I had the saggy a$$ on my 89
Its actually the rear coils that wear out over time. My 91 had the rear struts replaced about 6 months ago- but this one hasn't had issues with the coils yet. The mechanic that has looked after both of these cars told me that the coils in my 91 were replaced a few years ago- but the struts were terrible- and they leaked the air all the time. The car would be parked and the air compresor would kick in all the time. So it was disconnected- and I opted out of air rides for repalcements. I chose Monroe Sensatracs for the rears and I think that the front actually had the same. I disconnected the air ride all together, as these struts didn't need them. But they are half the diameter of the factory ones, and from what Im told lighter. They give the car a really nice ride. But both my 89 and the 91 had air ride.
