Replacement of hub bearings on Lada Largus

A wheel bearing is used to reduce friction between the steering knuckle and the hub. Lada Largus has four double-row bearings that need to be changed from time to time. Today we will tell you why they fail, what signs of wear look like and how to change the hub yourself.

How to identify a faulty wheel bearing Largus

To understand what the symptoms of a failure look like, you need to know how bearing wear occurs. Between the outer and inner races of the bearing are balls that use the rolling effect to reduce friction. To prevent wear of the ball, the entire cavity is clogged with grease.

Riding through puddles washes out the grease, causing the bearing to dry out. The situation can be aggravated by the ingress of dust and dirt, which acts on the parts as an abrasive.

Long-term riding on such parts leads to displacement of the inner race, and a lack of lubrication causes a buzz when driving. In addition, driving for a long time with a bad wheel bearing can cause the wheel to seize while driving! This may cause an accident, especially on slippery roads.

Common symptoms of wheel bearing wear

The symptoms of a malfunction of the hub in Largus manifest themselves in the form of stages:

1. A dull noise when driving when there is a load on the wheel.
2. Clicks on touch.
3. Metal scraping.
4. Cradle.

Clicks appear when one of the balls begins to crumble, its somersaults inside the cage will be reflected in the form of clicks when starting or stopping.

If you continue to ignore this, a metallic screech will be heard as the rest of the balls begin to approach each other. Most likely, all parts are already covered with rust.

Riding with a rattle will not keep you waiting long. At the “ideal” moment, the wheel jams, causing the car to stop. It is no longer possible to move on.

How to determine from which side the Lada Largus bearing is buzzing

The easiest way to diagnose front wheel bearings. It can be done on the go. To do this, follow these steps:

1. Drive at the speed at which the hum is most noticeable.
2. Turn the steering wheel first in one direction and then in the other direction, imitating a long "snake". Watch out for noise while driving.
3. If, for example, when moving to the right, the hum stops and increases to the left, then the right wheel bearing is faulty.

Why is it correct? Because when turning to the right, the wheel is unloaded, and when turning to the left, it is more loaded. Noise only appears under load, so it is the right bearing that needs to be replaced.

The rear wheel hubs on Lada Largus are more difficult to diagnose, since the load on them is distributed more evenly. Therefore, the wheels should hang and try to rotate in a vertical and horizontal plane - there should be no backlash!

A bad sign is noise when the wheel is spinning, as well as its quick stop during rotation. The same rule applies to the front wheel.

How to choose a good wheel bearing for Lada Largus

The service life of bearings is affected not only by operating conditions, but also by the manufacturer. Bad behavior won't last long. Below is a table of front wheel bearing manufacturers that are definitely worth buying:

Creator	Front with ABS	Front without ABS
Original	7701207677	6001547696
SCF	VKBA 3637	VKBA 3596
SNR	R15580/R15575	GB.12807.S10

When buying a front wheel bearing with ABS, you must consider the number of elements on the magnetic tape of the bearing. To do this, it is advisable to remove the old bearing and, accordingly, select a new one. If you install the wrong bearing, you may find a fault in the ABS. Only SNR gives different numbers for different parts.

The rear bearing according to the factory spare parts catalog is offered assembled with a drum. However, you can buy the original bearing with catalog number: 432102069R.

How to change the front wheel bearing on Largus

After identifying the symptoms of a bad wheel bearing, it's time to replace it. The process must be carefully prepared. Knowledge alone is not enough, you need a special tool.

What may be needed when replacing parts

In addition to the standard hand tool of the car owner, a press is also needed to replace the wheel bearing with a Lada Largus.

To remove the old bearing and install a new one, all actions must be performed using special hydraulic equipment. However, you can replace:

• screw;
• cartridge from an old bearing and a hammer;
• special manual extractor.

All methods are good in their own way, but discs are considered the best of the inexpensive ones listed.

Problems can arise only in the convenience of its use. But with a hammer there is every chance to unscrew the new bearing, which will further affect its resource.

But before changing this part, it is necessary to carry out a number of dismantling measures:

1. Remove the front wheel.
2. Loosen the hub nut.
3. Remove the speed sensor (if equipped with ABS).
4. Unscrew the clamp holder and hang the clamp to the spring using the loops.
5. Unscrew the brake disc mount using an impact screwdriver and a Torex T40 bit. Remove the disk.
6. Remove the brake disc boot.
7. We release the steering knuckle: remove the tie rod, ball joint and unscrew the mount of the rack to the steering knuckle.
8. Remove the steering knuckle from the vehicle.

Now it is possible to transgress to the suppression of rolling. You need to do this if you have the appropriate skills. Otherwise, there is a good option - take the node for suppression to the nearest service.

How to repress a wheel bearing on Largus

To do this, rest the steering knuckle with the hub down in the vise jaws or two wooden blocks. We put on a frame with a diameter of 36 millimeters or a head of the appropriate size on the hub. Then we hit the frame with a hammer or mallet until the sleeve comes out of the fist.

The inner track usually remains in the hub. To remove it, you must use a special extractor or cut it with a grinder.

Be careful not to leave any burrs on the bushing seat.

Next stage:

1. Remove the circlip from the outer race of the bearing.
2. Install a mandrel with a diameter of 65 mm in the holder.
3. Knock or press the outer ring out of the steering knuckle.

Before installing a new bearing, it is necessary to clean the seats in the hub and steering knuckle.

To push, do the following:

1. Install the bearing in the neck and press it in with a press. You need to press the outer clamp with a 65mm mandrel.
2. Install the circlip into the groove in the steering knuckle.
3. Push the cube into the inner race.

It remains only to assemble the suspension parts in the reverse order of disassembly.

Replacing the rear wheel bearing

With a rear bearing in Largus, everything is much simpler. The car owner can replace the drum assembly, thereby solving the problem with the brakes, if any, or change the bearing separately.

By choosing the second option, you can save a lot, but you will have to look for the bearing itself.

To replace you need:

1. Remove the rear wheel.
2. Loosen the hub nut.
3. Remove the drum from the steering knuckle.
4. Remove the retaining ring from the bearing.
5. Press the bearing back into the drum.

Use a 27 head as a pressing mandrel. Remove the bearing from outside the drum. And push in. In addition, the condition of the pin must be checked. If it shows obvious signs of wear, such as scuffs, it should be replaced.

Then assemble in reverse order. This completes the bearing replacement.

To summarize

It is clear that the signs of failure of the wheel bearing on the Largus should not be ignored. Therefore, be sure to change the worn element, guided by this instruction.
