Here's a general outline of the procedure. This is NOT a comprehensive guide and should not be considered a substitute for a proper repair manual specific to your vehicle. Consult a repair manual (like a Chilton's or Haynes manual) for detailed instructions, torque specifications, and safety precautions.
Tools You'll Likely Need:
* Jack and jack stands: Absolutely essential for safety.
* Wheel chocks: To secure the vehicle.
* Lug wrench: To remove the wheels.
* Sockets and wrenches: A variety of sizes, including metric.
* Ball joint separator: To separate the ball joint from the steering knuckle.
* Pickle fork (use with extreme caution): Another option for separating the ball joint, but can damage the ball joint boot if used incorrectly. A ball joint separator is preferred.
* Press or bushing installation tool: Essential for properly installing the new bushings. A press is ideal, but specialized tools are available for this specific job.
* Hammer (if using a bushing installation tool that requires hammering): Use a mallet or deadblow hammer to avoid damaging parts.
* Penetrating oil (PB Blaster or similar): To help loosen rusted bolts.
* Torque wrench: To tighten bolts to the correct specifications.
* Safety glasses and gloves: Protect yourself from injury.
General Steps (Consult your repair manual for precise details and torque specs):
1. Safety First: Secure the vehicle on jack stands. Never work under a vehicle supported only by a jack. Engage the parking brake.
2. Remove the Wheel and Tire: Remove the wheel and tire from the side you're working on.
3. Disconnect the Sway Bar Link: Disconnect the sway bar link from the control arm.
4. Disconnect the Ball Joint: Use a ball joint separator or pickle fork (carefully!) to separate the ball joint from the steering knuckle.
5. Remove the Upper Control Arm Bolts: Carefully remove the bolts securing the upper control arm to the vehicle frame and the knuckle. Penetrating oil may be necessary.
6. Remove the Old Bushings: This is often the most challenging part. You'll likely need a press or a specialized bushing removal tool to get the old bushings out. Hammering directly on the bushing is generally not recommended.
7. Install the New Bushings: Use a press or bushing installation tool to press the new bushings into place. Ensure they are properly seated.
8. Reassemble: Carefully reassemble the upper control arm, ensuring all bolts are tightened to the manufacturer's specifications using a torque wrench. Reconnect the ball joint and sway bar link.
9. Reinstall Wheel and Tire: Replace the wheel and tire.
10. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
11. Test Drive: After reassembly, perform a test drive to check for any unusual noises or handling issues.
Important Considerations:
* Rust: On a 1993 vehicle, rust is a significant factor. Be prepared for stubborn bolts and potentially damaged parts.
* Press: A press is the best tool for this job. Improper installation can lead to premature bushing failure and compromised handling.
* Repair Manual: Always consult a repair manual specific to your 1993 Chevy Caprice. This is a general overview and may not cover every detail or variation.
* Professional Help: If you're not comfortable performing this repair yourself, consider taking your vehicle to a qualified mechanic.
This job is best done with experience. If you're unsure about any step, seek professional assistance. Improperly installed control arm bushings can compromise your safety and the handling of your vehicle.
