Here's a general overview. Specific steps and torque specifications will vary slightly depending on the exact model and engine of your Grand Am. Always consult a repair manual specific to your 1995 Grand Am for detailed instructions and diagrams. A Haynes or Chilton manual is a good investment.
Tools You'll Need:
* Jack and jack stands: Essential for safety. Never work under a car supported only by a jack.
* Wheel chocks: To secure the other wheels.
* Lug wrench: To remove the wheel.
* Socket wrench set (metric): Various sizes, including those likely needed for the control arm bolts, sway bar link, and possibly the ball joint.
* Ratchet and extensions: For better reach in tight spaces.
* Torque wrench: Crucial for tightening bolts to the manufacturer's specified torque. Incorrect torque can damage the suspension.
* Ball joint separator (pickle fork or ball joint press): To separate the ball joint from the steering knuckle. A press is preferred to avoid damaging the knuckle.
* Penetrating oil (PB Blaster or similar): To loosen rusted bolts.
* Hammer: May be needed to help separate parts.
* New lower control arm: Make sure you get the correct part for your Grand Am.
* Safety glasses and gloves: Always protect yourself.
General Steps (Consult your repair manual for specifics):
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels.
2. Raise and Secure: Safely jack up the vehicle and securely support it on jack stands.
3. Remove the Wheel: Remove the lug nuts and wheel.
4. Disconnect Sway Bar Link: Locate the sway bar link connected to the lower control arm. Use the appropriate socket to remove the nut and bolt, separating the link from the control arm.
5. Disconnect Brake Line (if applicable): Depending on your model, the brake line might be attached to the control arm bracket. If so, carefully disconnect it.
6. Remove ABS Sensor (if applicable): Some models have an ABS sensor near the control arm. Disconnect the sensor.
7. Disconnect Ball Joint: This is often the most challenging part. Use a ball joint separator (preferably a press) to separate the ball joint from the steering knuckle. Penetrating oil will help.
8. Remove Control Arm Bolts: Locate and remove the bolts securing the lower control arm to the frame/subframe. These are usually located at the front and rear of the control arm. Penetrating oil may be necessary.
9. Remove the Old Control Arm: Once the bolts are removed, carefully lower the old control arm.
10. Install the New Control Arm: Install the new lower control arm, ensuring it's properly seated.
11. Reinstall Everything: Reverse the removal steps, carefully installing the bolts, sway bar link, ball joint, etc. Use the correct torque specifications from your repair manual for all bolts.
12. Lower and Check: Carefully lower the vehicle to the ground. Check that everything is tight and secure.
13. Test Drive: Perform a short test drive to check for any unusual noises or handling issues.
Important Notes:
* Alignment: After replacing a lower control arm, you'll almost certainly need a wheel alignment. This is crucial for proper handling and tire wear.
* Rust: On older vehicles, rusted bolts can be extremely difficult to remove. Use penetrating oil generously and allow it to soak for several hours or even overnight.
* Parts: Ensure you purchase the correct replacement lower control arm for your specific 1995 Pontiac Grand Am model.
This is a simplified overview. Again, refer to a repair manual specific to your vehicle for detailed instructions and torque specifications. If you're unsure about any step, it's best to seek professional help. Improperly installing a lower control arm can compromise your vehicle's safety.
