Features of replacing the VAZ-2107 driveshaft crosspiece: 3 important tips for choosing a part

another replacement of crosspieces is already a tradition

Replacing
crosspieces is already becoming
a good tradition
, at first I didn’t realize that
the crosspieces in
classic Lada
are consumables
that sometimes wear out faster than the front brake pads run back...
wow!
the car started to boil and crunch

...well, I think
I recently changed
10-15 thousand ago, probably the handbrake needs to be tightened, the handbrake cable rubs against the cardan, I drove until I finally got the skip, I got to the service garage - oops, the crosspieces are a mess, at the same time they changed the cardan bearing - and it seems the resonant hum from below that has been there since purchasing the car has disappeared

fuck

no words... I change crosspieces almost
every year
, only now I realized that
I need to choose a manufacturer
and not run into
a fake.
For some reason, the crosspieces from Volga Auto Prom have been covered up very quickly already 2 times in a row, I’m switching to imported crosspieces (GKN, Trialli)

there was no time to think and there was 1 piece of Cedar

and 1 piece
GKN
(standard manufacturer but many fakes), they installed it, I’ll see how long it lasts

CARDAN were highly praised

, but I already installed others ((

Which crosspiece is better to install?

Car service specialists say that if the time has come to change the crosspiece, then it is better to change them as a set, both of them. In fact, this is not always the case. The front crosspiece, as a rule, lasts much longer than the rear one. Sometimes three crosspieces are replaced at the shank, but at the outboard bearing the crosspiece remains fully functional.

Experts advise not to “kill the ears of the cardan”, and not to change the crosspiece unless necessary.

When purchasing, you should not save on cost, it will be more expensive. Quite good crosspieces made in Germany are of high quality and come complete with retaining rings, which come in very handy if the “original” ones break during disassembly.

Crosspieces

(with oiler) are made of a special stainless steel alloy that is resistant to corrosion. The manufacturer guarantees high quality based on multi-stage control during the production process.

Crosspieces from Weber, GKN, etc.

The only disadvantage of imported crosspieces is that the retaining rings often need to be adjusted.

Well, the most affordable crosspiece for the VAZ 2107 of domestic production. Quality depends on your luck.

also replaced the cardan outboard bearing

We also replaced the rear gearbox oil seal, the gearbox is leaking, we need to change the top gasket and the front gearbox oil seal

PS:

after replacing the crosspieces the car does not creak! The resonant hum of the cardan has disappeared! I haven’t heard that for a long time, it was as if a bucket was tied from below - that’s how I drove

Features of replacing the VAZ-2107 driveshaft crosspiece: 3 important tips for choosing a part

In the age of advanced technology, more and more cars have front-wheel drive, which does not use a driveshaft with hinges. Nevertheless, many companies continue to make rear-wheel drive cars, using the old classic drive-wheel drive scheme. Along with Mercedes and BMW, our VAZs continue the tradition. Therefore, car owners are interested in how to replace the VAZ-2107 driveshaft crosspiece themselves.

Crosspieces: dimensions, markings, applicability

The crosspiece is one of the most important elements of the driveshaft.
As calculations of the loads on the driveshaft show, the spider is the weakest part of the driveshaft, so the quality of the spider is very important. Crosspiece for domestic automobiles and tractors

Node device

Before you begin dismantling it yourself, you need to at least in general understand the structure of the entire unit, then repairs can be done according to all the rules. Cardan shaft device:

To the eternal question, how many crosspieces are there on this car, there is a very clear answer: two.

Structurally, everything is done exactly this way due to the fact that the gearbox and the rear axle gearbox are not located in the same axis, that is, they are offset relative to each other. From this it is absolutely clear that the driveshaft cannot be solid, since this is structurally impossible.

The design also provides a suspension device - an additional support consisting of a rubber cushion enclosed in a steel cage and a bearing in the center of the structure.

This is the brief structure of this node.

Removing the shaft from a VAZ 2107 car

Attention! Before separating the transmission parts relative to each other, you need to make marks with chalk so as not to rotate the position of the parts differently and not cause alignment problems!

