Here's a general overview of the process. Remember, this is *not* a complete guide, and deviations may exist depending on your specific vehicle's configuration:
Tools You Will Likely Need:
* Jack and jack stands: Absolutely essential for safety. Never work under a vehicle supported only by a jack.
* Wheel chocks: To secure the other wheels.
* Lug wrench: To remove the wheel.
* Torque wrench: Crucial for proper tightening of bolts and nuts to prevent damage.
* Socket set: Various sizes, including metric and possibly SAE.
* Hammer and punch: For removing stubborn parts.
* Pry bar: May be needed to separate components.
* Wheel bearing press or suitable alternative: This is often the most difficult part. You might need a puller and installer specific to the bearing. Improvising can damage the hub.
* Penetrating lubricant (PB Blaster or similar): To help loosen rusted or seized parts.
* New wheel bearing: Ensure you get the correct part number for your vehicle.
* Grease: For packing the new bearing.
* Clean rags: To keep things clean.
* Safety glasses and gloves: Protect yourself.
General Steps (Consult your repair manual for specifics!):
1. Safety First: Park on a level surface, engage the parking brake, and chock the rear wheels. Raise the vehicle safely using the jack and secure it on jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Brake Caliper: Remove the caliper bolts and carefully hang the caliper out of the way using a bungee cord or wire. Do *not* let the brake line hang freely.
4. Remove the Rotor: Remove the rotor (brake disc). This may require some persuasion if it's rusted on.
5. Disconnect the ABS Sensor (if applicable): Carefully disconnect the ABS sensor if it's attached to the hub assembly.
6. Remove the Axle Nut: This is often a large nut requiring significant torque to remove. Use a breaker bar if necessary.
7. Remove the Hub Assembly: This step is highly variable depending on your vehicle. You may need to remove cotter pins, separate ball joints, or use special tools to remove the hub assembly from the knuckle. This often involves separating the spindle from the knuckle.
8. Press Out the Old Bearing: This requires a wheel bearing press or a similar tool. Attempting this with improvised methods can severely damage the hub and bearing.
9. Press In the New Bearing: Using the press, carefully install the new bearing into the hub assembly. Make sure it's seated correctly.
10. Pack the New Bearing with Grease: Pack the new bearing with high-quality wheel bearing grease.
11. Reassembly: Carefully reassemble everything in reverse order, paying close attention to torque specifications for all bolts and nuts. This includes the axle nut, caliper bolts, and lug nuts.
12. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
13. Torque Check: After driving a short distance, recheck the torque on all fasteners.
Warnings:
* This is a complex repair. If you're not comfortable with automotive repair, take it to a qualified mechanic.
* Incorrect installation can lead to serious safety hazards. A failed wheel bearing can cause loss of control of the vehicle.
* Torque specifications are crucial. Use a torque wrench and follow the specifications in your repair manual.
* Improvised tools can damage parts. Invest in or borrow the proper tools.
