This is a guide to replacing a CV boot on the front axle.
No responsisbilty is accepted for anyone attempting this procedure by following the steps contained in these pages. This is intended as a guide only and all usual precautions should be heeded when attempting work on a motor vehicle. I cannot be held responsible for any damage sustained as a result of using these pages.
Tools needed are as follows:
1. 27 mm socket + ratchet / extension bars
2. 17 mm socket
3. ball joint seperator
4. cv joint clip pliers
5. Torque Wrench
A CV boot kit 441 498 203 A contains the necessary parts for this job. A ball joint pinch bolt lock nut is also required.
Use a flat bladed screwdriver to remove the alloy wheel
centre cap and place to one side.
Use the 27mm socket to loosen the centre bolt.
This bolt will be very tight and must be done with the car on the ground.
Loosen the wheel nuts using a 17mm socket
with extension bar. Raise the car with a
jack and secure on stands. Remove the wheel.
To remove the driveshaft from the strut, it is necssary
to drop the ball joint from the strut housing.
Undo the pinch bolt arrowed (1) and use a ball joint
seperator to drop the ball joint. The strut
can be pulled outwards and push the driveshaft through.
The old bolt can be tightened on to the end of the cv joint.
This will force the joint off the driveshaft.
The old clip should be cut off and the damaged boot and clip
should be discarded.
The groove arrowed on the driveshaft is for the
retaining circlip. The old one should be removed
and the new one from the kit fitted.
Slide the new boot over the shaft and push
the CV joint onto the splines. Use a block
of wood and tap the end of the cv joint
until it locks into place on the circlip.
Pack the boot (50g) and joint (40g) with
grease from the supplied pack.
Pull the boot over the edge of the cv joint
and secure with the supplied clips. The clips
should be tightened using special pliers (I used
a pair of tile cutters).
The driveshaft should be re inserted into the strut and held with the new M16 bolt.
Do not attempt to tighten the M16 driveshaft bolt with the car off the ground.
Lift the ball joint into the slot in the strut base and secure with the pinch
bolt - note the head of the pinch bolt should face in the direction of travel.
Refit the wheel and lower the car to the ground. Tighten the centre bolt as per
specifications in the table below.
The following specifications apply:-
|Ball joint pinch bolt||50 Nm|
|Driveshaft centre bolt||200 Nm + 90 degrees|
|Wheel bolts||110 Nm|
