Well I've been running a 4.10 31 spline Detroit in my 85 Bronco with a healthily built
351 W (4bbl, headers, edelbrock performer intake/carb, Crane RV cam, mildly ported, MSD ignition) and a C6 with stock converter turning 36" super swampers for about 6 years now. Last saturday, after making a turn there was a loud KAABANG from the rear end. I thought the driveshaft broke loose again. But I was still able to drive, I locked it in 4wheel and creaped home. When I yanked the diff out last night, I found 4 of the ring gear's bolts were sheared off, 5 or 6 were bent up to 90 degrees. the driver's side bearing cap on the third
member broke out at the center, the diff clamshelled open, the bearing on the driver's side disintigrated.
All in all, a real mess. When I installed everything 6 years ago, I followed all the torque specs and adjustment procedures. If I do this again those ring bolts are getting RED loctite'd.
Just wish I knew what the sequence of events was causing the failure.
Anyone got any ideas?
