Tire Replacement
Tools Required
J 39544-KIT Complete Torque Socket Set - 10 Pieces
Caution
If penetrating oil gets on the vertical surfaces between the wheel and the rotor or drum it could cause the wheel to work loose as the vehicle is
driven, resulting in loss of control and an injury accident.
Notice
Never use heat to loosen a tight wheel. It can shorten the life of the wheel, studs, or hub and bearing assemblies. Wheel nuts must be tightened
in sequence and to the specified torque to avoid bending the wheel or rotor.
Notice
Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. In order to avoid expensive brake repairs, evenly tighten the
wheel nuts to the proper torque specification.
Notice
Removing the wheel may be difficult because of foreign material or a tight fit between the wheel and the hub/rotor. Slightly tap the tire
sidewall with a rubber mallet in order to remove the wheel. Failure to follow these instructions may result in damage to the wheel.
1.
If equipped, remove the full size (Goodyear 17-inch diameter) spare tier from the trunk and remove the core from the valve stem.
2.
Raise the vehicle on a suitable hoist and support as necessary.
Important
It is not necessary to replace the valve stems in this recall.
3.
Remove the center cap and the core from the valve stem on four tire and wheel assemblies.
4.
Loosen and remove the wheel nuts from all four tire and wheel assemblies.
5.
Remove the first tire and wheel assembly from the vehicle and remove any balance weights from the wheel.
Notice
Use a tire changing machine in order to dismount the tires. Do not use hand tools or tire irons alone in order to remove the tire from the wheel.
Damage to the tire beads or the wheel rim could result.
Notice
Do not scratch or damage the clear coating on aluminum wheels with the tire changing equipment. Scratching the clear coating could cause the
aluminum wheel to corrode and the clear coating to peel from the wheel.
Notice
Damage to either the tire bead or the wheel mounting holes can result from the use of improper wheel attachment or tire mounting procedures.
It takes up to 70 seconds for all of the air to completely exhaust from a large tire. Failure to follow the proper procedures could cause the tire
changer to put enough force on the tire to bend the wheel at the mounting surface. Such damage may result in vibration and/or shimmy, and
under severe usage lead to wheel cracking.
Important
Rim-clamp European-style tire changers are recommended.
6.
Use the tire changer in order to remove the tire from the wheel.
7.
If necessary, use a wire brush or coarse steel wool in order to remove any rubber, or corrosion from the wheel bead seats.
Notice
When mounting the tires, use an approved tire mounting lubricant. DO NOT use silicon or corrosive base compounds to lubricate the tire bead
and the wheel rim. A silicon base compound can cause the tire to slip on the rim. A corrosive type compound can cause tire or rim
deterioration.
