– Swing segment of hub into window of cage.
– Fold hub out from cage.
The balls of each joint belong to one tolerance group. Check stub
axle, hub, cage and balls for small depressions (pitting build-up)
and chafing. Excessive circumferential backlash in joint makes
itself noticed via tip-in shock, in such cases joint should be re‐
placed. Flattening and running marks of balls are no reason to
replace joint.
Assembling
– Press half of the grease into the joint body.
– Insert cage with hub into joint body.
– Note large chamfer at inner diameter of ball hub and large in‐
ner diameter of ball cage, they must point toward drive axle
when installing.
– Press in opposing balls in sequence, during this, previous po‐
sition of ball hub to ball cage and to joint body must be
established again.
– Distribute remaining grease in cover.
– Outer CV joint, installing, refer to
⇒ “6.4 Front Drive Axle, Servicing”, page 104 .
6.6 Small and Large Clamps, Tightening on
Inner or Outer Joint
Instructions only apply to stainless steel clamps.
– Attach Clamping Pliers - VAG1682A- as shown in illustration.
When doing this, make sure that edges of clamping pliers are
seated in corners -arrows B- of clamp.
– Tension clamp by turning spindle with a torque wrench (do not
tilt clamp tool).
Note
♦
A stainless steel clamp must be used due to hardness of CV
boot material (compared to rubber). This clamp can only be
tensioned using Clamping Pliers - VAG1682A- .
♦
Tightening specification: 25 Nm.
♦
Use torque wrench with adjustment range 5...50 Nm (e.g. Tor‐
que Wrench 1331 5-50Nm - VAG1331- ).
♦
Be sure clamp tool spindle thread -A- moves freely. Grease
with MoS
2
grease if necessary.
♦
If the thread is tight e.g. dirty, the required tensioning force for
the hose clamp will not be achieved in spite of correct torque
specification settings.
