Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Raise the Vehicle

Tools Required: Floor jack, jack stands.
Use a floor jack to lift the vehicle and secure it on jack stands for safety.
Remove the front or rear wheels, depending on the area of concern.

3. Inspect and Replace Worn Components

Inspect Struts/Shocks:
- Remove any protective covers to access strut tops.
- Look for leaks, dents, or physical damage on struts/shocks.
Replace Worn Components:
- If struts or shocks are damaged, replace them:
  1. Unbolt the strut from the lower control arm and upper mount.
  2. Install the new strut or shock and secure with bolts, ensuring they are torqued to the manufacturer’s specifications (typically 80-100 Nm, but refer to service manual).

4. Replace Sway Bar Links and Bushings

Tools Required: Wrench set, socket set.
Remove the sway bar link by unbolting it from the sway bar and control arm.
Replace with new sway bar links and bushings, ensuring they are properly torqued (usually around 40-50 Nm).

5. Reassemble and Lower Vehicle

Reattach the wheels and ensure all lug nuts are tightened to the manufacturer’s specifications (typically 110-130 Nm).
Remove jack stands and lower the vehicle back to the ground.
