Once disassembled, the housing was cleaned out with no evidence of major damage or debris.
The old differential, carrier, gears, and caps
And the new goodies. A 3.73:1 ring and pinion set from Motive Gear, and a 28 spline Detroit Trutrac differential to keep both wheels going the same speed when you hit the gas.
The new assembly all assembled with new bearings, all ready to go back into the housing.
New gears installed with pinion depth set and an acceptable pattern on the gears.
