Changing wheels

07

check that the jack is still correctly posi- tioned in the attachment.

7.Raise the vehicle until the wheel to be changed is lifted off the ground.

8.Unscrew the wheel bolts completely and carefully remove the wheel so as not to damage the threads on the studs.

NOTE

To avoid excessive wear and the necessity of rebalancing, mark and reinstall wheels in the same location and position as before removal. To lessen the chance of imbal- ance, each wheel hub is equipped with a guide stud to ensure that a removed wheel can be reinstalled in its original position (as when changing over to winter tires/wheels).

CAUTION

The vehicle must not be driven with wheels of different dimensions or with a spare tire other than the one that came with the vehicle. The use of different size wheels can seriously damage your vehi- cle's transmission.

Correct tightening torque on wheel bolts must be observed.

The wheel bolts should never be greased or lubricated.

Extended, chromed wheel bolts must not be used with steel rims, as they make it impossible to fit the hub caps.

Installing the wheel

1.Clean the contact surfaces on the wheel and hub.

2.Lift the wheel and place it on the hub.

3.Install the wheel bolts and tighten hand- tight. Using the lug wrench, tighten cross- wise until all bolts are snug.

4.Lower the vehicle to the ground and alter- nately tighten the bolts crosswise to 103 ft.lbs. (140 Nm).

5.Install the wheel cover (where applicable).

WARNING

The jack must correctly engage the bar in the jack attachment. The vehicle's weight must not rest on the jack attach- ment. See illustration "Attaching the jack" on the previous page.

Be sure the jack is on a firm, level, non- slippery surface.

Never allow any part of your body to be extended under a vehicle supported by a jack.

Use the jack intended for the vehicle when replacing a wheel. For any other job, use stands to support the side of the vehicle being worked on.

Apply the parking brake and put the gear selector in the (P)ark position.

Block the wheels standing on the ground, use rigid wooden blocks or large stones.

The jack should be kept well-greased and clean, and should not be damaged.

No objects should be placed between the base of jack and the ground, or between the jack and the attachment bar on the vehicle.

The jack and tools should be returned to their storage spaces. The jack should be cranked down fully so that it fits into the intended space.
