages are increased rigidity and improved controllability of the machine. Due to the installation of bushings of smaller diameter.

If we talk about more budget options, the reinforced Inter-auto bracket sells for 275 rubles apiece. Weight 535 grams. Dimensions 15*13*7 centimeters.

From all of the above, we can conclude that on average standard mounts cost from 275 rubles per unit. High-strength sellers estimate 650-900.

Replacement of pads

If welding the platform does not make sense (the thread of the nut or the nut itself is broken, the bolt securing the VAZ 2109 crab is broken), then a grinder and welding will be needed here.

Tip: When starting to replace the site, be sure to close the radiator, and if welding is performed from the passenger seat, then also close the generator from sparks. There is no need to remove them; this is an additional and unnecessary waste of time and money (if the repair is carried out at a service station).

Let's move on to actions:

Attach the plate and mark the places for future cuts
Using a grinder, remove the old platform, rusty metal and clean the areas around the cuts; when welding, it is important that the metal is clean
Before performing welding work, you need to remove both terminals from the battery
Weld the plate firmly
The quality of the seams is important here; it must be good, since the part operates under conditions of increased loads, so it makes sense to entrust this work to an experienced welder

The bracket is screwed to the overcooked platform, although the quality of the seams leaves much to be desired, and they were clearly too lazy to clean them

To prevent your car from looking like in the photo, after completing the welding work, you should clean the seams and, to increase protection against rust, coat the surfaces with anti-rust (for example, Tamak) and cover with primer
Attach the stretcher (if you removed it), screw the bracket into place, tightening each bolt of the VAZ 2109 crab (again, carefully, do not break the bolts) Then attach the bumper (see Removing the front bumper of the VAZ) and the lower protection
In the future, when operating the car, it is recommended to check the brackets after each strong impact.
It is recommended not to drive with a broken (split, cracked) “crab” unless absolutely necessary (this is dangerous for the health and life of people around you and for you too). Faulty (damaged, cracked) “crabs” discovered in time should certainly be replaced with new ones as soon as possible
This measure will help save your money, as well as your health and life. Replacing the brackets is complete, everything is simple and completely doable on your own.

New warning triangle: installation requirements

Today we have a new addition to the homemade car section: replacing the crab mount for a VAZ 2108-99 with your own hands.

Good day to all. Recently someone came to me with a “problem” - they couldn’t tighten the bolts to secure the crab. A quick inspection yielded the result: the fastening in the body had rotted and, as a result, the nuts into which the bolts were screwed had fallen off.

In the photo I have cut out a fragment of the body, on which the places for the nuts are clearly visible. It was cut out using a grinder. Stores sell ready-made products that just need to be welded in place of the old one) But we are not interested in it)) After all, we are homemade. Therefore, a piece of corrugated sheet metal measuring 20 cm by 100 cm was purchased at a metal warehouse. Its thickness was 3.5 mm, which is quite enough for our needs. I cut a piece from the sheet a little larger than our old mount. I don’t mention the dimensions of the parts, because... it was all done locally or according to a template.

Using a grinder, I adjusted the dimensions to the required size, i.e. at the location of our cutout.

Having placed the crab on the lever and attached it to the plate, I immediately marked the locations for the holes. Having drilled holes with an 8 mm drill, I got such a product.

Taking a crab and bolts with nuts, we assemble it all on the knee and get a product in which the nuts are scalded. Assembly on the elbow is necessary so that later during installation there will be no problems with bolts getting into the threads.

We screw the crab into place and adjust the product immediately into place, while making potholders.

After grabbing the product in place, unscrew the bolts, remove the crab and scald it with a continuous seam along the cut lines.

Unfortunately, the quality of my seam left much to be desired. I cooked it semi-automatically, but practically didn’t use it (I don’t know how)… But, judging by the seam, it turned out quite strong. Moreover, the reinforcement of the load-bearing lower part of the radiator frame and, accordingly, the mounting of the crabs are made from the same corrugation. This reinforcement was made by trying it on on site and cutting it with a grinder.

The photo shows a cut in the sheet. It is needed to bend the part.

All this was bent with the help of a hammer and some mother... The cut line needs to be welded for strength. Having applied the product, we get a completely acceptable result. All that remains is to drill the holes for the crabs and weld them.

Unfortunately, I can’t post a photo of the finished result, because... For some reason, another person will complete the work. And so everything should turn out strong and reliable.

