Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, alignment machine, wrench set.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Adjust Tire Pressure

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

3. Inspect Tires for Wear

Remove the front tires using a jack and jack stands.
Examine tire tread depth and wear patterns; replace any tires showing significant uneven wear.

4. Suspension Inspection

Check suspension components for damage, including:
- Control arms
- Tie rods
- Ball joints
Replace any worn or damaged components with OEM or quality aftermarket parts.

5. Wheel Alignment

Utilize the alignment machine to measure the alignment angles (toe, camber, caster).
Adjust the alignment settings according to manufacturer specifications.
Tighten all adjustment bolts to the specified torque values.

6. Reassemble and Test

Reinstall the tires and lower the vehicle.
Test drive the vehicle to confirm that the pulling issue has been resolved.
