Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: Jack, jack stands, tire pressure gauge, alignment tool.

2. Tire Inspection and Adjustment

Sub-steps:
1. Remove the valve caps from each tire.
2. Use a tire pressure gauge to check the pressure and adjust to the recommended level specified in the owner’s manual (usually around 32-35 PSI).
3. Inspect the tread depth and condition of the tires, noting any irregular wear.
4. Rotate tires if needed to promote even wear.

3. Suspension Inspection

Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Visually inspect the control arms, ball joints, and tie rod ends for wear or damage.
3. Look for signs of leaking fluids from shocks or struts.
4. If any parts are damaged, replace them accordingly.

4. Wheel Alignment

Sub-steps:
1. Set up the alignment tool according to the manufacturer’s instructions.
2. Adjust the camber, caster, and toe settings to meet manufacturer specifications.
3. Tighten all adjustment bolts to the specified torque values.
4. Re-check alignment after adjustments to ensure they are within acceptable ranges.

5. Final Checks

Sub-steps:
1. Lower the vehicle from the jack stands and remove the jack.
2. Test drive the vehicle to check for pulling or drifting.
3. Re-inspect tire pressure again after driving to ensure it remains stable.
