Solution

1. Preparation

Tools Required: Tire pressure gauge, alignment machine, jack stands, socket set, torque wrench.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure of each tire.
Inflate or deflate tires to the manufacturer's recommended pressure, usually found on a sticker inside the driver's door frame.

3. Tire Rotation and Inspection

Remove the tires using a socket set.
Inspect each tire for uneven wear patterns; replace any tires that are excessively worn.
Rotate the tires if necessary to promote even wear.

4. Wheel Alignment

Set up the vehicle on an alignment machine according to the manufacturer's specifications.
Adjust the camber, caster, and toe settings to align the vehicle properly.
Tighten all adjustment bolts to the specified torque values provided in the service manual.

5. Suspension Component Inspection

Inspect control arms, bushings, shocks, and struts for wear or damage.
Replace any worn or damaged suspension components as necessary.

6. Final Checks

Reinstall the wheels and torque the lug nuts to the manufacturer's specifications.
Test drive the vehicle to confirm that the pull has been corrected.
