The size of the "26.1.110" tool depends on the diameter of the drive shaft. The inner ring of the bearing must rest on the collar of the tool. Press out the drive shaft (fig. 14.35) from the CV joint. For a hollow shaft, additionally use the "21.2.120" device. Do not disassemble the CV joint.
Note: If it is necessary to disassemble the CV joint, the location of the cage, separator and its housing should be marked with a punch (fig. 14.36).
Check the CV joint for dirt and damage. Loosen the clamps (5 and 6, Fig. 14.37) and slide the boot (arrow) along the splined shaft. Thoroughly clean the assembled CV joint and completely remove the old grease. Put new grease into the CV joint from the repair kit (80 g).
Install a new protective cover on the rear axle side and remove the adhesive tape.
Lubricate the sealing surface of the cover with sealing gel and press it onto the CV joint using a thrust ring. Install the "33.2.100" device onto the shaft (fig. 14.38). Install a new retaining ring. Press the CV joint with cover (3) onto the splined shaft until a distinct click is heard.
Apply grease to the joint. Put the protective cover on the cover (3). Install new fastening clamps, with the clamp of the large clamp being located between the two holes for the CV joint fastening bolts.
