Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure that the tires are properly inflated to the recommended pressure.

2. Tire Rotation (if necessary)

Sub-steps:
1. Loosen the lug nuts on all four wheels.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the wheels and rotate them according to the recommended pattern for your vehicle.
4. Reinstall the wheels and hand-tighten the lug nuts.
5. Lower the vehicle and tighten the lug nuts to the specified torque.

3. Wheel Alignment

Sub-steps:
1. Set up the vehicle on an alignment rack or use a wheel alignment tool.
2. Check the camber, caster, and toe angles against manufacturer specifications.
3. Adjust the toe settings as necessary using the adjustment bolts on the tie rods.
4. Recheck all angles to ensure they are within the correct range.

4. Suspension Component Replacement (if damaged)

Sub-steps:
1. Identify and note any damaged suspension components during inspection.
2. Remove the damaged component using appropriate tools (e.g., socket set, wrenches).
3. Install the new component, ensuring all bolts are tightened to the specified torque values.
4. Reassemble any removed parts and check for proper fitment.

5. Final Inspection

Sub-steps:
1. Double-check tire pressures and ensure they are even.
2. Test drive the vehicle to ensure the pulling issue is resolved.
3. Make any final adjustments if necessary.
