Tools You'll Likely Need:
* Jack and jack stands: Essential for safety. Never work under a car supported only by a jack.
* Wheel chocks: To secure the other wheels.
* Lug wrench: To remove the wheel.
* Torque wrench: Absolutely crucial for proper tightening.
* Hammer and punch (or drift punch): For removing and installing components.
* Socket set and wrenches: Various sizes will be needed.
* Bearing packing tool (optional but helpful): For repacking the bearings with grease.
* Penetrating lubricant (like PB Blaster): To help loosen seized bolts.
* Clean rags and shop towels: To keep things clean.
* New front wheel bearings and seals (get the correct ones for your car): Get these *before* you start.
* Possibly a press (depending on the type of bearing and your comfort level): Some methods avoid a press entirely.
* A repair manual for your specific year and model Firebird: This is vital.
General Steps (This is a simplified overview; consult your manual):
1. Safety First: Park on a level surface, engage the parking brake, and chock the rear wheels. Jack up the front of the car and securely support it on jack stands.
2. Remove the Wheel: Remove the lug nuts and the wheel.
3. Remove the Brake Caliper: Unbolt the brake caliper and carefully hang it out of the way using a wire or bungee cord. Do not let the brake line hang freely; support it.
4. Remove the Rotor: Remove the rotor. This may require some persuasion with a rubber mallet if it's stuck.
5. Remove the Axle Nut: This is usually a large nut on the end of the axle. You'll likely need a breaker bar or impact wrench to loosen it. Note its position and orientation before removing it completely. This is important for proper reassembly.
6. Remove the Hub Assembly: This is where things get more complex. The hub assembly (which contains the bearings) may be held on by various bolts or a large nut. Your repair manual will show you the specific method for your car. This might involve removing cotter pins and using a puller.
7. Press Out the Old Bearings (If necessary): Depending on the hub design, you may need to press the old bearings out of the assembly using a bearing press. Some designs allow for simpler removal.
8. Clean Thoroughly: Clean all parts of the assembly, removing any old grease or debris.
9. Install the New Bearings and Seals: Pack the new bearings with grease (if necessary – some are pre-packed). Install the new bearings and seals using a press if necessary, or follow the method described in your repair manual.
10. Reassemble Everything: Reinstall the hub assembly, rotor, caliper, wheel, and lug nuts. Torque everything to the correct specifications as stated in your repair manual. This is critically important for safety and proper operation.
11. Lower the Car and Test: Carefully lower the car and test the brakes and steering.
Important Considerations:
* Bearing Type: There are different types of wheel bearings (e.g., tapered roller, ball bearings). The replacement bearings must be the correct type for your vehicle.
* Pre-Loaded Bearings: Some hub assemblies have pre-loaded bearings which simplifies the installation.
* Torque Specifications: Incorrect torque can lead to premature bearing failure or damage to other components. Use a torque wrench and follow your manual's specifications precisely.
* ABS Sensor: If your Firebird has anti-lock brakes (ABS), there will be an ABS sensor on the hub assembly. Be careful not to damage it during the process.
This is a significant repair. If you're not comfortable working on your car, take it to a qualified mechanic. Improperly installed wheel bearings can be extremely dangerous. Remember to always prioritize safety.
