Four post car lifts
Position the vehicle on a lift so that the front and rear of the vehicle are equidistant from the ends of the lift. Chock the wheels, put the transmission in neutral and apply the parking brake if possible.
If free wheel rotation is required, use an appropriate lift that supports the vehicle under the axle housings.
Two post car lifts
WARNING: After reaching the desired height, make sure the vehicle is stable before starting work.
WARNING: If it is necessary to disengage the axle shafts, release the parking brake and select a neutral position on the transmission so that after the vehicle has been raised to the desired height, the axle shaft (And) could rotate.
- Position the vehicle so that the center of the lift struts is aligned with the front of the driver/passenger seat cushions.
- Extend the lift arms and position the pads of each lift arm under the lift points on the body side members marked with arrows in the illustration.
- Raise the vehicle just enough to raise the wheels and check that the pads of each lift arm are still properly positioned and in full contact with the body side members.
- Raise the vehicle to the desired height.
- Make sure the vehicle is properly positioned on all four lift platforms, the platforms are still correctly positioned and in good contact with the body side members.
Four-wheel roller test
WARNING: DO NOT attempt to turn individual wheels while the vehicle is supported on jacks or stands.
If the front and rear rollers rotate at the same speed, and the normal workshop safety requirements are met, then there are no speed limits for testing, except for tire restrictions.
Two-wheel roller test
IMPORTANT: If possible, use a four-wheel roller stand to test the brakes.
If it is necessary to test the brakes on a two-wheel roller stand, it should be done with the driveshaft to the fixed axle removed and the main gearbox and transfer case in neutral. When checking the brakes, allow the engine to idle to maintain vacuum in the brake booster.
