Tools You'll Need:
* Jack and jack stands: Absolutely crucial for safety. Never work under a car supported only by a jack.
* Wheel chocks: To secure the front wheels.
* Lug wrench: To remove the wheels.
* Socket wrench set: Various sizes, including metric.
* Wrench set: Various sizes, including metric.
* Shock compressor (highly recommended): Makes compressing the shock spring much easier and safer. Improvised methods are risky.
* Penetrating oil (PB Blaster, etc.): To loosen rusted bolts.
* Safety glasses: Protect your eyes.
* Gloves: Protect your hands.
* New rear shocks: Make sure you get the correct ones for your Regal.
* Torque wrench: For proper tightening of bolts.
* Ratchet: Makes things easier.
* Extensions for your ratchet: To reach difficult bolts.
Procedure:
1. Safety First: Park on a level surface, engage the parking brake, and chock the front wheels. This is crucial to prevent the car from rolling.
2. Raise the Vehicle: Safely jack up the rear of the vehicle and securely support it with jack stands under the rear axle. Never work under a car supported only by a jack.
3. Remove the Wheel: Remove the lug nuts and carefully remove the wheel.
4. Access the Shock: Locate the upper and lower shock mounts. You'll likely need to remove some parts to access the shock. This might include:
* Upper shock mount bolts: These might be difficult to reach. Use penetrating oil if needed.
* Lower shock mount bolts: These are usually easier to access. Again, use penetrating oil if necessary.
5. Compress the Spring: This is where the shock compressor comes in. Using a compressor is strongly advised. Improvised methods can be incredibly dangerous. Carefully compress the spring enough to remove the shock.
6. Remove the Old Shock: Once the spring is compressed, carefully remove the old shock absorber from its upper and lower mounts.
7. Install the New Shock: Carefully install the new shock absorber, ensuring it is correctly seated in both the upper and lower mounts. Use the compressor to keep the spring compressed.
8. Release the Spring: Once the new shock is in place, slowly release the spring from the compressor. Be extremely cautious during this step as the spring will exert considerable force.
9. Reassemble: Reinstall the bolts securing the shock in place, and tighten them to the manufacturer's specified torque. (Refer to your repair manual)
10. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts.
11. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
12. Torque Lug Nuts: Finally, torque the lug nuts to the proper specification (check your repair manual).
13. Test Drive: Take a short test drive to check for any unusual noises or handling issues.
Important Notes:
* Consult a repair manual: This is not a substitute for a proper repair manual specific to your 1994 Buick Regal. The exact procedures and bolt locations may vary.
* Safety: Prioritize safety. If you are not comfortable performing this repair, take your car to a qualified mechanic.
* Parts: Ensure you are using the correct replacement shocks for your vehicle.
This is a general guideline. Incorrectly performing this repair could lead to injury or damage to your vehicle. If you are unsure about any step, consult a qualified mechanic.
