As a new member, first of all warm greetings to everyone. I come from the Oberbergischen. If it is time and my own fortune allow, I screw my Jeep myself. My age (over 450,000 km) runs like a clockwork, but the tooth of time just gnaws at the wear parts. I gave my thick new brake discs and rear new wheel bearings. Came such a uniform grinding noise from the rear axle (the faster the louder). Only the grinding noise was not gone! It took only seconds to locate the source of noise – the differential. Which bearings in the differential are probably affected? Are there still free workshops that dare to do so? This goes beyond my screwdriver capabilities. Extension should still be possible, but installation with housing should not spread and set up bearings certainly. I am grateful for every good tip.
