Cleaning the parts and inspecting the drive
The outer constant velocity joint should rotate with a slight effort without jerking and jamming, radial and axial play
If there are any, you need to replace the hinge
The inner hinge should move in the angular and axial directions with a slight effort, while jerking, jamming and radial play should not be felt.
Otherwise, you need to replace the hinge
Protective covers of the outer and inner hinges should not have cracks and breaks
The wheel drive shaft must not be deformed. Replace warped shaft
To replace the inner hinge or its cover, we disconnect the clamp of the protective cover with a screwdriver or pliers and remove the clamp
Clamps are disposable, we replace the clamps during assembly
We also remove the second clamp securing the cover
We move the protective cover from the hinge body, remove some of the lubricant from it and mark the position of the hinge relative to its body
Disconnect the inner hinge housing from the drive
Using a puller, we open the retaining ring of the hinge hub and remove the ring, removing it from the groove of the shaft
Remove the hub with rollers from the shaft splines
Remove the protective cover from the shaft
We wash all metal parts with kerosene until the old grease is completely removed
Before assembly, fill the cavity of the body and the cover of the inner hinge with grease in an amount of approximately 150 grams.
One hundred grams in a hinge and 50 grams in a case
In order not to damage the hinge cover during assembly, we wrap the splined part of the shaft with insulating tape
If there is no lubricant recommended by the factory, domestic SHRUS-4 lubricant can be used
We assemble and install the drive in reverse order
