Possible Causes:
* Broken or Damaged Spring(s): This is a very common cause. A broken spring coil will obviously cause a significant height difference. A sagging spring (losing its tension) will also cause one side to sit lower.
* Strut(s) or Shock Absorber(s): While struts and shocks don't directly control ride height, a severely worn or leaking strut can allow the car to sag on that side. This is less likely to cause a *significant* height difference compared to a broken spring, but it's possible.
* Control Arm Bushings: Worn control arm bushings allow excessive movement in the suspension, potentially leading to uneven ride height. This often manifests as a slightly uneven stance rather than a drastically different height.
* Spring Mounts: The mounts that hold the springs in place can become worn or broken. This will affect spring function and ride height.
* Uneven Tire Pressure: While unlikely to cause a *large* difference, significantly different tire pressures between sides can slightly alter the ride height. Check this first!
* Accident Damage: Previous accident damage might have bent a frame member or other suspension components, causing a persistent height difference.
How to Fix It:
1. Check Tire Pressure: This is the easiest and cheapest thing to check. Make sure all four tires are inflated to the correct pressure (check the sticker on the driver's side doorjamb).
2. Visual Inspection: Carefully inspect the suspension components on both sides of the car. Look for any obvious signs of damage, such as broken springs, leaking struts, or damaged bushings. Jack up the car safely and use jack stands (never work under a car supported only by a jack).
3. Professional Diagnosis: Unless you have significant mechanical experience, take your Mustang to a qualified mechanic or suspension specialist. They have the tools and expertise to accurately diagnose the problem. They can:
* Inspect the Suspension: A thorough inspection will pinpoint the faulty component(s).
* Measure Ride Height: They'll use specialized equipment to accurately measure the ride height on each corner of the car.
* Recommend Repairs: They will recommend the necessary repairs, which may include replacing springs, struts, bushings, or other components.
Important Considerations:
* Safety First: Working on your suspension requires proper tools, jack stands, and a safe working environment. If you're not comfortable working on cars, don't attempt to fix this yourself.
* Parts Quality: When replacing parts, use high-quality parts from reputable manufacturers. Cheap parts often don't last and can compromise your safety.
* Alignment: After any suspension repairs, you'll likely need a wheel alignment to ensure your tires wear evenly and your car handles properly.
Trying to adjust the suspension yourself without knowing the cause is likely to make things worse. A professional diagnosis is the best way to get your Mustang sitting level again safely and correctly.
