From the rear, my 95 850 wagon looks like it is lower on the driver's side than the pass. Looks like the car is 'tilted' a tad. Tomorrow I will measure from the ground to the wheelwell on both sides in the rear. IF it is lower on one side than the other, is that a function of the SPRING? Hard to change?

 

I bet its your struts, my car did the same thing and still had the original struts and shocks

 

Could be struts or springs. Both support the weight of the car. Another less scientific way to check things is this: look at the car from behind where it's parked and see which way it appears to be leaning. Back the car out and reverse it in the space its in, and see which way it appears to be leaning then.

I only say this because I thought the same thing about my car. Turns out it was my driveway.