• We hang up any drive wheel using a jack;
• We put the gear shift lever, or “stick”, in neutral, lock the “handbrake”;
• Remove the safety bracket by unscrewing the nuts and washers;

• Now we release the coupling from the gearbox flange by unscrewing 3 nuts;

• We turn the cardan, take out all the bolts from the flange and coupling; to make work easier, you can carefully knock them out with a punch and a hammer.

• Now you can disconnect the front end from the gearbox flange;

• Now we unscrew the nuts of the rear half of the transmission from the differential flange (there are 4 of them);

• Now you can separate the driveshaft and differential flange:
• We unscrew the nuts securing the cross member and remove it;
• And only now we remove the cardan from the VAZ 2107

That's it, the withdrawal is complete. The reverse installation is carried out in exactly the same way, you just need to make sure that the cardan coupling with its liners (2) fits into the grooves of the gearbox flange (1,3).

After installation, you need to check how the cardan rotates with one wheel hanging.

Basic faults

Any component or mechanism sooner or later wears out and requires complete or partial replacement (repair). The most common driveshaft malfunctions:

The latter malfunction occurs for various reasons. The most likely of them:

The signal to replace these parts is increased noise while driving, vibration and extraneous sounds emanating from under the car.

Spare part selection

In order to repair this unit less often, you need to purchase good quality spare parts. The correct choice of crosspiece determines how often it will need to be replaced. Choice of cross:

And another effective way to check. The crosspiece taken out of the package should be placed on a piece of glass - a glass counter is quite suitable, or on the same side-view mirror (removed, of course). Holding your fingers opposite the axis of the cross, you need to try to swing them on this surface. Next, you need to do the same with other axes. Then turn the part and do the same operation again. During the inspection process there should be no knocks on the glass surface, which will indicate the absence of deformation of the part.

You should buy two parts at once, because after replacing one, the replacement of the other will very soon follow. Many people immediately change the bearing of the suspension device, so as not to have to repeat what they have done before, that is, disassemble everything, wasting time and their own nerves.

Preparing for work

You can't do any job without the right tool. You should prepare:

And, of course, it is better to carry out the work on a lift, overpass or inspection ditch - it will be both more convenient and safer.

If work is carried out on the first two structures, then you need to fix the wheels by placing blocks under them, which will prevent unwanted rolling of the car forward or backward. You must always remember safety precautions before removing the crosspiece from the VAZ-2107 cardan or performing any other work under the car.

Removal of worn parts

Replacing them does not present any particular difficulties, and it is not at all necessary to take your “seven” to a service station in order to perform such a simple operation.

Replacing crosspieces on a VAZ-2107 is impossible without dismantling the driveshaft.

This does not require any special training, great skills or special tools - everything is very simply done in a garage. Operating procedure:

Such a tool can be either universal (working for both compression and expansion) or single-acting. However, many craftsmen manage to do this with a simple screwdriver or an awl, which is undesirable for safety reasons.

After all the rings have been removed, you can remove the crosspiece on the VAZ-2107. This is done like this:

Installing new items

Now that the hinge is disassembled, you can begin installing the new part. To do this, you need to remove the new cross from the packaging and carefully remove the caps from it, so that its needle bearings do not fall apart. Further:

All these operations must be repeated with the second cross - there are no differences as such.

Installation of the cardan shaft is carried out in the reverse order of dismantling. To do this you need to do:

Don’t forget about the retaining rings to avoid early failure of the propeller shaft joints! And you also need to carefully, but without fanaticism, tighten all the bolts and nuts. In addition, we must not forget about aligning the marks on the hinge joint.

Now you need to check the car while driving for the absence of vibrations and noise under it.

Step-by-step installation

Before installing a new element, you need to pay attention: is there grease on the bearings and on the cardan cross?
If such a substance is not observed, lubricant will definitely have to be added. In the case of installing a cross with an oiler or grease fitting, lubrication can be done after installing this element, using a convenient syringe that is intended specifically for this process. Installing a new cross will not take much time and the car owner will be able to install this element independently and correctly if the process is carried out in the following sequence:

1. First of all, you need to remove two “cups” from the cross.
2. Next, you need to install the cross into the so-called eyes.
3. Slowly moving the element from one side to the other, the “cups” are put on in their original place. This stage must be performed slowly, making sure that when installing the “needles” do not fall apart from the “cup”.
4. By squeezing the “cup”, it is worth achieving the formation of a small groove, which should appear under the retaining ring. A copper or aluminum attachment will help simplify this process.
5. After installing the locking ring, the cardan is carefully rotated so that the crosspiece moves in different directions. The “cup” is put on the element and compressed again so that the locking wheel can be installed.

