Solution

1. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to check the pressure of all tires.
2. Inflate or deflate tires to the recommended pressure listed in the owner’s manual.

2. Tire Rotation

Sub-steps:
1. Lift the vehicle with a jack and secure it with jack stands.
2. Remove the lug nuts using a socket wrench and take off the affected tire.
3. Rotate the tires according to the recommended pattern (e.g., front to back, side to side).
4. Reinstall the lug nuts and torque them to the manufacturer’s specifications.

3. Wheel Alignment

Sub-steps:
1. Take the vehicle to an alignment shop with a proper alignment rack.
2. Have a technician perform a four-wheel alignment, adjusting camber, caster, and toe angles as necessary.
3. Verify alignment readings are within manufacturer specifications.

4. Suspension and Steering Inspection

Sub-steps:
1. Lift the vehicle and securely support it.
2. Inspect control arms, bushings, and struts for signs of wear or damage.
3. Replace any worn or damaged components with OEM or high-quality aftermarket parts.
4. Recheck alignment after suspension repairs.
