[QUOTE="tom'scobra, post: 11866147, member: 124672"] revive an old thread. I recently had a 8.8 diff built with all new parts including a Detroit truetrac 31 spline and Motive 3.31 gears. It made so much noise, after 75 miles I had another shop tear it down, install new bearings and a Ford GT500 3.31 gear. It sill made crunching roaring (not whining) noise. I was so frustrated, I bought another 8.8 housing, another truetrac, another Ford GT500 gear set had it all assembled with the best bearings. SAME RESULTS. Not sure what the problem is. Is it just the nature of the truetrac? Or what? Help any suggestions would be GREATLY appreciated. I should define the problem a bit more. When accelerating it's fine, when I maintain speed it's fine, when I just ease off the throttle it begins to roar, groan, crunching noise. I don't have to be turning. [/QUOTE]
