Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the vehicle is turned off and allow it to cool if recently driven.

2. Tire Pressure Check

Use a tire pressure gauge to check the pressure of all tires.
Inflate or deflate tires as necessary to match the manufacturer's recommendations (typically found on the driver's door jamb).

3. Wheel Alignment Adjustment

Tools Required: Alignment machine, torque wrench, socket set.
Loosen the nuts on the adjustable suspension components (camber bolts or tie rod ends).
Adjust the alignment according to the specifications provided in the service manual (typically front camber to -0.5 to 0.5 degrees, toe alignment to 0.05 inches).
Tighten the nuts to the manufacturer's torque specifications using a torque wrench.

4. Suspension Inspection and Repair

Tools Required: Jack, jack stands, socket set, pry bar.
Lift the vehicle and secure it with jack stands.
Visually inspect control arms, tie rods, and bushings for any signs of damage or excessive wear.
Replace any damaged suspension components with OEM parts.
Reassemble and lower the vehicle.