At this point, the replacement process is considered complete; every VAZ-2107 car owner can handle such work without any problems. Well, to find any answer to a question on this topic, step-by-step video instructions on the Internet resource will help you, which you can watch at the most convenient time for yourself.

Conclusion

It must be remembered that work done correctly, as well as high-quality spare parts, will help the car owner forget about this unit for a long time. And don’t forget about timely lubrication of the bearings through a grease nipple - then the next repair will not have to be done soon.

Of course, taking on this work yourself or entrusting it to service station mechanics is the job of every car owner. But, taking into account that the owners of VAZs (especially “classics”), as a rule, are not rich people, there is a reason to do this work yourself, thus saving a decent amount.

Which crosspieces are better for the VAZ 2107

In this article we will look at how to replace the crosspiece and suspension bearing of the propeller shaft of a VAZ 2106, VAZ 2107, VAZ 2105, VAZ 2104, VAZ 2101, VAZ 2102. I was prompted to write an article on this topic by the special interest of car owners in the issue of replacing the driveshaft crosspiece with VAZ cars.

What auto parts will be needed for the upcoming work?

The first step is to buy a driveshaft suspension bearing (when purchasing a bearing, check the elasticity of the rubber band and the bearing stroke). The bearing must rotate smoothly and without interruption, which will ensure its long and high-quality operation. The use of high-quality rubber in the bearing increases its service life.

The driveshaft support should be selected according to the catalog number. Catalog number of the driveshaft support VAZ 2106, VAZ 2107, VAZ 2101, VAZ 2102, VAZ 2103, VAZ 2104, VAZ 2105:

If you're on a budget and can't replace the driveshaft support, you can simply replace the driveshaft bearing.

Cardan shafts "NIVA-BELKARD"

In 2005, Belkard OJSC began producing new generation driveshafts for Niva cars: front axle drive - 2121-220 3 012-04 and rear axle drive - 2121-220 1 012-04 . Cardan shafts of this design have been supplied for several years for SUVs "TRECOL", "UAZ", "KIA Sportage". These modifications replaced the previously produced 2121-2203012-02 and 2121-2201010-02 , respectively.

Shafts of the new and old generation in comparison (from the side of the fork bearings...

... and from the bearing side of the flanges)

A distinctive feature of cardan shafts of previous modifications is a thin spline and a pipe with a large outer diameter

...as well as the “square” flange form factor

In the manufacture of modernized cardan shafts at JSC Belkard, a pipe with a smaller outer diameter is currently used - 59 mm (inner diameter 55 mm, wall thickness 2 mm) ...

...as well as flanges with a “round” form factor

The use of progressive design and technological solutions has made it possible to achieve significant advantages compared to cardan shafts of the “old” design produced by Belkard OJSC and cardan shafts from other manufacturers.

The life of the bearing unit has been increased due to the use of the crosspiece 2121-2201025-30 (with external locking) instead of the previous 2121-2201025-20 (with internal locking). The new type of crosspiece uses needle bearings СН192819НРС10 with a stamped housing and a polymer washer installed on the bottom of the bearing. Selective selection of retaining rings made it possible to minimize axial clearances in the hinges .

The crosspieces of the new modification 2121-2201025-30 come with parameters 28 x 65 mm and are secured with external locking rings, the oilers are equipped with protective caps . (while the crosspieces of the old type 2121-2201025-20 were similar to the “Moskvichevsky” 412-2201025-04 with the same parameters: 28x83.55mm, internal locking in the hinge units).

(note: there are also Ukrainian driveshafts for Niva cars with Volgov crosspieces 3102-2201025-01 and parameters 30 x 88 mm. Be careful when choosing a replacement crosspiece!)

Rice. 1 Cardan shaft for Niva cars 1 - sliding fork; 2 — seal of telescopic protection; 3 — splined bushing; 4 - flange; A - bearing with a polymer washer and locking by the outer ring.

Applying a polymer coating to a RILSAN spline bushing and manufacturing involute splines of the sliding fork using cold plastic deformation, installing special double-edge seals made of abrasion-resistant composite material made it possible to reduce axial loads in the spline joint, increasing its reliability and durability by 4-5 times.

