After rebuilding my tr6 diff with new bearings and seals and hoping that I had got the various preloads and contact pattern right,it seems that I hadn't as the diff is now howling at speeds above 30mph,and does it when both accelerating and decelerating. When my depression eases I intend removing the b*****d again and give it one final chance to behave, otherwise I`ll have to exchange it for a recon one. What does anyone think of the contact pattern images, I thought that they were ok
