Solution

1. Tire Inspection and Replacement

1.1 Check all tires for proper pressure and adjust as necessary.
1.2 Inspect tires for uneven wear patterns; replace tires if they are excessively worn or damaged.
1.3 If tire replacement is necessary, mount and balance new tires using a tire changer and balancer.

2. Suspension Component Inspection and Repair

2.1 Raise the vehicle using a hydraulic lift or jack stands and remove the wheels for better access.
2.2 Inspect shocks and struts for fluid leakage or physical damage. Replace any defective components with OEM parts.
2.3 Check bushings and control arms for wear; replace any worn bushings or components.

3. Wheel Alignment

3.1 With the vehicle still on the lift, set up the alignment machine according to the manufacturer's specifications.
3.2 Adjust the alignment settings (camber, caster, toe) to the specifications provided in the service manual.
3.3 After adjustments, perform a test drive to ensure the alignment is correct and the ride is improved.
