WARNING:
BEFORE
RE-INSTALLING
ALUMINUM WHEELS, ANY BUILD UP OF
CORROSION
ON
THE
WHEEL
MOUNTING
SURFACE
AND
BRAKE
DRUM OR DISC MOUNTING SURFACE
SHOULD BE REMOVED BY SCRAPING
AND WIRE BRUSHING. INSTALLATION
OF ALUMINUM
WHEELS
WITHOUT
GOOD METAL-TO-METAL CONTACT AT
THE
MOUNTING
SURFACES
CAN
RESULT IN LOOSENING OF THE WHEEL
NUTS
WHICH
CAN
EVENTUALLY
ALLOW THE WHEEL TO COME OFF
WHILE THE VEHICLE IS IN MOTION,
CAUSING LOSS OF CONTROL.
Wheels can be hard to remove from the car due to
rusting or a tight fit between the wheel center hole and the
axle or rotor. These wheels can be removed without damage
as follows:
1. Retighten all lug nuts on the affected wheel, then
loosen each nut two turns.
2. Lower vehicle onto floor.
3. Rock the car from "drive" to "reverse" allowing car
to move several feet in each direction. Apply quick, hard jabs
on the brake pedal to loosen the wheel.
4. Raise the car. Remove the lug nuts and the wheel.
Penetrating oil has not been found to be effective in
removing tight wheels. However, if it is used it should be
applied only to the hub surface.

WARNING:
DO
NOT
ALLOW
THE
PENETRATING OIL TO GET ON THE
VERTICAL SURFACES BETWEEEN THE
WHEEL AND THE DRUM (OR ROTOR)
BECAUSE PENETRATING OIL IN THIS
AREA COULD CAUSE THE WHEEL TO
WORK LOOSE AS THE CAR IS DRIVEN
CAUSING LOSS OF CONTROL.
Never use heat to loosen a tight wheel because the
application of heat to the wheel can shorten the life of the
wheel.
Wheel nuts must be tightened in sequence and to proper
torque to avoid bending wheel or brake drum or rotor (Fig.
3E-4).
Tire Mounting and Demounting
Use a tire changing machine to mount or demount tires.
Follow the equipment manufacturer's instructions. Do not
use hand tools or tire irons alone to change tires as they may
damage the tire beads or wheel rim.
Rim bead seats should be cleaned with a wire brush or
coarse steel wool to remove lubricant, old rubber, and light
rust. Before mounting or demounting a tire, the bead area
