That said, here's a general overview of the process. Specific steps and tools may vary slightly depending on the year and model of your Lincoln LS. Always consult a repair manual specific to your vehicle's year and model. A Haynes or Chilton manual would be invaluable.
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 prevent the car from rolling.
* Lug wrench: To remove the wheel.
* Torque wrench: Crucial for tightening bolts to the correct specification.
* Socket set and wrenches: Various sizes will be needed.
* Hammer and punch (possibly): May be needed to help seat components.
* Press (recommended): A bearing press is highly recommended for proper bearing installation to avoid damage. Improper installation can ruin a new bearing.
* Bearing race installer/remover (recommended): Tools designed for this purpose will make the job much easier and safer.
* Clean rags and degreaser: To keep everything clean.
* New wheel bearings and seals: Use only high-quality replacement parts.
* Penetrating oil: To help loosen rusted or stuck parts.
General Steps (Consult your repair manual for specifics):
1. Safety First: Engage the parking brake, chock the wheels, and safely lift the vehicle using the jack and jack stands.
2. Remove the Wheel: Remove the wheel using the lug wrench.
3. Remove the Brake Caliper and Rotor: Carefully remove the brake caliper and rotor, securing the caliper out of the way to prevent damage to the brake line.
4. Remove the Axle Flange Nut: This is usually a large nut that requires a significant amount of torque to remove. A breaker bar may be necessary.
5. Remove the Axle Flange: This step might involve removing other components, depending on your Lincoln LS model. Refer to your repair manual for the correct procedure.
6. Remove the Old Wheel Bearing: This is where the bearing press (and possibly race installers/removers) become essential. Trying to remove it with brute force will likely damage the bearing and hub.
7. Clean the Hub: Thoroughly clean the hub assembly to remove any old grease or debris.
8. Install the New Wheel Bearing: Use the bearing press to carefully install the new bearing into the hub. Do this slowly and evenly to avoid damaging the bearing.
9. Install the New Seals (if necessary): Install any new seals required.
10. Reassemble: Reassemble the axle flange, rotor, caliper, and wheel in the reverse order of removal. Make sure to properly torque all bolts according to your vehicle's specifications (found in your repair manual).
11. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
12. Test Drive: Take a short test drive to ensure everything is working correctly. Listen for any unusual noises.
Important Considerations:
* ABS Sensors: The ABS sensor may be integrated into the wheel bearing assembly. Handle it carefully during the process and ensure it's correctly reinstalled.
* Torque Specifications: Always adhere to the manufacturer's torque specifications found in your repair manual. Over-tightening can damage components. Under-tightening can lead to loosening and failure.
* Lubrication: Use the correct type and amount of grease for the new wheel bearings.
Again, this is a general overview. Always consult a repair manual specific to your Lincoln LS. Incorrect installation can lead to serious problems, including wheel failure, which could result in an accident. If you are unsure about any step, seek professional help.
