Servicing outer constant velocity joint

Boots made of rubber are secured using pliers -V.A.G 1275-.

Instructions apply only to stainless steel clips.

Tightening hose clip on outer joint

–	Apply clamp tensioner -V.A.G 1682- as shown. Ensure jaws of clamp tensioner make contact with lugs -arrows B- on hose clip.

–	Tighten hose clip by turning spindle with torque wrench (take care to keep pliers straight).

t	Tightening torque: 20 Nm.

t	Use torque wrench with 5…50 Nm adjustment range (e.g. -V.A.G 1331-).

t	Make sure thread of spindle 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 the specified tightening torque is applied.

Pressing off outer constant velocity joint

–	Clamp drive shaft in vice using protective jaw covers.

–	Remove the large hose clip and pull back the rubber boot.

–	Screw the spindle -3207- into the joint pin until the constant velocity joint can be detached.

Venting joint boot

Only applies to boots made of rubber:

A partial vacuum is sometimes created in the rubber boot during installation.

This vacuum produces a fold -arrow- when driving.

For this reason, please note the following:

–	Before tightening the hose clips, vent the boot to equalise pressure by briefly lifting the lip.

Installation position of spacer ring and dished spring (outboard end)

1 -	Dished spring

2 -	Spacer ring (plastic)