Replacing a crab on a VAZ 2114

Faulty crabs are a common problem with Lada Samara of the first and second generations. The brackets are made of a rather fragile material - silumin, so during prolonged use or increased load on the chassis they simply collapse. The destruction can be complete or partial (when one of the four fastenings comes off).

How to change crabs on a VAZ 2114

This instruction will be useful not only to owners of “fourteeners”: given the similarity of design, owners of first-generation Samaras can also use the repair work algorithm below.

Before you begin the operations described below, read the Lada 2114 operating manual to remember the correct location of the part, quantity and type of fasteners.

To carry out repair work, the motorist will need:

Set of spanners;
Container for fasteners;
Slotted screwdriver;
Spray can VD-40;
Hammer (just in case).

It is better to carry out work indoors, namely in a garage with a “pit”. Before starting manipulations to replace the “crab”, you need to turn off the power to the car by disconnecting the battery terminals.

So the algorithm of actions:

We roll the car into the pit. Don’t forget to put wheel chocks under the wheel;
We dismantle the front bumper of the Lada;
Removes engine protection from the bottom of the car;
Unscrew the rod nut;
We unscrew all the bolts of the old fastening or what is left of them. It is important not to lose the remaining washers. The washers have an adjusting function; they need to be placed in the new mount in the appropriate quantity;
We install the new part, tightening the bolts as much as possible. It is important not to overdo it so as not to break the fasteners.

Often, not only the bracket itself breaks, but also the platform on which it is placed. Replacing the mounting pad is not a simple process like the one described above. Most often, the breakdown of the crab platform is characterized by the formation of a deep crack in the body of the part.

For a short period, you can get by with welding. First you need to buy a thick metal plate. Automotive stores sell blanks with pre-welded nuts for “crabs.” Using the substitution method, you need to mark the places of the cuts on the workpiece. The surface of the plate must be cleaned as much as possible from rust: a grinder will do.

To carry out the work, you need to contact a qualified welder who can provide the necessary strength parameters of the seam. When the new platform is welded, follow the steps of the algorithm for installing a new VAZ 2114 crab.

If after the repair the controllability has deteriorated (the car begins to noticeably pull to the side), then immediately contact the service center and do not forget to mention the repair work carried out.

Specialized fastenings in the VAZ 2115 car, more popularly known as “crab”, quite often require replacement or repair in cars of this brand. The mechanism is a kind of bracket for fastening the extension. The original name comes from its shape. The product consists of a bracket with holes for bolts, which is why this mount looks like a crab.

Today, such a mechanism can only be found in cars of several brands. Quite often, various situations happen with VAZ 2115 cars, resulting in deformation or breakage of the element. Experienced professionals who repeatedly deal with the repair of these car brands recommend that owners treat the car with care so as not to damage the specialized bracket. However, given the state of our roads, this is quite difficult to do.

This is where the backlash usually occurs

Emergency situations and their solutions

Quite often, quite experienced owners of a VAZ 2115 car install a “crab” made of titanium alloys. This solution is highly durable and guarantees a high level of safety at various speeds under conditions of high loads. If damage or cracks occur, it is recommended to move slowly or call a tow truck to deliver the vehicle to a service center.

If the crab is completely torn off, it is necessary to call a tow truck and go directly to the service station so that experienced professionals can weld or completely replace such a spare part. An important condition for operating a vehicle in various situations is the level of damage that determines the ability of the vehicle to move independently.

Extra Strength Crab

Features of performing repairs and self-replacement of the crab on a VAZ 2115

In order to begin independently replacing this part or repairing it, you must have the following tools and materials:

Standard set of sockets or spanners;
Specialized liquid VD-40;
A reinforced pipe, which may become necessary if the fasteners, that is, the bolts on the bracket, are too oxidized.

If the owner wants to carry out independent repairs, then it is necessary to have a specialized welding machine and some experience in using such a unit.

Step-by-step instruction

Experienced service center professionals have created successive steps that will help the owner of a VAZ 2115 independently replace the “crab”:

place the vehicle on the pit;
turn on the handbrake;
install wheel chocks;
use a jack to raise the front of the car;
dismantle the protection;
remove the front bumper;
unscrew the rod nut;

unscrew several mounting bolts;

dismantle the mechanism;
install a new element (or a restored old one);
tighten the bolts;

carry out installation according to the previous principle, but in reverse order.

