Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, wheel chocks.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Lift the vehicle and support it with jack stands.

2. Inspect and Replace Suspension Components

Inspect Struts/Shocks:
- Remove the wheel for better access.
- Check for any visible leaks or damage on the struts or shocks.
- If damaged, unbolt the strut assembly from the top and bottom, and replace with new components.
- Torque bolts to manufacturer's specifications (typically around 50-60 ft-lbs for strut bolts).
Replace Worn Bushings/Links:
- Inspect sway bar links and bushing for wear.
- Remove the sway bar link connections using a socket set and replace with new ones.
- Torque the new links to specifications (usually around 30-40 ft-lbs).
Check Ball Joints:
- If play is detected, remove the wheel and use a pry bar to assess the ball joint's condition.
- If worn, unbolt from the control arm and steering knuckle, and replace with a new ball joint.
- Ensure proper torque specifications (typically around 30-40 ft-lbs).

3. Reassemble and Lower Vehicle

Reinstall the wheel and lower the vehicle back to the ground.
Ensure all components are securely fastened and recheck torque on all replaced parts.
