Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Adjust Tire Pressure

Use a tire pressure gauge to check all tires.
Inflate or deflate tires to the recommended PSI listed on the driver’s side door jamb.

3. Wheel Alignment

Tools Required: Alignment machine or camber/caster/toe gauge
Lift the vehicle using a jack and secure with jack stands.
Remove any wheel covers if necessary.
Follow the alignment machine instructions to adjust camber, caster, and toe to manufacturer specifications.
Tighten all bolts to the specified torque values (refer to the service manual for exact specifications).

4. Inspect and Replace Suspension Components (if needed)

Tools Required: Socket set, torque wrench, suspension puller
Remove the wheel for better access to suspension components.
Inspect control arms, bushings, and tie rods for wear.
Replace any worn components and torque to manufacturer specifications.
Reinstall the wheel and lower the vehicle.

5. Rotate Tires

Tools Required: Jack, jack stands, lug wrench
Lift the vehicle and secure with jack stands.
Remove the wheels and rotate them to different positions (e.g., front to back, left to right).
Ensure all lug nuts are tightened to the specified torque.
