If you've lowered the vehicle, it's normal for the chassis to appear sunken. If you haven't, or if you notice your vehicle leaning against a tire when it's parked, it's likely that you've broken one or more suspension springs. The noise that makes noise also indicates that you have something broken under the vehicle body. There are many factors that can damage the suspension.
In the event of an accident, different parts can be affected and any broken part can affect the smoothness of driving. Both front and rear collisions can cause suspension problems. If your vehicle has more potholes than usual, you may have a broken or defective strut that you need to replace. A trusted automotive professional can perform a test drive to precisely determine what the problem is.
While you may know if your suspension system isn't working properly, collision repair technicians are trained with the skills necessary to help restore and remodel vehicles after an accident. Parts, such as the ends of the tie rods, the suspension bushings, the shock absorbers and the struts, tend to wear out over time and need to be replaced to keep the vehicle running smoothly and comfortably. They are taught to align two- and four-wheel drive vehicles using the latest equipment, and receive hands-on training to replace suspension parts. The basic configuration of the front and rear suspensions includes axles, shock absorbers, upper and lower control arms, bearings, hub and steering hoses.
In the course on the underside of the vehicle and the SRS, students learn how to repair alignment and suspension assemblies.
