Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and wear safety glasses.
Lift the vehicle using a jack and secure with jack stands.

2. Inspect and Replace Worn Components

Check Struts and Shocks:
- Remove the strut or shock mounting bolts using a socket set.
- Inspect for oil leaks or damage; replace if necessary.
- Install new struts or shocks by reversing the removal process, ensuring bolts are torqued to manufacturer's specifications (typically around 40-50 ft-lbs).
Sway Bar Links and Bushings:
- Remove the sway bar link bolts and detach from the sway bar.
- Inspect the bushings for cracks or wear; replace as needed.
- Install new sway bar links and bushings, torquing bolts to manufacturer specifications (usually around 20-30 ft-lbs).
Control Arms and Bushings:
- If control arms are damaged, remove the mounting bolts and detaching them from the frame.
- Replace with new control arms, ensuring bushings are properly seated.
- Torque control arm bolts as specified by the manufacturer (commonly around 60-70 ft-lbs).

3. Reassemble and Lower Vehicle

Reinstall any components that were removed for inspection.
Lower the vehicle carefully and remove jack stands.
Recheck all connections and fasteners to ensure they are secure.
