Sound recording of complaint
Cause:
If the complaint is eliminated by experimentally loosening the outboard collar nut (by 1 turn), the problem is due to
cracking of the microweld between the wheel bearing inner race and the joint housing of the side shaft.
Note: The collar nut must always be replaced after being loosened.
Remedy:
Coat contact surface of side shaft with wheel bearing with Molykote paint. To do this, proceed as follows:
1. Remove side shafts
2. Clean contact surface A (see image file in attachment "Outer joint housing before") before coating with Molykote
paint (free of dust and grease)
3. Coat contact surface A (see image file in attachment "Outer joint housing after") with Molykote and leave to dry for
"one hour" in removed condition
4. Reinstall side shafts
Note: Before using low friction paint (Molykote) stir or shake it thoroughly.