Recommendations from experts

It is recommended: before finally securing the bracket bolts, they must be lubricated with a specialized product so that they do not oxidize, and in the future this part can be replaced without any problems.

It is important to note that a faulty bracket may not always completely immobilize the vehicle. Thus, if any errors are observed in the functioning of this mechanism, it is important to carry out independent diagnostics or contact experienced specialists.

During the operation of the car, play appears repeatedly, which indicates negative changes that have occurred with the bracket. In such a situation, it is important to inspect the vehicle and, if necessary, replace the faulty mechanism.

Crab on VAZ 2114: operation and replacement

Very often, on cars produced by AvtoVAZ, a malfunction occurs such as a breakdown or even complete destruction of the front suspension brace fastening. The crab on the VAZ 2114 is no exception (this is what many drivers call this fastener). The main reason for such frequent breakdowns is the material from which the crab is made, namely various aluminum alloys (like silumin).

If, while driving, a car touches high protruding elements - stones or bricks, with its brace fastening, then in most cases this leads to the destruction of the latter.

It would seem, why did the designers choose this particular material, since crab 2114 could have been made of steel? The answer here is quite simple - this element is made fragile specifically in order to save other, more important and expensive elements of the car suspension when it collapses.

Is it possible to drive with a faulty crab?

In most cases, driving with a faulty brace fastening is impossible. This is caused by the fact that the wheel on the damaged side becomes simply uncontrollable, and movement even at a minimum speed turns out to be extremely difficult.

If the crab is completely broken, you should stop driving the car until it is repaired, and if the breakdown occurs far from home, then call a tow truck.

Sometimes a slightly different situation happens - it seems that the mount is not damaged, and the car is driven normally, but at the same time a knocking sound is periodically heard from one of the wheels (especially clearly when going over uneven surfaces).

This may be caused by the fact that the fit of the fasteners on the crab itself has worn out (due to the fact that it is made of fragile material) and backlashes have appeared.

This is very easy to check - you just need to put the car on an overpass or hang it on jacks, and then inspect the mount. If it turns out that backlashes have indeed appeared, then the crab should be immediately replaced with a new one.

Driving a car with a worn-out crab that has strong play can lead to its spontaneous destruction even without colliding with an obstacle (which is extremely dangerous, as it can happen when driving at high speed).

How to replace the crab with a new one?

If signs of wear or damage are detected, it may be necessary to replace the crab with a VAZ 2114. This is quite simple to do and can be done by every car enthusiast.

The only thing you will need is the presence of an inspection hole or overpass and a minimum set of tools:

jacks;
shoes;
flat screwdriver;
set of heads with ratchet;
24mm wrench.

The entire replacement procedure is performed in the following order:

We install the car in the pit.
We install the shoes under the rear wheels.
We hang the front on jacks.
We dismantle the protection and front bumper.
Take a 24mm wrench and unscrew the rod nut.
Unscrew the 3 bolts securing the crab.
We remove the destroyed crab.

After this, we take a new bracket and mount the VAZ 2114 crab in exactly the same sequence, but in reverse order. As you can see, everything is quite simple and does not require much time. If necessary, the entire replacement procedure can be performed even on the road (provided there is a suitable place for this).

What to consider when choosing a new crab?

As stated previously, all front brace brackets are designed to be frangible to ensure the safety of more critical parts when impacted by obstacles.

At the same time, all crabs currently on the market can be divided into the following groups according to the materials from which they are made:

While the first two types of crabs work on the same principle (they break apart in an accident and differ only in their weight and strength), steel crabs work somewhat differently. They are made of a powerful metal base with a welded steel strip that serves as a traction mount.

Replacing the crab for VAZ 2108, VAZ 2109, VAZ 21099

Welcome! Crab - thanks to it, the brace is attached to the body of the car, crab this name generally came from the people, in fact it is an ordinary bracket for attaching the brace, but it got its name because it is made in the shape of a crab (This bracket has holes for bolts, they are very similar to a claw crab), only two families of front-wheel drive cars are equipped with these brackets (the Samara family and the Samara 2 family, but they were removed on the tenth family) and therefore on these cars (and on dozens too), you need to drive much more carefully, twist the crabs are made not of titanium alloy, but of ordinary aluminum, and if a large stone hits them while driving at high speed, for example, you can immediately stop and check the crab, if it is damaged (a small crack), then get into the car and carefully drive to at home, if it is completely torn off, then in this case call a tow truck and take the car either home or directly to the service station (It depends on how the crab was torn off, if you do not know how to handle welding, and the crab along with the platform was torn off, then you can immediately go to the service center, if the platform remains in place but the crab has also fallen off, then first look at the threads where the bolts are screwed in; if it is all torn off, then also go straight to the service center, because in this case the platform will need to be changed).

