How Do You Diagnose Car Suspension Problems?

To diagnose car suspension problems, look at the different symptoms of the car, such as the car pulling to one side or a steering wheel that feels like it is slipping. Each symptom leads to a different potential cause for suspension issues.

Look at the combination of symptoms and the different vehicle problems that often lead to those symptoms. For example, a car that is pulling more to one side might have improper alignment, uneven tire wear or low tire pressure. These are things that are easy to check even without extensive auto repair knowledge. A vehicle that has wheels that wiggle and wander might have excessive tire wear, wheels out of balance, uneven tire pressure or worn steering components. Many of these symptoms provide similar issues with a vehicle.

It is a good idea to check some of the vehicle components that tend to be common among multiple suspension issues, such as the tire tread and condition, alignment of the wheels, tire pressure and the balance of the wheels. Some other things to check include the leaf springs, shocks and struts, steering components and steering fluid. Steering fluid can lead to a vehicle that is difficult to steer. This symptom might also be due to a worn power steering belt, bad power steering pump or a power steering rack that is leaking.
