Here's a general overview of the process. Specific steps may vary slightly depending on which wheel bearing (front or rear) you're replacing. Always consult a repair manual specific to your 2004 Chrysler Concorde for precise instructions and torque specifications.
Tools You'll Likely Need:
* Repair manual: Absolutely essential for specific instructions and torque specs.
* Jack and jack stands: Safety first! Never work under a car supported only by a jack.
* Lug wrench: To remove the wheel.
* Wheel chocks: To prevent the car from rolling.
* Socket set and wrenches: Various sizes will be needed.
* Ball joint separator: To separate the ball joint from the control arm (front).
* Tie rod end separator: To separate the tie rod end from the steering knuckle (front).
* Hammer and punch: Possibly needed to help remove components.
* Press or bearing puller: Essential for removing and installing the bearing. A press is preferred; a puller can damage the hub.
* Torque wrench: Crucial for tightening bolts to the correct specifications.
* Penetrating oil: To loosen rusted or seized bolts.
* Grease: For the new bearing.
* New wheel bearing: Make sure you get the correct part for your vehicle.
General Steps (Front Wheel Bearing - More Complex):
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks on the wheels opposite the one you're working on. Raise the vehicle securely using the jack and jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Disconnect Brake Caliper: Carefully support the caliper with a bungee cord or wire to prevent it from hanging by the brake line. Then, remove the caliper mounting bolts and set the caliper aside.
4. Disconnect Ball Joint and Tie Rod End (Front Only): Use the ball joint separator and tie rod end separator to safely disconnect these components from the steering knuckle.
5. Remove the Brake Rotor (Front Only): Remove the brake rotor.
6. Remove the Hub Assembly: This often involves removing several bolts holding the hub to the steering knuckle (front) or other related components.
7. Press Out the Old Bearing: This requires a hydraulic press or a bearing puller. Use caution to avoid damaging the hub or surrounding components.
8. Press In the New Bearing: Carefully press the new bearing into the hub using the press. Ensure it's seated correctly and evenly.
9. Reassemble: Carefully reverse the disassembly steps, ensuring all components are properly seated and torqued to the specifications in your repair manual. Pay close attention to the correct order and torque specifications for all bolts. Lubricate the new bearing with grease as required.
10. Lower the Vehicle: Carefully lower the vehicle and check for proper wheel alignment.
11. Test Drive: After reassembly, carefully test drive the vehicle to ensure the new bearing is functioning correctly. Listen for any unusual noises.
Rear Wheel Bearing (Generally Simpler):
The process for the rear wheel bearing is generally less complex than the front, as it often doesn't involve disconnecting ball joints and tie rod ends. However, you'll still likely need a press or puller to remove and install the bearing. Consult your repair manual for the specific steps.
Important Considerations:
* This is a simplified overview. Consult your repair manual for detailed instructions specific to your 2004 Chrysler Concorde.
* Incorrect installation can lead to serious damage or injury. If you are not comfortable with this repair, take your car to a professional mechanic.
* Always use the correct parts. Use only high-quality replacement wheel bearings from a reputable supplier.
* Torque specifications are crucial. Using a torque wrench is essential to avoid over-tightening or under-tightening bolts.
This detailed guide provides a framework. Remember to always prioritize safety and consult your repair manual. Improper repair can lead to accidents. If you're unsure about any step, seek professional help.
