Here's a general outline of the process. Specific steps and torque specifications will be found in a repair manual specific to your 2002 Lincoln LS. Using a Haynes or Chilton manual is highly recommended.
Tools You'll Likely Need:
* Repair Manual: Absolutely essential for torque specs and detailed procedures.
* Jack and Jack Stands: Safety first! Never work under a car supported only by a jack.
* Wheel Chocks: To prevent the car from rolling.
* Lug Wrench: To remove the wheel.
* Sockets and Wrenches: A variety of sizes will be needed.
* Torque Wrench: Crucial for tightening bolts to the correct specification.
* Hammer and Punch: Possibly needed to help remove parts.
* Bearing Press: This is the most crucial tool. You can't effectively replace the bearing without one. A cheap harbor freight one may suffice, but a better quality one is recommended to avoid damaging the new bearing or hub.
* Penetrating Oil (PB Blaster, etc.): To help loosen rusted or stuck parts.
* Clean rags and shop towels: For cleaning and protecting parts.
* Safety Glasses and Gloves: Protect yourself from injury.
General Steps (Consult your repair manual for specifics):
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels.
2. Remove the Wheel: Loosen the lug nuts before jacking up the car. Jack up the car securely and place it on jack stands. Remove the wheel.
3. Remove the Brake Caliper: Unbolt and carefully remove the brake caliper, supporting it to prevent stress on the brake line. You may need to use a C-clamp or hang it from something.
4. Remove the Rotor: Depending on the configuration, you may need to remove the rotor.
5. Remove the Axle Nut: This is usually a large nut on the axle. You'll likely need a breaker bar and possibly an impact wrench.
6. Separate the Hub and Axle: This is where things get tricky. You'll need to separate the hub assembly from the axle. The method varies depending on the year and model. Your repair manual will detail this.
7. Press Out the Old Bearing: Use the bearing press to carefully press the old bearing out of the hub assembly. Take your time and apply pressure evenly.
8. Press In the New Bearing: Use the bearing press to carefully press the new bearing into the hub assembly. Again, be even and take your time. You need the right size press fit for this.
9. Reassemble: Reassemble everything in reverse order, making sure to follow the torque specifications listed in your repair manual. This includes the axle nut, rotor, caliper, and wheel.
10. Test Drive: After reassembly, carefully test drive the vehicle to ensure the repair was successful. Listen for any unusual noises.
Important Considerations:
* ABS Sensor: The ABS sensor may be attached to the hub. Handle it carefully to avoid damage.
* Seal: There might be a seal on the hub that needs replacing as well.
* Hub Assembly: In some cases, the entire hub assembly might need to be replaced instead of just the bearing. This is often more cost-effective.
This is a simplified overview. You must consult a repair manual specific to your 2002 Lincoln LS for detailed instructions and torque specifications. Failure to follow proper procedures can lead to serious damage or injury. If you're unsure about any step, seek professional help.
