After a long and merciless operation of the Audi A4, car owners have to face the breakdown of many parts. Often fails and CV joints - the hinge of equal angular velocities, causing the car wheels in motion due to the transmission of torque when turning up to 70 degrees. Drivers often call this important element a “grenade”. The CV joint consists of an outer and inner cage, a separator and 6 balls.

Also, the hinge of equal angular speeds have rubber covers (anthers) that protect it from water and dirt. If the rubber case remains tight, despite wear, it can be replaced. In the case of rupture of the anthers - need to replace the CV joints.

Steps to replace the hinge

To replace the constant velocity joints, you should use a lift for the car, prepare a screwdriver, vice, spanner keys and pliers. You will also need new anthers, hub nut and special grease. These consumables are completed with a hinge.

Replacement of the CV JOINT is made in stages:

• First of all, unscrew the hexagon bolts of the hinge and the wheel. After that, lift the right side of the car with a jack, remove the wheel and brake disc with the caliper.
• Next to access the CV joints, you need to remove 2 levers at the top, unscrewing the bolts in the rack.
• The next step is to pull out the hinge. To do this, unscrew the bolt on it, remove the clamps and knock out the old CV joints with a hammer.
• Then the "grenade" should be disassembled: remove the washer, rings and anthers. After this, the seat is thoroughly cleaned of the old grease and installed on the drive a new CV Joint with all the components in the reverse order of disassembly.
• After shrinkage of the locking ring on the drive, clog the new CV joint and put on new anthers so that they do not get dirty in the grease. At the same time the groove of the rubber cover should stand clearly in the groove of the hinge.
• As a result, tighten the clamp, put on the tip, put the wheel and tighten the bolts of the drive to the hub.

When replacing the anthers, it is desirable to use screw models instead of band clamps. They ideally prevent dirt from entering the hinge and are easy to install. In addition, before assembling, a thin layer of fresh lubricant is applied to the two clips for easy advancement to the CV joints. If the anthers at the service station changed in a timely manner, then there will be no need to replace the hinge.

The process of replacing the CV joint usually lasts 1-2 hours, depending on the experience of the car owner. However, it is best to seek the help of a professional at a service station. To avoid costly replacement of the hinge of equal angular velocities, damaged anthers should be replaced promptly.

Problems in the SHRUS work begin with a slight rattle when turning one of the wheels. The specific sound in case of malfunctions of the hinge can be heard at the maximum turning of the wheel. In such cases, it is impossible to delay the repair of the hinge of equal angular velocities, otherwise it can completely collapse while driving, which is fraught with huge problems.
