Under certain conditions, however, it is possible to disassemble the constant velocity joint in accordance with the instructions given and reassemble it.
Checking the outer constant velocity joint
If the car has been driven for a long time, the constant velocity joint has undergone a certain amount of wear. Excessive clearances in the joints manifest themselves as a noisy beat when the accelerator pedal is released, they become noticeable if the engine is "pushed". If this can be determined after a long period of service of the car, the constant velocity joint can be replaced with a new one without delay.
To disassemble a constant velocity joint, you need a vice to clamp the shaft.
The installation position of the inner sleeve relative to the ball bearing separator and housing should be marked in an appropriate manner.
The shaft is clamped in a vice and the sleeve with the ball bearing separator is folded back. The balls are removed one by one. The balls of this joint belong to a certain group of tolerances and cannot be replaced.
The ball bearing separator is turned until the rectangular holes shown by the arrow are aligned with the edges of the housing. Now the separator is removed together with the bushing.
The sleeve is turned until the segment can be moved into the rectangular opening of the bearing separator and the sleeve can be removed.
All removed parts are checked, and the jamming of the balls is also monitored.
Smooth spots are not an indication that the CV joint needs to be replaced with a new one, as they are simply ball races.
When assembling a constant velocity joint, proceed as follows.
Apply approximately 55 g of type G.6.3 grease to the constant velocity joint.
Insert the separator together with the bushing into the housing.
Insert the balls of the opposite sides, but make sure that they return to their original position in the separator and housing.
Insert a new retaining ring into the constant velocity joint.
Apply approximately 55 g of type G.6.3 grease to the inside of the constant velocity joint.
Place a rubber cuff on the constant velocity joint and secure it with a clamp. To secure it in this way, you should again use special pliers.
Make sure the clamp is properly installed at the other end and carefully insert a screwdriver between the collar and the shaft. This will release any trapped air. Tighten the small clamp securely.
Checking the inner constant velocity joint
After the constant velocity joint is removed, the bearing separator and outer ring are aligned and the separator is removed in the direction shown by the arrow. It is necessary to take into account that the bushing, outer ring and six balls are matched with each other and can only be replaced with new ones as a complete set.
The assembly of the constant velocity joint is carried out in the following sequence.
The ball bushing is inserted into both grooves of the bearing separator, and then the balls are pressed in. To do this, hold the part and press the balls inward along the circumference.
The bearing sleeve is inserted into the outer ring in the following manner:
The inclined part on the inside of the bushing should be directed towards the contact connection on the drive shaft and towards the large diameter of the outer ring.
The sleeve together with the separator and bearings is inserted perpendicularly into the outer ring as shown in the figure.
Note that in each case the wide ball groove (a) and the narrow ball groove (d) in the sleeve are together on the same side when the sleeve is tilted into the outer ring.
The constant velocity joint is pressed onto the shaft, with the shaft supported from below.
A new spring retaining ring is inserted into the groove. If required, it is pressed in well using pliers with a water pump.
The constant velocity joint is reinstalled.
