Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative terminal of the battery for safety.

2. Raise the Vehicle

Use a jack to lift the front end of the vehicle securely.
Place jack stands under the vehicle to ensure it is stable during repairs.

3. Inspect and Replace Suspension Components

Inspect the Control Arms:
- Check for any cracks or worn bushings.
- If damaged, remove the control arms using a socket set and replace them with new parts.
Examine Struts/Shocks:
- Look for signs of leakage or damage.
- If replacement is needed, detach the strut assembly and replace with a new strut, tightening bolts to manufacturer specifications.

4. Inspect Wheel Assembly

Check Wheel Bearings:
- Spin the wheel to listen for grinding noises.
- If they are faulty, remove the wheel and replace the bearings.
Inspect Tires:
- Replace any tires showing significant wear or damage.
- Ensure the tires are properly balanced after installation.

5. Reassemble and Lower the Vehicle

Reinstall any removed components, ensuring all fasteners are properly torqued.
Remove jack stands and lower the vehicle to the ground.
