Checking the condition and replacing constant velocity joints (CV joints) (Opel Astra H)

Examination

1. A clearly failed CV joint can be identified by characteristic impacts when the load changes, and also by ear by the characteristic clicking sound it makes when turning - the sharper the turn, the greater the load on the joint, and the more clearly the clicks are heard.

2. For a more detailed inspection, lift the vehicle and place it on stands. Remove the crankcase guard if necessary.

3. Press the control arm up forcefully and then pull it down (see accompanying illustration), then press hard on the bottom of the wheel and push it outward first, then pull it inward. While checking, watch the joint - if any noticeable play is detected, the joint must be replaced.

Note: When checking, it is necessary to exclude the influence of play in other suspension and chassis elements.

4. Check the integrity of the boot - replace if damaged.

Replacement

Note: Damaged joints are replaced only as a set. Tripod type CV joints, if they fail, are replaced as a set with the shaft.

5. To replace the joint, it is necessary to disassemble the drive shaft.



6. Remove the drive shaft (see Section 2).

7. Release the retaining straps and slide the boot off the damaged joint.

8. Using a screwdriver or snap ring pliers, loosen the hinge retaining ring (see accompanying illustrations).





9. Using a soft-faced hammer, knock the joint off the shaft.

10. Install a new snap ring into the groove of the new joint.

11. If dirt is found in the lubricant, for example as a result of damage to the protective cover, completely remove the old lubricant and wash the joint in gasoline.

Caution: Even a small amount of dirt can cause the joint to break!

Lubricate the joint with the required type of grease (for example LM 47 Liqui Moly) as shown in the accompanying illustration or with a wooden spatula. Press the joint onto the shaft until the locking ring snaps into place using a soft-faced hammer.

12. Fill the boot with the remaining grease, pull it over the hinge and secure with bandage straps (see Section 5).

13. Install the drive shaft on the vehicle (see Section 2).
