Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Raise the vehicle using a jack and support it with jack stands.

2. Inspect and Replace Suspension Components

Inspect Shocks/Struts
- Remove the wheel to access the suspension components.
- Check for any signs of leakage or damage on the shock absorbers.
Replace if necessary: If the shocks/struts are worn or leaking, replace them with OEM or high-quality aftermarket parts.
Check Sway Bar Links
- Inspect the sway bar links for looseness or damage.
- If worn, remove the bolts using a socket set and replace the sway bar links.

3. Tighten Loose Components

Inspect Mounting Points
- Check all mounting points of the suspension for tightness.
- Use a torque wrench to tighten bolts to the manufacturer's specifications.

4. Clean and Lubricate

Sway Bar Bushings
- Remove sway bar bushings if worn.
- Clean the area and apply a suitable lubricant before reinstalling or replacing bushings.
