clamp a half shaft in a vice
remove a cover
twist the special tool until the CV JOINT is removed from a half shaft

5) remove the internal CV JOINT

 

6) establish a lock ring internal the CV JOINT:
install the hinge against the stop
establish a lock ring
7) establish a convex washer, note its situation
half shafts with the modified hinges of equal angular speeds are established on cars with the 4-speed automatic transmission 097 and the 130 h.p. engine.
8) tighten clips
