If you are getting a sound from your rear wheels like a small jet trying to take off, and it increases with the speed of the vehicle, you may need a new rear wheel bearing.

The rear wheel bearing and hub come as one piece so you do not need to worry about pressing them together. Removal and replacement is easy as long as you have the right tools. You will need a three arm puller to perform this work.

Begin by safely raising and supporting your vehicle. Then remove the rear tires. Please see our article on safely raising and supporting your car. Wear those safety glasses. You will also need to remove the brake caliper and rotor. Please see our article on removing your caliper and rotor for further help.

With the rotor off begin by using a flathead screwdriver and prying off the dust cap (red arrow).

Remove the'mm triple square bolt. It is torqued to'0NM plus'0 degrees, so you will need a breaker bar to remove it (red arrow).

The bolt is the triple square bolt (red arrow).

The bolt is the triple square bolt (red arrow). This bolt is single use only and must be replaced once removed.

Reinsert the bolt back into the bearing carrier to use as a press point for the puller.
Figure 5

Reinsert the bolt back into the bearing carrier to use as a press point for the puller. Only install the bolt approximately an inch back into the carrier so you have room for the bearing to move forward. Use a three arm puller (red arrow) and pull the old hub/bearing off.

The bearing and hub should come right off as one piece (red arrow).

Clean the stub axle and check for any signs of damage (red arrow).
Figure 7

Clean the stub axle and check for any signs of damage (red arrow). If the old bearing was really bad there may be scoring and damage to the axle. Replace as needed. Please see our article on replacing your rear bearing carrier.

If you can, let the bearing sit out in the sun for a little time to warm it up and help it expand.
Figure 8

If you can, let the bearing sit out in the sun for a little time to warm it up and help it expand. Place the new hub/bearing on the stub axle taking care to make sure it is centered. You should be able to push it on far enough so you can thread the new 18mm triple square bolt on. Use the bolt to seat the new bearing and torque to specs. Installation is the reverse of removal.
