Solution

1. Tire Inspection

Sub-steps:
1. Visually inspect each tire for cuts, bulges, or foreign objects.
2. Measure tread depth using a tread depth gauge to ensure it meets safety standards.
3. Rotate tires if uneven wear is present.

2. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to measure the pressure in all four tires.
2. Inflate or deflate tires to match the recommended PSI found in the owner’s manual or door jamb.

3. Wheel Balancing

Sub-steps:
1. Remove the wheel and tire assembly from the vehicle.
2. Mount the wheel on a balancing machine.
3. Adjust weights as needed until the wheel is balanced.
4. Reinstall the wheel and torque lug nuts to manufacturer specifications (typically 100-150 ft-lbs).

4. Suspension Inspection and Repair

Sub-steps:
1. Inspect all suspension components (control arms, bushings, struts) for wear and damage.
2. Replace any worn components with OEM or equivalent parts.
3. Ensure all bolts and fasteners are torqued to manufacturer specifications.

5. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Adjust camber, caster, and toe angles as needed according to manufacturer specifications.
3. Test drive the vehicle to ensure proper alignment is achieved.
