Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Use a jack and jack stands to lift and secure the vehicle safely.

2. Inspect and Replace Worn Suspension Components

Inspect Struts and Shocks:
- Remove the wheel to access the struts.
- Check for oil leakage on the struts; replace if necessary.
Replace Worn Sway Bar Links:
- Use a socket set to remove the bolts securing the sway bar links.
- Install new sway bar links, ensuring they are torqued to the manufacturer’s specifications (usually around 15-20 ft-lbs).
Check Bushings:
- Inspect the sway bar bushings for cracks or wear.
- If damaged, remove the old bushings using a bushing tool and install new ones, ensuring a snug fit.

3. Inspect and Replace Wheel Bearings (if necessary)

Remove Wheel and Brake Assembly:
- Remove the wheel and caliper to access the hub assembly.
Check Wheel Bearing Play:
- Wiggle the hub assembly to check for excessive play.
- If play is detected, remove the hub and replace the wheel bearings with new ones, ensuring proper lubrication.

4. Reassemble and Test

Replace the wheel and torque the lug nuts to the manufacturer’s specifications (typically 76-83 ft-lbs).
Lower the vehicle and conduct a test drive to confirm repair effectiveness.
