Here's a general overview of the process. Specific steps and tools may vary slightly depending on the exact Stratus model and variations in the year. Always consult a repair manual specific to your year and model for detailed instructions and torque specifications. A Haynes or Chilton manual is a good investment.
Tools You'll Likely Need:
* Jack and jack stands: Absolutely crucial 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.
* Socket set and wrenches: Various sizes will be needed.
* Ball joint separator: To separate the ball joint from the control arm.
* Tie rod separator: To separate the tie rod end from the steering knuckle.
* Hammer and punch (or drift): May be needed for stubborn parts.
* Wheel bearing press: Highly recommended. Improvising can damage the new bearing.
* Torque wrench: Essential for tightening bolts to the correct specifications.
* Penetrating oil (PB Blaster or similar): Helps loosen rusted or seized bolts.
* Grease: For the new bearing.
* New wheel bearing: Make sure you get the correct one for your vehicle.
General Steps (This is NOT a complete guide, consult your repair manual):
1. Safety First: Engage the parking brake, chock the wheels, and jack up the front of the car securely on jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Disconnect Components: You'll need to disconnect the brake caliper, the ABS sensor (if applicable), the ball joint, and the tie rod end from the steering knuckle. This often involves using a ball joint separator and a tie rod separator. Be careful not to damage these components. Support the caliper with a wire or bungee cord to keep it from hanging by the brake line.
4. Remove the Hub Assembly: Once the components are disconnected, you should be able to remove the hub assembly from the steering knuckle. This may require some persuasion.
5. Remove the Old Bearing: This is where a wheel bearing press is essential. Trying to remove it without one can easily damage the bearing and the hub assembly. The press will press the old bearing out.
6. Install the New Bearing: Use the wheel bearing press to carefully press the new bearing into the hub assembly. Ensure it's seated correctly and evenly. Pack the bearing with grease as per the manufacturer's instructions.
7. Reassemble: Carefully reassemble everything in the reverse order of disassembly. Pay close attention to the torque specifications for all bolts.
8. Lower the Vehicle: Lower the vehicle slowly and carefully.
9. Test Drive: Test drive the vehicle to ensure the new bearing is working correctly and there are no unusual noises.
Again, this is a simplified overview. Working on your car's suspension can be dangerous if not done properly. Consult a repair manual for your specific vehicle and if you're unsure about any step, take it to a professional mechanic. Improperly installed wheel bearings can lead to loss of control and accidents.
