Hi guys,
I got my MFactory LSD 7years ago (E92 335i MT). Now, after about 45k km / 30k miles later, the car has strong vibrations on 3rd gear when decelerating (no brakes). The shop says everything looks firm and without plays.. so that the differential seems to blame.
If it turns out they are right.. It will be a disappointment for me as I thought this to last forever.

So it probably is not the differential. The differential nut was damaged during previous install.. it does not hold the shaft nut and it was overtightened, destroying the bearings.
