Has anyone actually done it? cheers If they are the same sized diff it should be a straight swap of the LSD centre from one to the other. So assuming you have 2x 188's or 210's and not one of each.Just don't loose or muddle-up any of the preload shims from the side bearings, and leave the pinnion alone!!! SRBMW has done it before I believe. Quote Share this post Link to post Share on other sites

Behind the stub axles (6 allen bolts for the CV's) there are the side flanges, a 188 has 6 bolts and the 210 has 8 holding them on. and a 210 "looks" bigger than a 188.This is a 210, also note the drain on the side, not the back.
