Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, alignment machine, wrench set.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and the keys are removed from the ignition.

2. Tire Inspection and Adjustment

Tire Pressure:
- Use a tire pressure gauge to check the pressure of all tires.
- Inflate or deflate tires as needed to match the manufacturer’s specifications located in the owner’s manual or on the driver’s side door jamb.
Tire Condition:
- Inspect all tires for signs of damage or uneven wear.
- If any tires are excessively worn or damaged, replace them with new ones.

3. Alignment Adjustment

Set Up Alignment Equipment:
- Place the vehicle on an alignment rack.
- Attach alignment heads to each tire according to the equipment instructions.
Perform Alignment:
- Adjust the camber, caster, and toe settings as necessary to bring them within manufacturer specifications.
- Use a torque wrench to ensure all adjustments are tightened to specifications.

4. Suspension Component Check

Inspect and Tighten:
- Check all suspension components for wear or damage.
- Replace any worn parts, such as tie rods or control arms.
- Tighten any loose bolts to the manufacturer-recommended torque specifications.
