Here's a general outline. Consult a repair manual specific to your 2004 Chrysler Concorde for precise details and torque specifications. Variations may exist depending on trim level and options.
Tools You'll Likely Need:
* Jack and jack stands: Absolutely essential for safety.
* Wheel chocks: To secure the front wheels.
* Socket wrench set (metric): Various sizes will be needed.
* Ratchet: To work with the sockets.
* Wrench set (metric): For some bolts that might be easier with a wrench.
* Torque wrench: To tighten bolts to the correct specification.
* Penetrating oil (PB Blaster or similar): Helps loosen rusted bolts.
* Large flat blade screwdriver or pry bar (possibly): To help separate parts.
* Spring compressor: This is crucial for safety. Rear struts contain compressed springs under significant tension. Using a spring compressor is vital to avoid injury.
* New strut assemblies: You'll need replacements.
Procedure (General Steps - Consult Your Repair Manual!):
1. Preparation: Park the car on a level surface, engage the parking brake, and chock the front wheels. Raise the rear of the car using the jack and securely place it on jack stands.
2. Remove the Wheel: Remove the wheel from the side you're working on.
3. Disconnect the Brake Line: Locate the brake line connected to the caliper. You might need to use a line wrench or disconnect tool.
4. Disconnect the ABS Sensor (if applicable): Some models have an ABS sensor attached to the strut assembly. Carefully disconnect the electrical connector.
5. Remove the Sway Bar Link: Disconnect the sway bar link from the strut assembly. This usually involves removing a bolt.
6. Remove the Strut Mounting Bolt(s): Locate the bolts that attach the strut to the control arm and the body. These may be difficult to reach. Apply penetrating oil if needed and allow time to soak.
7. Compress the Spring: Using the spring compressor, carefully compress the spring to relieve tension. Follow the instructions for your specific spring compressor precisely. This is where injuries can easily occur.
8. Remove the Strut Assembly: Once the spring is compressed and the bolts are removed, you should be able to carefully remove the entire strut assembly.
9. Install the New Strut Assembly: Reverse the removal process, ensuring the spring is compressed while installing the new strut.
10. Lower the Vehicle: Carefully lower the vehicle and remove the jack stands.
11. Reconnect everything: Reconnect the brake line, ABS sensor, sway bar link, and wheel.
12. Torque Everything: Use a torque wrench to tighten all bolts to the manufacturer's specifications (found in your repair manual).
Important Considerations:
* Spring Compressor: Investing in a good quality spring compressor is essential and worth the cost. Improper use can be extremely dangerous.
* Repair Manual: A repair manual specific to your 2004 Chrysler Concorde is invaluable. It will provide detailed diagrams, torque specifications, and step-by-step instructions.
* Safety: Always prioritize safety. Work in a well-lit area, use jack stands, and be extremely cautious when working with compressed springs. If you're unsure about any step, it's best to seek professional help.
This is a general guide. Consult a repair manual for your specific vehicle before attempting this repair. Improperly performing this task can lead to damage to your vehicle or personal injury. If you're not comfortable performing this repair yourself, consider taking your car to a qualified mechanic.
