Differential Assembly: Testing and Inspection
Torsen Type Limited Slip Differential (LSD) Operational CheckThe Torsen type limited slip differential (LSD) distributes optimum power between the two driving axles according to the difference in torque demanded by the driving wheels. Under no circumstances should the engine be started with either wheel raised off the ground, such as using an on-car-wheel balancer or when transporting the vehicle in the event of an accident.
1. Apply the parking brake, and block the rear wheels.
2. Raise the rear of the vehicle, and make sure it is securely supported.
3. With the ignition switch turned to LOCK (0), shift the transmission into 1st gear, and release the parking brake.
4. Rotate either rear wheel by hand, and check that the other wheel rotates in the opposite direction. Check both wheels.
5. If the opposite rear wheel does not rotate, or if you cannot spin the rear wheels at all, the limited slip differential is faulty and should be replaced.
