Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Suspension Components

Inspection:
- Use a jack and jack stands to lift the vehicle safely.
- Inspect struts for leaks or damage, and check for any signs of physical defects.
- Examine the control arms and bushings for wear; replace if cracked or worn.
Replacement:
- If a strut is damaged, remove the wheel using a socket set.
- Unbolt the strut from the top mount and lower control arm using a torque wrench, following the manufacturer’s specifications (typically 30-50 ft-lbs).
- Replace with a new strut, ensuring it is properly seated and bolted in place.
- Reattach the wheel and torque to manufacturer specifications (usually around 80-100 ft-lbs).

3. Replace Sway Bar Links and Bushings (if necessary)

Unbolt the sway bar links from the sway bar and control arm using a wrench.
Replace the old links with new ones, ensuring they are tightened according to specifications.
Check and replace bushings if they are worn or cracked, using appropriate bushing tools for removal and installation.

4. Reassemble and Lower Vehicle

Double-check all connections and bolts for tightness.
Reconnect the wheel and lower the vehicle from the jack stands.
Reconnect the negative battery terminal.
