Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the tires are cool before inspection.

2. Check and Adjust Tire Pressure

Tools Required: Tire pressure gauge, air compressor
Use a tire pressure gauge to measure the pressure in each tire.
Inflate or deflate tires to match the manufacturer’s recommended pressure (found in the owner’s manual or on the driver's side door jamb).

3. Perform Wheel Alignment

Tools Required: Wheel alignment machine
Position the vehicle on the alignment rack.
Follow the machine's instructions to adjust the toe, camber, and caster settings to factory specifications.
Typically, the front and rear toe should be set to within ±0.1 degrees of factory specs.

4. Inspect and Repair Suspension Components

Tools Required: Socket set, jack stands, torque wrench
Lift the front and rear of the vehicle using a jack and secure with jack stands.
Inspect control arms, bushings, and struts for wear or damage.
Replace any worn components, ensuring to torque bolts to manufacturer specifications.

5. Rotate Tires

Tools Required: Jack, jack stands, lug wrench
Remove the wheels and rotate them following the recommended rotation pattern (typically front to back and side to side).
Reinstall wheels and torque lug nuts to the manufacturer’s specifications (usually 80-100 ft-lbs).
