AnswerHUB AND BEARING (FRONT)
REMOVAL
NOTE: Replacement of the Unit III front hub/bearing assembly can be normally done without having to remove the steering knuckle from the vehicle. In the event that the hub/bearing is frozen in the steering knuckle and cannot be removed by hand it will have to be pressed out of the steering knuckle. The steering knuckle will require removal from the vehicle to allow the hub/bearing assembly to be pressed out of the steering knuckle. Refer to Front Steering Knuckle in this section of the service manual for the required removal and installation procedure.
Remove the cotter pin, and nut lock from the stub axle Cotter Pin And Nut Lock
Remove the spring wave washer Nut Lock Wave Washer from the end of the stub axle.
CAUTION: Wheel bearing damage will result if after loosening hub nut, vehicle is rolled on the ground or the weight of the vehicle is allowed to be supported by the tires.
With the aid of a helper applying the brakes to keep the front hub from turning, loosen but do not remove the hub nut. The hub and driveshaft are splined together through the knuckle (bearing) and retained by the hub nut.
Raise vehicle on jack stands or centered on a frame contact type hoist. See Hoisting in the Lubrication and Maintenance section of this manual, for the required lifting procedure to be used for this vehicle.

HUB AND BEARING (REAR)
FRONT-WHEEL-DRIVE VEHICLES
REMOVAL
Raise vehicle on jackstands or centered on a frame contact type hoist. See Hoisting in the Lubrication and Maintenance section of this service manual for required lifting procedure.
Remove wheel and tire.
Remove brake drum from hub/bearing.
Remove rear wheel speed sensor from rear hub/bearing Rear Wheel Speed Sensor This will prevent damage to the speed sensor during removal and installation of the hub/bearing. The rear wheel speed sensor bolts to the hub/bearing. It can not be removed unless the speed sensor is removed first.
CAUTION: When working in the area of the rear hub/bearing and when removing it from the rear axle, care must be used so the teeth on the tone wheel are not damaged. Damage to the teeth on the tone wheel will result in false ABS cycling and corrosion of the tone wheel.
Remove the 4 bolts Rear Hub/Bearing Mounting Bolts attaching the hub/bearing to the rear axle.
CAUTION: Corrosion may occur between the hub/bearing and the axle. If this occurs the hub/bearing will be difficult to remove from the axle.

Pounding on the hub/bearing to remove it from the axle will damage the hub/bearing. This damage will result in noise or failure of the bearing.
If hub/bearing cannot be removed from the axle by hand, use Remover Special Tool 8214 Special Tool 8214 Installed and following procedure to press the hub/bearing out of the axle.
Place Special Tool 8214-1 over tone wheel and against cast flange of hub/bearing Special Tool 8214 Installed
Put a dab of grease in the bolt pilot hole on the back of Special Tool 8214-1.
Insert Special Tool 8214-2 into the hole in the bottom of the end casting on the axle Special Tool 8214 Installed Special Tool 8214-2 should be against and supported by the axle plate Special Tool 8214 Installed when pressing the wheel bearing out of the axle. If Special Tool 8214-2 will not fit into the hole in the end casting, file or grind the flashing from the hole until tool fits properly.
Align bolt in Special Tool 8214-2 with pilot hole in Special Tool 8214-1. Tighten bolt against Special Tool 8214-1.
Press hub/bearing out of axle by continuing to tighten bolt in Special Tool 8214-2 against Special Tool 8214-1.
