Thread: convert 4 bolt diff to 3 bolt.

Well I have it in and running, nice to have my truck back.

this diff is noisier then befor.

Fine under power then when I take my foot off and a rolling then i get the whine noise.

I have replaced the side bearings, there is no play in the pinion bearings so I didn't bother changing them The diff centre was in alot better condition the the one I took out.

Have I set it up wrong?

any clues?

Matt

any one got any clues where my whine is coming from?
