Step-by-Step Guide:
1. Prepare the Vehicle
- Park the vehicle on a level surface, engage the parking brake, and turn off the engine.
- Loosen the lug nuts on the rear wheel but do not remove them completely.
2. Lift the Vehicle
- Use a jack to lift the rear of the vehicle off the ground and place jack stands securely underneath the vehicle for added safety.
3. Remove the Wheel
- Remove the lug nuts completely and take off the wheel.
4. Remove the Brake Caliper
- Remove the brake caliper mounting bolts and carefully hang the caliper out of the way, taking care not to damage the brake line.
5. Remove the Axle Nut
- Use a socket wrench or impact wrench to remove the axle nut.
6. Detach the Wheel Bearing
- Separate the wheel hub and bearing assembly from the rear axle assembly by gently prying it off with a pry bar or a flathead screwdriver. Take caution not to damage the axle or hub.
7. Remove the Old Bearing
- In some cases, the wheel bearing may be pressed into the hub assembly, while in others, it may be a separate component. If it is separate, simply pry it out of the hub.
8. Check the Axle
- Inspect the axle for any signs of damage or excessive wear. Clean it thoroughly with a wire brush and apply a small amount of grease to prevent corrosion.
9. Install the New Bearing
- Insert the new wheel bearing into the hub/bearing assembly. If the bearing is separate from the hub, it will need to be pressed in. Refer to the manufacturer's instructions for proper installation.
10. Reattach the Assembly
- Carefully slide the wheel hub and bearing assembly back onto the rear axle assembly, ensuring it is seated properly.
11. Replace the Axle Nut
- Thread on the new axle nut and tighten it by hand.
12. Lower the Vehicle
- Use the jack to lower the vehicle back to the ground and remove the jack stands.
13. Torque the Axle Nut
- Tighten the axle nut to the manufacturer's recommended specifications using a torque wrench.
14. Reattach the Brake Caliper
- Reattach the brake caliper to the mounting bracket and secure it with the mounting bolts.
15. Reattach the Wheel
- Place the wheel back on the hub and thread the lug nuts back onto the studs. Tighten the lug nuts in a star pattern to ensure even distribution of force.
16. Test Drive the Vehicle
- Take the vehicle for a short test drive and listen for any unusual noises or vibrations from the rear wheel. If everything is in order, the wheel bearing replacement is complete.
Remember that this guide is general and the steps may vary depending on the vehicle. It is always best to refer to your vehicle's specific service manual for accurate and detailed instructions. If you are unsure or uncomfortable performing this task, it is best to consult a qualified mechanic.
