Having investigated the metallic clonk my car has started to develop I believe my LSD is need of an overhaul. There is a lot of backlash on the input and play between the 2 output shafts. One output bearing looks like its on its way out so no more thrashing about for me for a while. Can I get the bits to re-build it, is it very hard to do or do you know of anyone who is good at doing this sort of thing at a reasonable cost?
