Introduction
Removing the wheel and releasing the hub allows access to the wheel-side CV joint. After removing the old gaiter and cleaning, the joint is greased and the new gaiter put in place.
Parts
-
-
A jack and a jack stand can be used to raise the affected wheel. The opposite wheel on the rear axle must be chocked for safety.
-
-
-
The cardan nut or transmission nut is located in the middle of the wheel.
-
The nut is braked by a folded collar which is lifted using a chisel
-
It must be loosened with a suitable extension and socket.
-
-
-
The wheel is lifted off the ground using the jack and the car is secured with a jack stand.
-
We can see the torn bellows which must be replaced quickly otherwise the universal joint will wear out.
-
Wheel removal required to access the hub.
-
-
-
In order to release the universal joint from the hub, you must remove the steering ball joint with an extractor.
-
First, remove the 17 nut. Then be careful not to twist the ball joint by forcing it straight with the extractor.
-
-
-
In the same way, remove the upper ball joint.
-
The cardan shaft can now be released from the hub by pushing the latter outwards.
-
Do not pull too hard on the universal joint so as not to disengage it from the differential.
-
-
-
Remove the old bellows and grease
-
To facilitate the installation of the new bellows, the universal joint must be opened in two using circlip pliers.
-
-
-
After complete cleaning, apply new grease to the universal joint.
-
-
-
Put on the new bellows with its clamps
-
First the small side, then lock the cardan joint previously removed by clipping it. Just push it onto its axis.
-
Then we can put on the large side of the bellows and position the clamps.
-
-
-
Install the clamps, ensuring the bellows is correctly positioned.
-
-
-
Insert the universal joint into the hub, reposition the two ball joints by fitting them in with a light hammer blow. Then tighten the 17 nuts.
-
-
-
Reposition the wheel, tighten the wheel by placing it on the ground
-
the transmission nut is tightened last with the extension
-
The nut will be tightened as in disassembly: by giving a light blow with a chisel on the collar in order to fold it into the groove of the universal joint.
