Here's a general outline of the process. Specific steps and torque specifications will vary depending on your exact model and any aftermarket modifications. Always consult a repair manual specific to your vehicle year and engine (e.g., a Haynes or Chilton manual) for detailed instructions, diagrams, and torque specifications.
Tools You'll Likely Need:
* Jack and jack stands: Safety first! Never work under a vehicle supported only by a jack.
* Wheel chocks: To secure the vehicle.
* Lug wrench: To remove the wheel.
* Socket set and wrenches: Various sizes, including metric.
* Ball joint separator: To separate the ball joint from the steering knuckle. A pickle fork can be used, but it risks damaging the ball joint.
* Press or bushing removal/installation tool: This is crucial. Pressing the bushing out and in is the most difficult part and requires specialized tools. Improper methods can damage the control arm.
* Torque wrench: Essential for tightening bolts to the correct specification.
* Penetrating oil (PB Blaster, etc.): To loosen rusted or seized bolts.
* Hammer: Possibly needed for some stubborn components.
* Safety glasses and gloves: Protect yourself.
General Steps (Consult your repair manual for precise details):
1. Safety First: Secure the vehicle with parking brake engaged and wheel chocks. Raise the vehicle safely using the jack and secure it on jack stands.
2. Remove the Wheel: Remove the wheel from the affected side.
3. Disconnect the Sway Bar Link: Disconnect the sway bar link from the lower control arm.
4. Disconnect the Brake Caliper: Support the caliper with a wire or bungee cord to prevent it from hanging by the brake line. You may need to remove the caliper completely, depending on how much room you need.
5. Disconnect the ABS Sensor (if applicable): Carefully disconnect the ABS sensor wire from the control arm.
6. Remove the Ball Joint: Use a ball joint separator to separate the ball joint from the steering knuckle.
7. Remove the Lower Control Arm Bolts: These bolts usually connect the control arm to the frame or subframe. Use penetrating oil if necessary.
8. Remove the Lower Control Arm: Carefully lower the control arm.
9. Press Out the Old Bushing: This requires a press or specialized bushing removal tool. Attempting this without the correct tools risks damaging the control arm.
10. Press In the New Bushing: Use the appropriate press or installation tool to install the new bushing. Make sure it's seated correctly.
11. Reassemble: Reverse the disassembly steps, ensuring all bolts are tightened to the correct torque specifications as indicated in your repair manual. Pay attention to the order of assembly.
12. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
13. Check: Test drive the vehicle carefully to ensure everything is working correctly.
Important Considerations:
* Alignment: After replacing the lower control arm bushings, you'll almost certainly need a wheel alignment. The geometry of the suspension will have been altered.
* Parts: Make sure you purchase the correct bushings for your specific vehicle.
* Press: If you don't have access to a press, consider taking the control arm to a professional shop to have the bushings pressed in and out. This will save you time and potential damage.
This is a simplified overview. Again, consult a repair manual specific to your 2004 Buick Rendezvous before attempting this repair. Failure to follow proper procedures could result in damage to your vehicle or personal injury.
