Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, and a flashlight.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Raise the Vehicle

Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel on the affected side for better access to the suspension components.

3. Inspect and Replace Components

Inspect Shock Absorbers/Struts:
- Check for leaks or physical damage.
- If damaged, remove the strut assembly by unbolting the top and bottom mounts.
- Replace with new struts, ensuring all mounting bolts are torqued to manufacturer specifications.
Check Control Arms:
- Inspect bushings for cracks or deterioration.
- If worn, remove the control arm by unbolting it from the chassis and suspension.
- Replace with a new control arm and torque bolts to specifications.
Examine Sway Bar and End Links:
- Look for signs of wear on the sway bar and end links.
- If damaged, remove the end links by unbolting them from the sway bar and control arm.
- Install new end links, ensuring they are properly torqued.

4. Reassemble and Lower the Vehicle

Reinstall the wheel and lower the vehicle back to the ground.
Tighten the lug nuts to the manufacturer’s specifications.
