Could be a height sensor or failing suspension. Autozone have some repair manuals for popular vehicles on line for free, I think you need to sign up and give them your email address but it is free. There is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You get a one year subscription to year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual.
