Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, torque wrench, alignment equipment.
Park the vehicle on a level surface and engage the parking brake.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check all tire pressures.
Inflate tires to the recommended pressure found on the driver’s door jamb label.

3. Tire Inspection

Remove each wheel using a socket set.
Inspect tires for signs of damage or uneven wear; replace if necessary.
If any tires show excessive wear, consider rotating or replacing them.

4. Wheel Balancing

Mount the tires on a wheel balancing machine.
Adjust weights on the rim until the wheel is balanced properly.
Reinstall the wheels and tighten lug nuts to manufacturer torque specifications (usually around 80-100 lb-ft).

5. Wheel Alignment

Set up the vehicle on an alignment rack.
Adjust camber, toe, and caster angles to meet manufacturer specifications.
Confirm alignment settings are within acceptable ranges.

6. Suspension Inspection

Visually inspect suspension components for wear, such as bushings, ball joints, and struts.
Replace any worn or damaged components.
