Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is on a level surface and securely lift the vehicle using a hydraulic jack and jack stands.

2. Tire Pressure Adjustment

Sub-steps:
1. Remove valve caps from each tire.
2. Inflate or deflate the tires to the recommended PSI found in the owner’s manual or on the door jamb.
3. Replace the valve caps securely.

3. Wheel Alignment

Sub-steps:
1. Mount the vehicle on an alignment rack.
2. Adjust the front and rear alignment settings to manufacturer specifications using the alignment machine.
  - Front camber: -0.5° to +0.5°
  - Front toe: 0.05° to 0.15° in
  - Rear camber: -0.5° to +0.5°
  - Rear toe: 0.1° to 0.2° in
3. Tighten all adjustment bolts to specified torque values (typically 50-60 lb-ft).

4. Suspension Inspection and Repair

Sub-steps:
1. Visually inspect all suspension components for cracks or excessive wear.
2. Replace any worn parts (bushings, control arms, shocks) with OEM or high-quality aftermarket parts.
3. Recheck alignment after replacing suspension components.
