Solution

1. Preparation

Gather necessary tools and parts.
Raise the vehicle using a jack and secure it on jack stands.
Ensure the work area is clear of hazards.

2. Inspect and Replace Suspension Components

Inspect Struts/Shocks:
- Remove the wheel on the affected side using a socket set.
- Visually inspect the struts/shocks for leaks or damage.
- If damaged, proceed to remove and replace.
Remove Strut Assembly:
- Disconnect the sway bar link and any sensors attached to the strut.
- Unbolt the strut from the hub assembly.
- Remove the upper strut mount bolts in the engine compartment.
Install New Strut/Shock:
- Place the new strut into position and secure it with upper bolts.
- Reconnect the strut to the hub assembly and reattach the sway bar link.

3. Replace Worn Bushings or Links

Inspect Control Arm Bushings:
- If bushings show signs of wear, remove the control arm by unbolting it from the chassis and the hub.
- Replace with new bushings and reinstall the control arm.
Replace Sway Bar Links:
- If sway bar links are worn, remove them by unbolting from the sway bar and control arm.
- Install new sway bar links and secure with new hardware.

4. Reassembly and Final Checks

Reinstall the wheel and torque lug nuts to manufacturer specifications (typically 76-89 ft-lbs).
Lower the vehicle from jack stands.
Ensure all components are securely fastened.
