Air Ride in 97 Deville

Hi I just bought this 97 a few weeks ago and the thing seems to scrape alot in the rear going in and out of driveways and such. Is there a speck for it or a way to check it? It drives nice down the road. Its just the driveway scraping .

could be the vacuum pump going.
try firing up the car, and letting it idle for a minute prior to heading out the drive.
if it scrapes less, or not at all, it could be a weak pump, or a more common ocurrence is a vacuum leak in some of the hard plastic lines under the car.
if you want to keep the ride control, it's dealer parts.
Monroe makes a swap-out kit.

hope this helps,
chris
