Hi, i have a 1995 Cadillac Fleetwood Brougham with 39,000 miles and i am having an issue with the right rear sagging on occasion. I have been doing a little reading on line and i see that there is a position sensor on each corner of the vehicle and i was thinking that might be the problem. If there is anyone with knowledge of this system i would be grateful for any input you might have. Thanks O.Russotto
