Since I lack the technical and mechanical capability to screw in a lightbulb, the time has come that I seek your assistance. Differential, e36. Its loud. Only intermittenly, and at low speeds, but its loud. WTF can I do about this, without having some greasy schmuck installing a competely new differential and robbing me blind?
Ive heard heavy oil sometimes does the trick, but I cant find ANY on this side of the pond. Any assistance provided would be greatly 'preciated..
Also, is the gear oil easy to replace?
