Banana skins are supposed to work well...........
Seriously - no thick oil. If it's really noisy then you will need to adjust the mesh of the pinion to the crownwheel. Detailed explanation in the Workshop Manual. But first - check if the pinion nut is TIGHT.

As Mike suggests it's no big deal, they can run for years with a whining back axle. But sawdust if you really are desperate. :lol:
