My ride seems to enjoy crushing 8.8 carrier bearings under hard acceleration. The car originally had a stock 28-spline 8.8 housing and cover with 3.55 rear gears. The 1st time it occurred, I was climbing a mountain at close to full throttle - rear end started whining under all conditions. I installed a TA Performance girdle cover after replacing the bearings and not long after, I crushed another set of carrier bearings, indicated by the same whining. I eventually had a shop perform some work on my stock housing - straightened and welded the tubes, gusseted a few spots, upgraded to Superior Gear 31-spline axles, dropped down to 3.31 rear gears, and a Detroit Truetrac diff. Still running the TA Performance girdle cover. Is there anything else I can do to beef it up?
