Things You'll Need:
- Car lift
- Safety glasses
- 1/2-inch drive impact gun
- 1/2-inch drive impact socket set
- 1/2-inch drive impact spindle lock nut socket
- 1/2-inch drive impact universal swivel
- Impact hammer and bits
- Hand wrench set
- Pry bar
- Metal wire hook
- Screwdrivers
- Rubber mallet
- Lubricant spray
- Angled die grinder with coarse reconditioning discs
- Replacement bearing assembly
-
Step 1
Place the Transport on a car lift to suspend the wheels. The car should be in neutral with the ignition key off.
-
Step 2
Remove the hub cap of the wheel you're replacing the bearing on.
-
Step 3
Put on the safety glasses and remove the wheel nuts using the impact gun and a socket. Remove the wheel.
-
Step 4
Locate the ABS wire and disconnect it from the retainers attached to the strut, front frame and wire harness plug. Unplug the wire from the wire harness.
-
Step 5
Insert the pry bar into the front port hole of the caliper and pry the outboard pad against the rotor to compress the caliper piston enough to allow back and forth movement of the caliper on the slides.
-
Step 6
Remove the caliper anchor bolts using the impact gun and a socket. Use the swivel if necessary to access the upper anchor bolt. Remove the caliper assembly and support it to the coil spring with the metal wire hanger out of the way.
-
Step 7
Remove the rotor. If necessary, spray lubricant on the hub connection of the rotor to the hub assembly and strike the plate of the rotor with a rubber mallet to remove it. Clean the inside surface of the rotor hub using the angled die grinder and a reconditioning disc to remove any rust or corrosion buildup. Set the rotor aside.
-
Step 8
Remove the spindle lock nut with the impact gun and spindle lock nut socket.
-
Step 9
Tap on the spindle of the CV shaft spindle to separate it from the hub assembly. You do not have to remove the CV shaft spindle from the hub assembly. Just get the connection to separate and allow the shaft spindle to move in and out of the hub assembly freely.
-
Step 10
Remove the three hub bearing assembly retaining bolts located on the back of the knuckle. Use the impact gun and a socket with the swivel if necessary. To get the socket onto the bolt heads, manipulate the outer CV shaft inward away from the knuckle.
-
Step 11
Use the impact hammer and a bit to loosen the old bearing assembly. Be careful not to strike the knuckle. Place the bit on the edge of the hub bearing outer flange and use the impact hammer to move it back and forth. Spray lubricant inside the knuckle where the assembly connects to help separate the bearing from the knuckle. Once the bearing has moved away from the knuckle enough, use the impact hammer on the exposed rear flange and hammer the bearing outward. Remove the bearing. Remove the backing plate.
-
Step 12
Clean the surface of the knuckle that the bearing sits against using the die grinder and reconditioning discs. Clean any rust and corrosion from the knuckle. Clean both sides of the backing plate with the die grinder and reconditioning discs.
-
Step 13
Install the new bearing and the backing plate onto the drive shaft spindle. Make sure to insert the ABS wire in through the hole in the knuckle. Press the bearing assembly on by hand (making sure it's aligned properly to the bolt pattern on the knuckle) far enough to thread the retaining bolts through the back of the knuckle and into the bearing. Tighten the bolts alternately using a ratchet and socket to draw the bearing in evenly to the knuckle.
-
Step 14
Replace the spindle lock nut onto the drive shaft spindle and tighten.
-
Step 15
Replace the rotor, the caliper assembly and the caliper anchor bolts and tighten.
-
Step 16
Reattach the ABS wire to the retaining clips and plug the wire back into the wire harness plug.
-
Step 17
Replace the wheel and the wheel nuts and tighten the wheel nuts.
