Wheels and Tires: Testing and Inspection

INSPECT FOR WHEEL DAMAGE
Inspect the lug nuts and tighten to 115-142 N.m (85-104 lb-ft).

NOTE: Loose lug nuts can cause shimmy and vibration and may also distort the stud holes in the wheels.

Make sure wheels and hubs are clean. Stones wedged between the wheel and rotor or lumps of mud and grease can unbalance the wheel.

Check for wheel damage. Wobble or shimmy caused by a damaged wheel will eventually damage the bearings. Inspect the rims for dents that could leak air.

Inspect the front hubs and bearings whenever the hubs are removed or at regular inspection intervals.

INSTALL WHEEL
1. Clean all dirt and corrosion from the hub mounting surface and center pilot hole of the wheel. Apply a thin film of Silicone Dielectric Compound D7AZ-19A331-A or equivalent meeting Ford specification ESE-M1C171-A to the axle pilot flange to prevent corrosion.
2. Place wheel on the hub. Install lug nuts. Tighten them alternately to draw the wheel evenly against the hub.
3. Lower vehicle. Tighten the lug nuts to 115-142 N.m (85-104 lb-ft).
