Solution

1. Preparation

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

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle at the designated jacking points.
Secure the vehicle with jack stands to ensure safety.

3. Inspect and Replace Suspension Components

A. Check Shock Absorbers/Struts

Remove the wheel to access the suspension.
Visually inspect the struts for leaks or signs of wear.
If damaged, remove the strut assembly by unbolting the top mount and bottom bolts.
Replace with new OEM or high-quality aftermarket struts and torque to manufacturer specifications.

B. Examine Sway Bar Links and Bushings

Check the sway bar links for play. If worn, unbolt and replace with new links.
Inspect the bushings for cracks or deterioration. Replace if necessary.

4. Tighten or Replace Loose Hardware

Inspect all bolts and nuts in the suspension assembly for tightness.
Torque any loose bolts to manufacturer specifications. If any are stripped or damaged, replace them.

5. Reassemble and Lower the Vehicle

Reinstall the wheel and tighten lug nuts in a crisscross pattern to ensure even torque.
Carefully lower the vehicle back to the ground and remove jack stands.
