Turn the wheel wrench counterclockwise to loosen
the wheel nuts. Don't remove the wheel nuts yet.
Notice:If your vehicle has QUADRASTEERŸ and
you use a jack to raise the vehicle without
positioning it correctly, you could damage the

vehicle on a jack, avoid contact with tie rods and tie
rod boots.A. Front Location (2-Wheel Drive 1500 Series)

3. Position the jack under the vehicle as shown. If the
¯at tire is on the front of the vehicle (Two-Wheel
Drive 1500 Series vehicles), position the jack under
the bracket attached to the vehicle's frame, behind
the ¯at tire. If the ¯at tire is on the front of the vehicle
(all other models), position the jack on the frame
behind the ¯at tire.
If the ¯at tire is on the rear, position the jack under
the rear axle between the spring anchor and the
shock absorber bracket.

nuts. If you have to replace them, be sure to
get new GM original equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to the
proper torque speci®cation. See ªCapacities
and Speci®cationsº in the Index for wheel nut
torque speci®cation.
Notice:Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque speci®cation. See ªCapacities and
Speci®cationsº in the index for the wheel nut torque
speci®cation.
When you reinstall the regular wheel and tire, you must
also reinstall the center cap. Place the cap on the
wheel and tap it into place until it seats ¯ush with the
wheel. The cap only goes on one way. Be sure to line up
the tab on the center cap with the indentation on the
wheel.

off your vehicle. For the secondary latch to work,
the spare must be installed with the valve stem pointing
down. See ªStoring a Flat or Spare Tire, Jack and
