Solution

1. Tire Maintenance

Check Tire Pressure: Adjust the tire pressure to the recommended PSI found on the driver’s side door jamb.
Inspect and Replace Tires: Replace any tires that are worn beyond the tread wear indicators or have uneven wear.
- Tools required: Tire pressure gauge, tire changing tools.
- Safety warning: Ensure the vehicle is on a flat surface and supported by jack stands before working on tires.

2. Suspension Inspection and Repair

Replace Worn Shocks/Struts:
1. Lift the vehicle securely and remove the wheels.
2. Remove the bolts securing the shock absorbers/struts to the vehicle.
3. Install new shocks/struts, ensuring they are properly torqued to manufacturer specifications (typically around 15-25 ft-lbs).
4. Reinstall the wheels and lower the vehicle.
- Tools required: Socket set, torque wrench.
- Safety warning: Always wear safety goggles when working on suspension components.

3. Wheel Alignment

Perform Wheel Alignment:
1. Take the vehicle to a certified alignment shop.
2. Follow the technician’s recommendations for adjustments to camber, toe, and caster specifications.
- Tools required: Alignment machine (performed by a professional).
