Here's a general overview of the steps involved. Remember, this is NOT a substitute for a proper repair manual:
Tools You'll Likely Need:
* Jack and jack stands: 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.
* Socket set and ratchet: Various sizes will be needed.
* Torque wrench: Crucial for tightening bolts to the correct specifications.
* Ball joint separator (pickle fork or ball joint press): To separate the ball joint from the steering knuckle. A press is preferred to avoid damage.
* Tie rod end separator: May be needed to separate the tie rod end from the steering knuckle. Again, a separator tool is preferred.
* Brake caliper removal tool (C-clamp or similar): To compress the caliper piston.
* Hammer and punch: Possibly needed for stubborn components.
* Penetrating oil: To help loosen rusted bolts.
* New front wheel bearing: Make sure you get the correct part number for your vehicle.
* Wheel bearing race and seal installer/remover tools: These specialized tools make the job much easier and prevent damage.
* Clean rags and shop towels: Keep your work area clean.
* Safety glasses and gloves: Protect yourself.
General Steps (Consult your repair manual for precise details):
1. Safety First: Park on a level surface, engage the parking brake, and chock the rear wheels. Raise the vehicle using a jack and securely support it with jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Brake Caliper: Remove the brake caliper assembly. You'll likely need to compress the caliper piston to create enough space to remove the rotor. Support the caliper with a wire or bungee cord to keep it from hanging by the brake line.
4. Remove the Rotor: Remove the brake rotor.
5. Disconnect the Ball Joint and Tie Rod End: This is often the most challenging part. Use the appropriate separator tools to disconnect the ball joint from the steering knuckle and the tie rod end from the steering knuckle.
6. Remove the Axle Nut: Remove the large axle nut securing the steering knuckle to the hub.
7. Remove the Steering Knuckle: Carefully remove the steering knuckle from the hub assembly. This might require some gentle persuasion.
8. Remove the Old Bearing: This usually requires specialized tools to remove the old bearing races and the seal.
9. Install the New Bearing: Carefully install the new wheel bearing, races, and seal, using the appropriate tools to prevent damage. Pay close attention to the correct orientation.
10. Reassemble: Reassemble everything in the reverse order of disassembly, making sure to tighten all bolts and nuts to the correct torque specifications as outlined in your repair manual.
11. Lower the Vehicle: Carefully lower the vehicle after reassembly.
12. Torque Check: Double-check all torque specifications after lowering the vehicle.
13. Test Drive: After reassembly, take a short test drive to make sure everything is working correctly. Listen for any unusual noises.
Important Considerations:
* Wheel Bearing Type: There are different types of wheel bearings (sealed units, etc.). Know which type your Prizm uses before purchasing a replacement.
* Pressing Tools: Using the correct bearing race and seal installer/remover tools is crucial to avoid damaging the new bearing. Improper installation can lead to premature failure.
* Torque Specifications: Following the correct torque specifications is vital for safe and reliable operation. Incorrect torque can lead to loose components or damaged parts.
This is a simplified overview. Do not attempt this repair without consulting a repair manual and having the necessary tools and experience. If you're unsure about any step, it's best to take your vehicle to a qualified mechanic. A improperly installed wheel bearing can lead to serious accidents.
