Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Tools Required: Floor jack, jack stands, lug wrench, torque wrench, alignment tool, tire pressure gauge.

2. Tire Pressure Adjustment

Use a tire pressure gauge to measure the pressure of each tire.
Inflate or deflate tires to match the recommended pressure specified in the owner's manual or on the door jamb sticker.

3. Alignment Adjustment

Using an alignment tool, check the alignment angles of the front and rear wheels.
If misalignment is detected, adjust the camber, toe, and caster angles according to manufacturer specifications.
- For example, front toe should be approximately 0.0° ± 0.1° depending on the model.

4. Suspension Inspection and Repair

Raise the vehicle using a floor jack and secure it with jack stands.
Visually inspect suspension components for any signs of wear or damage.
Replace any worn components (e.g., shocks or control arms) with OEM or high-quality aftermarket parts.
Tools Required: Socket set, wrench set, replacement parts as needed.

5. Final Checks

Recheck tire pressure after adjustments.
Rotate tires if necessary, following the manufacturer's recommended rotation pattern.
Lower the vehicle and torque lug nuts to the specified value (typically 80-100 ft-lbs).
