Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety.

2. Inspect Suspension Components

Raise the vehicle using a jack and secure it on jack stands.
Visually inspect the struts, shocks, and their mounting points for any signs of leaking fluid or physical damage.
Check sway bar links and bushings for cracks or separation.

3. Replace Worn Components

If any component is found to be damaged, replace it as follows:
- Sway Bar Links:
  - Remove the nuts using a socket wrench.
  - Replace the old link with a new one and torque to manufacturer specifications (usually around 30-40 lb-ft).
- Shocks/Struts:
  - Remove the strut assembly by detaching the top and bottom mounting bolts.
  - Replace with new struts, ensuring proper alignment and torque (typically 70-80 lb-ft for lower bolts).

4. Reassemble and Lower Vehicle

Reattach any components that were removed during the inspection.
Lower the vehicle from the jack stands and remove the jack.
Reconnect the battery.
