Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to prevent the vehicle from rolling.

2. Inspect and Adjust Tire Pressure

Tools Required: Tire pressure gauge
Check each tire's pressure and inflate or deflate as needed to match the manufacturer's recommended PSI found on the driver’s door jamb.

3. Perform Wheel Alignment

Tools Required: Alignment machine
Position the vehicle on the alignment rack.
Follow the machine's instructions to adjust the camber, toe, and caster angles to factory specifications.
Confirm the alignment readings are within acceptable limits.

4. Inspect and Replace Suspension Components (if necessary)

Tools Required: Socket set, torque wrench, pry bar
Visually inspect all suspension components for wear.
If any components are damaged, replace them with OEM or high-quality aftermarket parts.
Reassemble and torque components to the manufacturer's specifications.

5. Tire Rotation

Tools Required: Jack, jack stands, tire iron
Lift the vehicle and secure it with jack stands.
Rotate the tires according to the vehicle’s recommended rotation pattern.
Lower the vehicle and check tire pressure again.
