Put a new diff mount in today and noticed that I still have a bit of a "clunk" under acceleration. Also recently changed the mustache bar bushings. One thing that made a big improvement was making a bushing for the two bolts that hold the rear of the diff to the mustache bar.

I found some rubber tubing the had the same ID as the studs and cut a piece about 1/4 of inch thick to insulate the part of the stud meets the mustache bar.

Any one have any ideas or a better solution? Just trying to get the diff to move as little as possible, Thanks

I are a relative expert on this subject and know more than i care too. After replacing every stinking bushing from the tranny back and down to the transverse link, I pulled it apart one more time and found a small hairline crack about 2 inches long at the mounting bolt in the crossmember. Welded it and cured the problem. Other forums have another answer you may not have noticed and that is the wallowing (SP) out of tranny mount bolts allowing it to move forward and backward.

good luck, squid