Spline 38x2x9H/9d GOST 6033-80 is used (external diameter of splines 38 mm)

Such a spline connection does not require maintenance (lubrication) during vehicle operation, providing the required service life. In addition, due to the minimal force of axial movement in the spline connection, the load on the components of the transmission power units is significantly reduced, resulting in an increase in their durability.

The deep modernization carried out made it possible to increase the service life of cardan shafts for Niva cars by 1.5-2 times.

Produced cardan shafts undergo strict multi-stage quality control inspection. Research and development center DTR of AvtoVAZ OJSC, after a comprehensive comprehensive test in laboratory and road conditions, approved the use of cardan shafts of the design described above in the transmission of Niva cars, in addition, these shafts were approved for Chevrolet Niva cars.

In particular, the test results showed a significant reduction in vibration levels and an improvement in noise characteristics.

How to replace a driveshaft bearing?

In order to change the propeller shaft bearing , it is enough to knock out the old bearing, after first removing the retaining ring. And slowly hammer the new bearing into place.

“When you choose a driveshaft crosspiece, it is better to give preference to the VAZ crosspiece”

How to buy a driveshaft crosspiece for VAZ 2106, VAZ 2107, VAZ 2101, VAZ 2105, VAZ 2102, VAZ 2104?

Before buying a driveshaft crosspiece , you should go through two stages, the first is to select a driveshaft crosspiece and check the driveshaft crosspiece.

I decided to write down information on how to buy a universal joint for a driveshaft because of frequent requests on the Internet about: What are the best manufacturers of universal joints? What are the quality crosspieces? How to buy a high-quality driveshaft crosspiece? How to determine if the driveshaft crosspieces are defective?

Let's look at a list of reliable and inexpensive crosspieces for the VAZ 2106, VAZ 2105, VAZ 2107, VAZ 2101, VAZ 2102, VAZ 2104, VAZ 2103 (Fig. 1).

Checking the driveshaft cross

You can check the driveshaft crosspiece using a regular mirror. Place the mirror on the table surface and place the cross on top. Take the propeller shaft crosspiece by the ends and rock it, checking for any play. If, when checking the crosspiece using a mirror, slight play and knocking are observed, then such a crosspiece can also be installed, but slight vibration will be observed, which is not very pleasant.

Tool for replacing the crosspiece and the outboard bearing of the propeller shaft of VAZ-2101, VAZ-2102, VAZ-2104, VAZ-2105, VAZ-2106, VAZ-2107 (Fig. 2).

Sequence of work for replacing the suspension bearing and driveshaft crosspiece on a VAZ 2106, VAZ 2107, VAZ 2105, VAZ 2104, VAZ 2101, VAZ 2102

How to install the driveshaft crosspiece in place?

Remove the two cups of the crosspiece, tuck the crosspiece into the eyes. Put on the cup (Fig. 10). Install the locking ring and put it on (Fig. 11).

The cardan cross in classic VAZ cars is a cross-shaped joint that secures the rotating axles of the transmission. The VAZ 2107 has two crosspieces: one in the central part, and the other at the junction of the propeller shaft with the gearbox. Replacing these parts on a relatively new car is quite simple. However, over time, the crosspieces rust, and the procedure for dismantling them becomes real torture for an inexperienced driver.

I invite you to read a short article, the purpose of which is to help you select and check the suitability of the driveshaft crosspieces for VAZ-2101, VAZ-2104, VAZ-2105, VAZ-2106, VAZ-2107 . The visitors to my blog convinced me of the need to write this article. How? Yes, very simple. In a fairly short period of time, by email, through the “Question-Answer” section and the feedback form, I received several similar questions from them - Which manufacturer’s crosspiece should I choose for my car?, What high-quality and reliable crosspiece can be installed on a VAZ-2103? , What to look for when purchasing driveshaft crosspieces for Classics? How do the crosspieces of the VAZ-2101 differ from the VAZ-2105? And trying to please everyone and at the same time save my time, I decided to take a few necessary photographs and write this article. I’ll say right away that this material does not present crosspieces from all manufacturers that are available on the Ukrainian auto parts market. Here we will talk only about proven (by me personally and by time)
