Towing or Changing Wheels

Towing, Changing Wheels And Rolling Road/wheel Spinner Test





Towing

CAUTION: All-wheel drive cars must not be towed with only one pair of wheels off the ground. If the car is towed in the wrong way the viscous coupling (which distributes power between the front and rear drive wheels) will be immediately and irreparably damaged. If the car must be moved with the rear or front wheels off the ground the propeller shaft must be disconnected.





Changing Wheels
- All wheel drive cars have an extra jacking point. This is located just in front of the rear axle, see illustration. The jacking point has a mounting for the cars jack and a plate for a garage jack or pillar lift. Use the correct jacking points and ensure that lifting equipment does not damage the fuel tank.

WARNING! All-wheel drive cars must have the same size of wheel all round. A spare wheel of the 'Temporary spare" type must only be used with T125/90 R15 size wheels. Using incorrectly sized wheels can seriously damage the transmission.





Rolling Road Test
- When testing brakes or on a rolling road or wheel spinner or balancing wheels the other wheels must rotate freely, see illustration. Driving power is transferred automatically to the car's other driving wheels by the TRACS system and the viscous coupling.





Tightening Wheel Studs
- This the following applies when installing and tightening wheel studs.
- Ensure that the brake disk and wheel rim mating surfaces are clean. Lubricate hub center rim guide. Use rust inhibitor 1161030-0.
- Tighten studs lightly. Then tighten crosswise to 110 Nm (81 ft.lb.). Torque socket 1158147-7 must be used when tightening with an impact wrench.
- Crosswise tightening and torque tightening is important to prevent tension in the brake disc.

NOTE: The torque socket is designed for tightening wheel studs with a normal pneumatic impact wrench with an output torque of 250-350 Nm (185-259 ft.lb).

Use Of Tensioner 999 5659
Special tools: 999 5659, 999 5660

Use Of Tensioner
- The tensioner is used when working with the suspension where it is vital that the screwed joints to the rubber bushings are tightened in the normal position, that is to say in the same position as when the car is on the ground.
- The tensioner off-loads pressure on the components in the suspension when removing/installing. The tool is mounted on the rear axle member with a mounting 999 5660. This means that the lift stability is not affected during work.





Install mounting and tensioner
- Install the long screw in the mounting.
- Install mounting 999 5660 on rear axle member.

NOTE: Ensure that the tool's mating surfaces with the rear axle member are clean.

- Install tensioner 999 5659 in the long screw.





- Ensure that the rollers are in contact with the control arms on both sides, see illustration





- Move control arms to their normal position using the tensioner





Normal Position
- The normal position of the rear suspension is when the distance from fender edge (1) to wheel center (2) is 381 mm (15 in).
