Solution

1. Preparation

Tools Required: Tire pressure gauge, alignment tool, jack and jack stands, socket set, torque wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheels to gain access to suspension components.

2. Inspect and Adjust Tire Pressure

Check the recommended tire pressure from the vehicle's door jamb or owner’s manual.
Inflate or deflate tires as necessary to meet specifications.

3. Perform Wheel Alignment

Using the alignment tool, check the camber, caster, and toe settings.
Adjust toe settings to within manufacturer specifications (typically around 0.05 inches for BMW).
Tighten all adjustment bolts to the specified torque value (consult the service manual for exact values).

4. Inspect Suspension Components

Visually inspect suspension components for any signs of wear, such as damage to control arms, bushings, and shocks.
Replace any worn components as necessary.
Ensure all bolts are torqued to manufacturer specifications.

5. Rotate Tires

Rotate tires to ensure even wear across all tires.
Follow the recommended tire rotation pattern (e.g., front to rear, side-to-side) as per the owner's manual.
Reinstall the wheels and torque lug nuts to the specified value.
