Solution

1. Preparation

Gather tools, including a socket set, torque wrench, alignment tool, and jack stands.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Adjustment

Inflate Tires: Check and adjust tire pressure in all tires to the recommended levels as indicated on the door jamb.
Tire Rotation: If uneven wear is present, rotate the tires to promote even wear.

3. Suspension Component Inspection

Visual Inspection: Examine all suspension components for cracks, rust, or damage. Pay particular attention to control arms and bushings.
Test for Play: Use a pry bar to check for excessive play in the bushings and ball joints. Replace any worn parts.

4. Steering Alignment

Alignment Setup: Using the alignment tool, measure the camber, caster, and toe angles.
Adjustments: Adjust the tie rods to correct toe alignment. Follow the specific torque values from the manufacturer’s specifications for securing tie rod ends.
Test Drive: After adjustments, perform a test drive to ensure the vehicle tracks straight.

5. Final Checks

Recheck Tire Pressure: After all adjustments, recheck the tire pressure.
Inspect for Vibration: Drive at various speeds to ensure there is no vibration in the steering wheel.
