1991 318is diff fluid

Having trouble quoting the previous posts...

I've pulled the diff out, cut out the rubber center portion of the mount and then carefully sliced through the diff mount steel sleeve with a hacksaw blade and then used a screw driver to bend it in and comapse it - then, you're golden. Drive the new one in using a vice, hammer, thumbs, throwing it at a wall. Use some dish soap to help it in.

I like Castrol Hypoy C 80w90, which I think is called Axle Limited Slip 80w90 now. No lockup issues or noise ever, even during autocross. No need to put in an additive either.
