General Information

The 42LE uses a hypoid type ring and pinion gear set. The ring gear is bolted to the differential case, and drives the differential case in all gear ranges. The differential case assembly consists of the differential case and within it, two pinion gears, two side gears and a pinion mate shaft retained with a roll pin. The differential case provides input power from the ring gear to the axle shafts through the case, pinion shaft, pinion gears and side gears. The pinion and side gears allow the right and left axles to rotate at different speeds while the vehicle is cornering.
