Limited Slip Rear Differential Operation Check

LIMITED SLIP REAR DIFFERENTIAL OPERATION CHECK
A limited slip differential can be checked for proper operation without removing it from the rear axle housing.

Warning:
^ A vehicle equipped with a limited slip differential will always have both wheels driving. If only one wheel is raised off the floor and the rear axle is driven by the engine, the wheel on the floor could drive the vehicle off the stand or jack.





Raise only one rear wheel. Install Torque Tool ST 205-022 on the wheel lugs.
Use a torque wrench with a capacity of at least 271 Nm (200 ft. lbs.) to rotate the axle shaft. Be sure that the transmission is in NEUTRAL, and that one rear wheel is on the floor while the other rear wheel is raised off the floor. The breakaway torque required to start rotation must be at least 27 Nm (20 ft. lbs.). The initial breakaway torque may be higher than the continuous turning torque.
The axle shaft must turn with even pressure throughout the check without slipping or binding. If the torque reading is less than specified, check the differential case.
