It is very important to be careful about running the engine, on vehicles equipped with limited slip differentials, while the vehicle is up on a jack. This is because if the drive train is engaged, power is transmitted to the wheel with the best traction and the vehicle will drive off the jack, resulting in possible damage or injury.
Jack the truck from under the axles, radius arms, or spring hangers and the frame. Be sure and block the diagonally opposite wheel to prevent the vehicle from moving. Place jackstands under the vehicle at the points mentioned above when you are going to work under the vehicle.
When raising the vehicle on a hoist, position the front end adapters under the center of the lower suspension arm or the spring supports as near to the wheels as practical. The rear hoist adapters should be placed under the spring mounting pads or the rear axle housing. Be careful not to touch the rear shock absorber mounting brackets.
