Here's a general outline of the process. This is NOT a substitute for a proper repair manual; use this only as a general guide. Variations exist depending on the specific Tempo model.
Tools you'll likely need:
* Jack and jack stands: Absolutely essential for safety. Never work under a car supported only by a jack.
* Wheel chocks: To secure the rear wheels.
* Lug wrench: To remove the wheel.
* Socket set and wrenches: Various sizes will be needed, likely including metric sizes.
* Ball joint separator: To separate the ball joint from the control arm.
* Tie rod end separator: To separate the tie rod end from the steering knuckle.
* Hammer and punch: For carefully removing components.
* Bearing press (or improvised press): Essential for pressing the old bearing out and the new one in. Improvising requires careful attention to avoid damaging the hub or new bearing.
* Torque wrench: Crucial for tightening components to the correct specifications.
* Penetrating oil (PB Blaster or similar): Helps loosen rusted or seized components.
* Grease: For the new bearing.
* New front wheel bearings (and any seals required): Get the correct part number from your repair manual or auto parts store, providing your vehicle's VIN.
General Steps (Consult your repair manual for precise details and torque specifications):
1. Safety First: Park on a level surface, engage the parking brake, and chock the rear wheels. Raise the front of the car using the jack and securely support it with jack stands.
2. Remove the Wheel: Remove the lug nuts and the wheel.
3. Disconnect Brake Caliper: Remove the caliper bolts and carefully hang the caliper out of the way using wire or a bungee cord. Don't let the brake line hang freely.
4. Disconnect Ball Joint and Tie Rod End: Use the appropriate separators to separate the ball joint from the control arm and the tie rod end from the steering knuckle. This usually requires careful hammering and may involve some effort.
5. Remove the Hub Assembly: Depending on your Tempo's configuration, the hub assembly might be held on by a few bolts. Remove these bolts. The hub assembly (containing the bearing) should now come off.
6. Remove the Old Bearing: This is where the bearing press is essential. Carefully press the old bearing out of the hub assembly. Be gentle to avoid damaging the hub.
7. Install the New Bearing: Using the bearing press, carefully press the new bearing into the hub assembly. Ensure it's seated properly.
8. Reassembly: Follow the disassembly steps in reverse order, ensuring everything is properly aligned and tightened to the correct torque specifications (from your repair manual). Pack the new bearing with grease.
9. Torque Specifications: Absolutely critical! Use your torque wrench to tighten all components to the manufacturer's specifications. Incorrect torque can lead to premature bearing failure or other damage.
10. Test Drive: After reassembly, test drive the vehicle at low speeds to ensure everything is working correctly before driving at higher speeds. Listen for any unusual noises from the wheel bearing.
Important Considerations:
* Rust and Corrosion: On a 1993 vehicle, rust and corrosion are likely. Penetrating oil will be your friend. Be prepared for some stubborn components.
* Safety: This is a potentially dangerous job. If you're not comfortable with the level of mechanical skill required, take it to a qualified mechanic.
* Repair Manual: This is not a comprehensive guide. A repair manual specific to your 1993 Ford Tempo is indispensable.
This process is a simplification. The actual procedure will be significantly more detailed. Again, obtain and consult a repair manual for your specific vehicle before attempting this repair. Improper installation can lead to serious safety risks.
