Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Use wheel chocks to prevent the vehicle from rolling.

2. Tire Pressure Adjustment

Tools Required: Tire pressure gauge, air compressor
Check each tire's pressure using the gauge.
Inflate or deflate tires as necessary to match the recommended pressure found on the driver’s side door jamb.

3. Alignment Adjustment

Tools Required: Alignment machine or alignment kit, torque wrench
Position the vehicle on an alignment rack.
Adjust the alignment angles according to the manufacturer’s specifications using the alignment machine.
Torque all adjustment bolts to the specified values.

4. Suspension Inspection and Repair

Tools Required: Jack, jack stands, socket set
Lift the vehicle using a jack and secure it with jack stands.
Inspect shocks/struts, control arms, and bushings for wear or damage.
Replace any damaged components with OEM or equivalent parts.

5. Tire Rotation or Replacement

Tools Required: Tire iron, jack, jack stands
Rotate tires if uneven wear is detected, or replace tires if they are worn beyond safe limits.
Ensure all tires are balanced after installation.
