Solution

1. Preparation

Tools Required: Jack, jack stands, tire pressure gauge, alignment tool.
Safety Warnings: Ensure the vehicle is on a flat surface and engage the parking brake before beginning work.

2. Tire Pressure Adjustment

Sub-steps:
1. Use the tire pressure gauge to measure the pressure in all tires.
2. Inflate any under-inflated tires to the recommended PSI as specified in the owner's manual.

3. Tire Inspection and Rotation

Sub-steps:
1. Remove the wheels using a socket set.
2. Inspect the tread for uneven wear and look for any bulges or punctures.
3. Rotate the tires if uneven wear is detected to promote even wear.

4. Wheel Alignment

Sub-steps:
1. Set the vehicle on an alignment rack or ensure it is on a level surface.
2. Use alignment tools to measure the camber, caster, and toe settings.
3. Adjust the alignment according to manufacturer specifications, typically using a professional service if precise adjustments are necessary.

5. Suspension Component Inspection

Sub-steps:
1. Visually inspect all suspension components for signs of wear or damage.
2. Replace any worn or damaged components such as bushings, control arms, or struts.

6. Test Drive

Sub-steps:
1. After completing repairs, perform a test drive to ensure the vehicle no longer pulls to the left.
2. Observe if any new symptoms arise during the test drive.
