Differential Assembly: Service Precautions

Precautions for Torsen Type Limited-slip Differential (LSD)

^ The Torsen differentials are mechanical limited-slip differential which delivers the available power to the wheels and driveshafts with the most grip or resistance as the engine torque output increases.
^ Do not do repair procedures that require the engine running with one rear wheel raised; such as an on-car wheel balancer.
^ Do not tow the vehicle with the rear wheels on the ground.
^ Never dismantle any part of the differential other than right and left tapered roller bearings.
^ To optimize the Torsen differential, equip your vehicle with rear tires of the same brand, the same size, and with even wear.
