Solution

1. Preparation

Gather tools and parts required for the repair.
Safely elevate the vehicle using a jack and secure it on jack stands.
Ensure the vehicle is on a flat surface and the engine is off.

2. Inspect and Replace Suspension Components

Inspect Struts and Shocks:
- Remove the wheel to access the suspension components.
- Check for leaks, dents, or physical damage on the struts/shocks.
Replace Worn Components:
- If any strut or shock is found defective, proceed to replace:
  - Remove the bolts securing the strut to the vehicle.
  - Disconnect any necessary components (brake lines, sway bar links).
  - Install the new strut/shock using the manufacturer’s torque specifications (typically 40-50 ft-lbs for strut bolts).
  - Reattach any components removed during the process.

Sway Bar Links:
- Inspect the sway bar links for wear or damage.
- Replace if necessary by removing the nuts at both ends and installing new links.
Control Arms:
- Check bushings on control arms for wear; replace if cracked or deteriorated.
Reinstall Wheel:
- Once all repairs are made, reinstall the wheel and torque to specification (typically 80-100 ft-lbs).
