REMOVAL & INSTALLATION
See Figures 1, 2, 3 and 4
If wheel bearing adjustment will not eliminate looseness or rough and noisy operation, the hub and bearings should be cleaned, inspected and repacked with lithium base wheel bearing grease. If the bearing cups or the cone and roller assemblies are worn or damaged, they must be replaced as follows:
Sodium based grease is not compatible with lithium based grease and the two should not be mixed. Do not lubricate the front and/or rear wheel bearings without first identifying the type of grease being used. Use of incompatible wheel bearing lubricant could result in premature lubricant breakdown and subsequent bearing damage.
- Raise the van until the tire clears the ground. Install a jackstand for safety, then remove the front tire.
- Remove the brake caliper from the spindle as described in Brakes , then wire it to the underbody. Do not let the caliper hang by the brake hose.
- Remove the grease cup from the hub. Remove the cotter pin, castellated retainer, adjusting nut and flat washer from the spindle. Remove the outer bearing cone and roller assembly.
- Pull the hub and rotor assembly off the spindle.
- Place the hub and rotor on a clean workbench, with the back side facing up, and remove the grease seal using a suitable seal remover or small prybar. Discard the grease seal.
- Remove the inner bearing cone and roller assembly from the hub.
- Clean the inner and outer bearing cups with solvent. Inspect the cups for scratches, pits, excessive wear and other damage. If the cups are worn or damaged, remove them with a bearing cup puller (T77F-1102-A or equivalent) as illustrated.
- Wipe all old lubricant from the spindle and the inside of the hub with a clean rag. Cover the spindle and brush all loose dirt and dust from the dust shield. Remove the cover cloth carefully to prevent dirt from falling on the spindle.
- If the inner or outer bearing cups were removed, install replacement cups using a suitable driver tool (T80T-4000-W or equivalent) and bearing cup replacer. Make sure the cups are seated properly in the hub and not cocked in the bore.
- Thoroughly clean all old grease from the surrounding surfaces.
- Pack the bearing and cone assemblies with suitable wheel bearing grease using a bearing packer tool. If a packer tool is not available, work as much grease as possible between the rollers and cages, then grease the cone surfaces.
- Place the inner bearing cone and roller assembly in the inner cup. Apply a light film of grease to the lips of a new grease seal and install the seal with an appropriate driver tool as illustrated. Make sure the grease seal is properly seated and not cocked in the bore.
- Install the hub and rotor assembly on the spindle. Keep the hub centered on the spindle to prevent damage to the retainer and the spindle threads.
- Install the outer bearing cone and roller assembly (after being fully greased) and the flat washer on the spindle, then install the adjusting nut finger-tight. Adjust the wheel bearing. For more details, refer to Routine Maintenance .
- Install the caliper onto the spindle. For more information, refer to Brakes .
- Install the front wheel, then lower the van and tighten the lug nuts to 85-;115 ft. lbs. (115-155 Nm). Install the wheel cover.
- Repeat steps 1-16 for the other front wheel if needed.
- Before moving the van, pump the brake pedal several times to restore normal brake travel.
