Common symptoms of bad wheel bearings are:
- Whining noise as speed increases.
- Whining when turning (front bearing).
What you will need:
- Park the vehicle on level ground. Block the front wheel using wheel chocks to prevent the vehicle from rolling.
- Loosen the lug nuts.
- Jack up the vehicle and secure it with jack stands. Put the vehicle on a jack stand to support the frame for added safety. Do not rely on the jack alone.
- For rear-wheel and four-wheel drive types, remove the center nut by popping out the nut indent with a flat head screwdriver and a hammer, then turning the nut counterclockwise; you may use a 30,32 or 36mm socket and a breaker bar and/or ratchet handle.
- Loosen the brake caliper bracket by removing two bolts on the back using a 17mm socket.
- Slide the brake caliper away to remove it completely.
- Take extra precautions not to stretch the flexible brake hose.
- Disconnect the electric parking brake by pressing the lock and pulling it.
- Spray penetrating oil on studs to loosen its grip on the rotor and wait for fifteen minutes.
- Put the transmission in neutral, release the parking brake, and rotate the wheel while gently tapping the inner side of the rotor with a rubber mallet. This would loosen the rotor's grip. Caution: The vehicle may roll if not secured properly.
- Remove the rotor completely by hand.
- Put the parking brake in the park position.
- Remove four bearing housing flange retaining bolts using 14mm socket, ratchet wrench, and different extensions (1 to 6 inches).
- Disconnect the bearing from the wheel spline using a center punch tool and a hammer. Avoid hitting the center thread.
- Remove bearing assembly by hand.
- Be careful not to damage the dust shield.
- Prepare the new bearing assembly.
- Take the wheel speed sensor out of the way.
- Install the dust shield.
- Line up and install the bearing assembly on top of the dust shield using the old impression on the dust shield as a guide. It is recommended to install new bolts on the bearing housing flange.
- Install the bolts initially by hand.
- Use a 14mm socket, ratchet wrench, and different extensions to fasten bearing housing flange retaining bolts. Torque to specs. It is recommended to use anti-seize compounds on the threads.
- Reinstall the rotor.
- Reinstall the brake caliper.
- Reinstall brake caliper bracket bolts by hand, then torque to spec.
- Fasten the bolts using a 17mm socket and a ratchet. Torque the bolts to specs.
- Reconnect parking brake electrical connector.
- Reinstall the center nut by hand.
- Fasten center nut using ratchet and 32mm socket.
- Torque to specs, spin 90 degrees, and re-torque. You may put the vehicle in park and have someone press on the brake while applying torque to the nut.
- Using a flat-head screwdriver, tap the nut to lock it on.
- Reinstall the wheel, install lug nuts, remove the jack stands, lower the jack, fasten the wheel's lug nuts.
While not required, it is recommended to perform an all-wheel alignment after replacing the wheel bearing on a Mitsubishi.
