The hub and wheel bearing unit is serviced as a complete assembly. Replacement of the front drive hub and bearing assembly can be done without having to remove the steering knuckle from the vehicle. However, if the hub/bearing assembly is frozen to the steering knuckle, removal of the steering knuckle is required.
Disconnect the negative battery cable.
Remove the cotter pin from the end of the stub axle. Remove the nut lock and spring washer. With the brakes applied, loosen, but do NOT remove the axle nut and washer with the vehicle still on the ground or damage to the wheel bearing will result.
Raise and safely support the vehicle. Remove the wheel.
Remove the front brake caliper assembly from the steering knuckle assembly and support from the strut assembly using a strong piece of wire.
Remove the front brake rotor from the hub/bearing assembly.
Remove the retaining nut and washer from the halfshaft stub axle.
Remove the ABS wheel speed sensor from the steering knuckle.
Remove the 4 hub and bearing assembly mounting bolts from behind the steering knuckle.
Remove the hub and bearing assembly from the steering knuckle.
Thoroughly clean the mating surfaces of the steering knuckle and the hub and bearing assembly of any foreign material or nicks so the surfaces are clean and smooth.
Install the new hub and bearing assembly and tighten the mounting bolts in a crisscross pattern to 45 ft. lbs. (65 Nm). Be sure the hub and bearing assembly is seated squarely against the front steering knuckle.
Install the disc brake rotor.
Install the brake caliper assembly onto the steering knuckle.
Install the axle washer and nut. Tighten but do not torque.
Install the ABS wheel speed sensor.
Install the wheel and lug nuts. Torque the lug nuts, in sequence, to 95 ft. lbs. (129 Nm).
Lower the vehicle. Do NOT roll the vehicle until the axle nut has been properly torqued or damage to the front wheel bearings will result.
With the vehicle's brakes applied, torque the axle nut to 180 ft. lbs. (244 Nm). Install the spring washer, nut lock and a new cotter pin. Wrap the cotter pin prongs tightly around the axle nut lock.
Reconnect the negative battery cable. Check the wheel alignment.
The hub/bearing assembly is attached to the steering knuckle with four bolts
Removing a hub/bearing assembly
If the hub/bearing is "frozen" to the steering knuckle, separate the ball joint and lightly tap on the hub/bearing from behind
The hub/bearing assembly should free itself from the steering knuckle
If it's four wheel drive, remove the wheel center and the cotter pin and castelated cover on the axle nut. put the wheel back on the car. With the car on the ground, put your socket through the center of the wheel and using a long breaker bar (with the aid of a five foot pipe) break the axle nut free. Remove the wheel, caliper and rotor. Loosen the three twelve point bolts that retain the bearing hub assembly to the steering knuckle and turn them most of the way out. Put an old twelve point socket on them one at a time and hammer them to drive the hub out of the knuckle, using lots of solvent around the perimeter. If the axle tries to follow put the axle nut on it and give it a shot to separate it from the bearing. Once removed, clean all rust from the bore and reverse process using the new hub. Torque on axle nut is 175 foot lbs. if cotter pin does not align properly, turn tighter to align holes, never back off to do that. good luck
Jack up vehicle and support with jack stands Take off wheel remove brake caliper remove caliper bracket remove rotor remove axle retaining nut cotter pin remove axle retaining nut remove axle from output flange pull axle out of vehicle hub and bearing assembly held in by 4 bolts
installation is reverse of removal. You will need to find out the torque specs for the axle retaining nut.
Get out the axle cotter pin on the axle nut. Loosen the Axle nut while the car is on ground. Loosen wheel nuts. Jack up car and place jack stands underneath. Go underneath car and turn the wheel till you can see the pin through the inner part of the axle, which connects to gear box. you have to take out that pin carefully. hammer pin out from unchamfered side. Take off wheel remove the axle nut the plain washer and the conical washer. Now if you don't want to remove the ball joint remove the bolt from the suspension arm, to locate it look at the arm to which the ball joint is connected and trace it to its pivot point. Pull the complete hub axle assembly in a straight direction, which would remove the inner joint from the gear box. Take a rubber mallet and carefully hammer the axle out from the hub. Please remember that when axle is removed the hub and disc may fall off so be careful. Please use new axle nut, plain washer, conical washer and cotter pin during reinstall
