Here's a general outline of the process. This is not a comprehensive guide and may not cover all variations or unexpected issues. Always consult a repair manual specific to your 1995 Buick Riviera for detailed instructions and torque specifications.
Tools you'll likely need:
* Jack and jack stands: Absolutely crucial for safety. Never work under a vehicle supported only by a jack.
* Wheel chocks: To secure the front wheels.
* Lug wrench: To remove the wheels.
* Socket wrench set: Various sizes, including likely a 15mm, 18mm, and possibly others depending on your specific model.
* Wrench set: May be needed for certain fasteners.
* Shock compressor: Highly recommended to compress the shock and prevent it from springing unexpectedly. Improper compression can be dangerous.
* Penetrating oil (like PB Blaster): To loosen rusted or stuck bolts.
* Torque wrench: For proper tightening of bolts to prevent damage.
* Safety glasses and gloves: Protect yourself from injury.
General Steps:
1. Safety First: Park on a level surface, engage the parking brake, and chock the front wheels.
2. Raise the Vehicle: Securely lift the rear of the vehicle using the jack and place it on jack stands. Ensure the vehicle is stable and safe before proceeding.
3. Remove the Wheel: Remove the lug nuts and take off the wheel.
4. Locate the Shock Absorber: The shock absorber will be attached to the vehicle's body and the rear axle or control arm. You'll likely see the top and bottom mounting points.
5. Disconnect the Shock Absorber: This is where the specifics get tricky, and your repair manual is vital. You'll likely need to:
* Remove the bottom mounting bolt(s): This might require a wrench and possibly a socket. Penetrating oil may be needed.
* Disconnect the top mounting: This is often a nut or bolt on the top of the shock absorber. It might involve removing a retaining clip or other components. The shock might be attached with a bushing or other mountings that need to be carefully removed. This step is highly variable depending on the Buick Riviera's design.
6. Compress the Shock: Use the shock compressor to compress the shock absorber. This makes removal and installation much safer and easier.
7. Remove the Old Shock Absorber: Carefully remove the old shock absorber.
8. Install the New Shock Absorber: Reverse the removal process to install the new shock absorber. Remember to use the shock compressor to compress the new shock during installation.
9. Reconnect Everything: Ensure all bolts and connections are securely tightened to the correct torque specifications (check your repair manual).
10. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
11. Reinstall the Wheel: Reinstall the wheel and tighten the lug nuts.
12. Check for Leaks: Inspect the new shock absorber for leaks.
13. Test Drive: Take a test drive to ensure the new shocks are functioning correctly.
Important Considerations:
* Repair Manual: Obtain a repair manual specific to your 1995 Buick Riviera. This will provide detailed diagrams and instructions crucial for successfully completing this repair.
* Parts: Ensure you purchase the correct replacement shocks for your specific model.
* Torque Specifications: Always tighten bolts to the manufacturer's specified torque. Over-tightening can damage parts.
* Safety: This is a potentially dangerous job. If you're unsure about any step, seek professional help.
This is a general overview. The actual process might vary slightly depending on your specific vehicle's configuration. Always consult your repair manual for detailed, accurate instructions. If you're not comfortable performing this repair yourself, take it to a qualified mechanic.
