When I start my car, the rear end by the tires sounds like a motor is running. The rear end of my caddy rides really low. What is that sound and how do I get my car to riding level?

Looks like two different suspension systems were available on your deville ( soft ride and sport suspension ) but if you hear a sound you probably have the air suspension and AC Delco has replacement shocks available for around $300, probably need a tech to diagnose this so you don't waste money changing parts that are still good

what u are hearing is the air pump running if it runs all the time theres a leak in the system somewhere the pump is located on top of the rear axle you have to jack the car up or get it on a lift to get at it

About 4 yrs ago, I asked the dealer why my Caddy was riding low. Do I need shocks? They told me 'no'. Two yrs later, a friend of the family (former Cadillac Srv Mgr) found my compressor was shot. After it was replaced, my bootlegging Caddy still rode low. Then the switch in the trunk was replaced...lowrider still not fixed. Last year, at a military Auto Hobby Shop, I was getting new tires put on and the guy says to me "You need new shocks!" Put new shocks on and finally, my Caddy was riding like a charm.
