Tools You'll Likely Need:
* Wheel Hub Puller: This is essential to remove the hub assembly.
* Bearing Race and Seal Installer/Remover Set: This set has the tools to carefully remove the old bearing races (inner and outer) and install the new ones without damaging them.
* Socket Set & Wrenches: Various sizes will be necessary for bolts and nuts.
* Hammer & Punch: For carefully driving out components.
* Pry Bar: Might be needed for stubborn parts.
* Torque Wrench: Crucial for tightening bolts to the correct specifications (found in your repair manual).
* Penetrating Oil (PB Blaster or similar): To loosen rusted or seized components.
* Jack & Jack Stands: To safely lift the vehicle.
* Wheel Chocks: For safety.
General Steps (Consult Your Repair Manual for Precise Details):
1. Safety First: Secure the vehicle with jack stands, and use wheel chocks on the remaining wheels. Disconnect the battery's negative terminal.
2. Remove the Wheel and Brake Components: Remove the wheel, brake caliper, rotor, and brake drum (if applicable). This will give you access to the axle hub.
3. Remove the Axle Nut: This will be a very large nut. Use a breaker bar and appropriate socket, applying penetrating oil beforehand if needed. This is crucial—a stuck nut can damage the axle threads.
4. Remove the Hub Assembly: This is where the wheel hub puller comes into play. The puller will separate the hub from the axle. Use caution not to damage the axle shaft.
5. Press Out the Inner Bearing Race: Use the bearing race and seal installer/remover set to carefully press out the inner bearing race from the axle housing. This is a delicate process.
6. Inspect the Axle: Check the axle for damage. Any significant wear or damage necessitates replacing the axle.
7. Install the New Inner Bearing Race: Use the installer from your set to carefully press in the new inner bearing race.
8. Reassembly: This is the reverse process of disassembly. Pay close attention to the order and torque specifications of all bolts and nuts. The repair manual will guide you on proper axle nut tightening procedures (often involving a specific tightening sequence and torque).
Important Considerations:
* Axle Shaft Damage: If the axle shaft is damaged or shows any wear, it must be replaced. Attempting to reuse a damaged axle can lead to catastrophic failure.
* Bearing Selection: Use only bearings and seals that match the specifications for your 1991 Festiva.
* Torque Specifications: Always consult your repair manual for the correct torque specifications for all fasteners. Using the wrong torque can damage components or compromise safety.
Again, a repair manual is absolutely crucial. This is a complex repair that requires specialized tools and knowledge. If you're not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. Improperly installing a wheel bearing can lead to serious consequences, including accidents.