Note! To change the crab on a family such as the Lada Samara, you will need to stock up on: Socket wrenches, as well as a liquid like WD-40, and perhaps you will also need a reinforced pipe (This is if the bolts are very acidified, so that you can use it as an additional lever)!

Summary:

Where are the crabs? There are only two of them and they are screwed with three bolts to the platform, in order to get to them you won’t need to remove anything extra, but only the guy wires that they hold will have to be disconnected (Both guy wires are indicated by blue arrows for clarity), in some cases, people also and the front bumper is removed from the car (If you suddenly need this, then read the article entitled: “Replacing the front bumper on a car”, the entire removal procedure is described there), but as for the extensions, they are attached using two nuts (Each extension is attached one nut per crab), unscrewing them (indicated by green arrows) and unscrewing the nuts securing the crab, you can easily remove and exchange it on your car for a new one, and the crabs themselves are indicated by red arrows for clarity.

When should you change crabs? They must be replaced if deformed, and even if you have been driving a car for a long time, and the crabs have never been changed, then always remember one thing, from time to time the metal ages and we recommend that you take a good look at the crabs in the near future and look for are there any cracks in them or any other kind of deformation (maybe it is only attached to two bolts, since the thread is broken on one of the welded nuts), if you find any of the above, then immediately replace the crab in the car and do not use it so that the crab does not suddenly vomit and the car does not lose control, when the crab rips off, the stretcher immediately falls, and the front wheel either falls forward or backwards and no longer stands in its former position and further operation of such a car is strictly prohibited, otherwise all this can lead to bad consequences.

Note! Most often, the crab has to be changed when the car owner runs into a large stone lying on the road at speed or when hitting a curb, but in cases where the car is operated carefully, as a rule, nothing like this happens with crabs, so drive more carefully and do not run into extra large bumps and crabs will serve your car for a long, satisfying life!

How to replace crabs on a VAZ 2108-VAZ 21099?

Note! When replacing crabs or one crab of some kind, be sure to stock up on new bolts, because the old ones can be deformed and have cracks, and the heads on the bolts can also be torn off (And these bolts constantly turn sour and unscrewing them can be so problematic, which is why mostly the heads come off)!

Removal: 1. First, lift the front part of the car on a jack and secure it well by placing blocks of wood under the sides of the car and for better stability, put something under the levers, just in case (In general, you will need to hang the front part and fix it well, everyone than possible), then slightly loosen the nut that secures the guy wire to the crab (Indicated by a blue arrow) and proceed to unscrew the three bolts securing the crab to the platform (Indicated by red arrows), and when the bolts are unscrewed, carefully lower the crab, completely unscrew the fastening nut stretch marks and take it out and leave the stretch mark, let it hang.

Note! Spacer washers will be installed under each bolt; they will need to be installed in exactly the same places, in the same quantity and exactly as they were, so when you turn out the bolts, carefully remove these washers and remember their location under the bolts!

Installation: The new crab is installed in the reverse order, in this case all its fastening bolts are replaced with new ones and the washers are installed in the same places where they were previously.

Note! Screw in the crab fastening bolts with good force, but we don’t recommend screwing them in very powerfully, they will turn sour and then you simply won’t be able to unscrew them in the future, but there is one But! After removing the crab, inspect the platform to which it is bolted and if suddenly you find cracks and other types of deformation on it, then you will have to resort to replacing the platform with a new one, but by the way, it is not always necessary to change it immediately when a crack is detected, for example, if the crack does not is large, then try welding it and the platform will continue to serve your car faithfully, you just have to keep an eye on it, but if the platform is very deformed, if its nuts are torn off and the bolts securing the crab simply no longer fit, then it will have to be replaced with a new one , to do this, you need to cut out the old platform with a grinder, and buy a new one and weld it by welding, that’s all, the replacement of the platform is complete, but just be sure to weld all the seams well, before welding, be sure to clean the metal from dust and dirt, and so on!
