Circlip

q	Always renew

q	Remove and install using circlip pliers -VW 161 A-

Removing outer constant velocity joint –  Drive joint off drive shaft with a firm blow from an aluminium hammer.

Pressing off inner constant velocity joint   Note! First drive off boot with drift.

Pressing on inner constant velocity joint –  Press on joint as far as stop. –  Engage circlip.   Note! Chamfer on internal diameter of ball hub (splines) must face contact collar of drive shaft.

Tightening hose clip on outer joint –  Apply clamp tensioner -V.A.G 1682- as shown. Ensure jaws of tool make contact with lugs -arrows B- on hose clip. –  Tighten hose clip by turning spindle with torque wrench (take care to keep clamp tensioner straight).   Note! t  Due to the hard material of the CV joint boot (as opposed to rubber), a stainless steel hose clip is required; this can only be tightened using clamp tensioner -V.A.G 1682-. t  Tightening torque: 20 Nm. t  Use torque wrench-C- (adjustment range 5 ... 50 Nm), e.g. -V.A.G 1331-. t  Make sure thread of spindle -A- on clamp tensioner moves freely. Lubricate with MOS2 grease if necessary. t  If the thread is stiff (e.g. due to dirt), the required clamping force will not be attained at the hose clip when applying the specified tightening torque.
