Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety goggles and gloves.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the suspension components.

3. Inspect and Replace Components

Control Arms and Bushings
- Remove the bolts securing the control arms.
- Inspect the bushings; if they are cracked or deteriorated, replace them with new ones.
- Torque the new bolts to the manufacturer's specifications (typically around 60-70 lb-ft).
Shock Absorbers
- Unbolt the top and bottom mounts of the shock absorbers.
- Remove the old shock absorber and replace it with a new one.
- Secure it in place and torque the bolts to the specified values.
Ball Joints
- If play is detected, remove the retaining clips and unbolt the ball joints.
- Replace with new ball joints, ensuring they are properly seated.
- Torque to manufacturer specifications.

4. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Tighten the lug nuts to the specified torque (typically around 80-100 lb-ft).

5. Final Inspection

After replacing components, double-check all bolts and connections for tightness.
Ensure no tools or loose parts are left in the engine bay or around the suspension area.
