Solution

1. Preparation

Tools Required: Tire pressure gauge, jack, jack stands, wheel alignment tool, torque wrench, and suspension inspection tools.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery if working on electrical components of the suspension.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the air pressure in all tires.
Inflate or deflate tires to match the specifications listed on the driver’s side door jamb.

3. Tire Rotation

Loosen the lug nuts on the front and rear tires using a socket set.
Use a jack to lift the vehicle and secure it on jack stands.
Rotate the tires according to the recommended pattern (e.g., front to back, side to side) for your vehicle.
Reinstall the lug nuts and torque them to the manufacturer’s specifications (typically 100-120 ft-lbs for Mustangs).

4. Alignment Adjustment

If misalignment is detected, take the vehicle to a professional alignment shop.
Ensure the alignment settings are adjusted to the manufacturer specifications (often available in the service manual).
Confirm that the adjustments are made to both the front and rear wheels as required.

5. Suspension Inspection and Repair

Inspect all suspension components for wear; replace any damaged parts as necessary.
Ensure that struts and shocks are functioning properly; replace if leaking or worn.
Re-torque all suspension components to the specified torque settings.
