Single throttle lift-off clunking noise from the side shaft when moving off (audible at the outboard end). The clunk is heard once when changing from forward to reverse (and vice versa).

Note: Sound file in attachment

If the complaint is eliminated by experimentally loosening the outboard collar nut (by 1 turn), the problem is due to micromovement in the connection 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 and must be tightened to the specified torque.

Coat contact surface of side shaft with wheel bearing with Molykote paint. To do this, proceed as follows:

1. Remove outboard side shafts (extract outer joint gearing from wheel hub)

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.
