Solution

1. Preparation

Gather tools: Tire pressure gauge, alignment machine, socket set, and torque wrench.
Ensure the vehicle is on a level surface and park securely.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check each tire's pressure.
Inflate or deflate tires as necessary to match the manufacturer's recommended specifications found on the driver’s door jamb.

3. Wheel Alignment

Align the Vehicle:
- Lift the front of the vehicle using a hydraulic jack and secure it with jack stands.
- Remove the front wheels if necessary for better access.
- Attach the alignment machine according to the manufacturer's instructions.
- Adjust the camber, caster, and toe settings to meet factory specifications as indicated in the vehicle’s service manual.
Torque Specifications:
- Ensure all suspension bolts are torqued to the manufacturer's specifications after adjustments.

4. Inspect and Replace Components

Inspect suspension components for wear:
- Look for play in ball joints, control arms, and tie rods.
- Replace any worn or damaged components as necessary, using appropriate tools and torque specifications.

5. Test Drive and Final Adjustments

Reinstall wheels if removed and lower the vehicle.
Test drive the vehicle to check if the pulling issue is resolved.
Make any final adjustments to alignment if necessary based on test drive feedback.
