Hello. 1993 945T with 145K miles. The rear of the car is sagging on one side (driver's) such that it is about 1" lower on that side than on the other. I took a look and the spring does not appear to be broken on either side (but I'm not sure what it would look like if it were.) The driver's side bumper (the one that prevents too much travel of the suspension) is broken from what looks like too much compression. I suspect that I need new springs? I plan to replace the rubber parts on either end of the spring as well. For long trips, the car is really loaded and overload springs might be good. But other times it is loaded only with our family (2 adults, three children). I replaced the shocks about 50K ago with KYB ones. I was considering the monroe air adjust shocks (to control the ride height when loaded or not) with stock (Volvo) springs. But I could also do overload springs (IPD) with existing shock (or possibly something else). What would you suggest? Am I correct that the sagging problem is that I need new springs? The car isn't rusted and the metal parts that the springs seat onto look good.
Thanks
Steve
