Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use safety glasses and gloves for protection.

2. Tire Pressure Adjustment

Tools Required: Tire pressure gauge, air compressor.
Check the tire pressure using the gauge and adjust to the manufacturer's recommended PSI, typically found on the driver’s door jamb.

3. Tire Inspection and Replacement

Tools Required: Jack, jack stands, lug wrench.
Lift the vehicle using the jack and secure it with jack stands.
Remove each wheel and inspect tires for damage; replace any tires that are damaged or excessively worn.

4. Wheel Balancing

Tools Required: Wheel balancer.
Mount the wheel on the balancer and follow the machine's instructions to determine if weights need to be added or adjusted.
Apply balancing weights as necessary to achieve balance.

5. Wheel Alignment

Tools Required: Wheel alignment machine.
Position the vehicle on the alignment rack and follow the machine's instructions to perform a four-wheel alignment.
Adjust camber, caster, and toe settings as needed to meet manufacturer's specifications.

6. Suspension and Drivetrain Inspection

Tools Required: Wrench set, socket set, torque wrench.
Inspect all suspension components for signs of wear or damage; replace any worn parts.
Check driveshaft and axles for play or damage; replace if necessary.
