Hello Toyin, A car tilting to one side, particularly if it's noticeable from the rear, could be a sign of a few different issues. The rear springs could be a possible cause, but it's difficult to say for certain without more information or a proper inspection. Here are a few other possible causes that you may want to consider: Uneven tire pressure: Check the tire pressure on all four tires to make sure they are inflated to the recommended level. If one tire is underinflated, it can cause the car to lean to one side. Suspension system issues: A problem with the suspension system on one side of the car, such as a damaged shock absorber or strut, could cause the car to lean to one side. A worn or broken suspension component can also cause the car to sag on one side. Rear spring issues: As you mentioned, worn or broken rear springs can cause the car to tilt to one side. The springs may be worn out or broken due to age, mileage, or heavy loads. Alignment issues: Misaligned wheels can also cause the car to tilt to one side. This is more common if you've hit a curb or a pothole recently, or if you haven't had a wheel alignment in a while. If you're not comfortable inspecting the car yourself, I would recommend taking it to a qualified mechanic or suspension specialist for a proper diagnosis. They can inspect the vehicle and determine the exact cause of the issue, and recommend the necessary repairs to fix the problem.
