I've noticed a few times that after I park my car, it seems like the front suspension is significantly higher than the rear. This summer I replaced the front suspension and although the ride feels fine, I am worried about possible screw-ups that could cost me in the future. Anyone have a similar story with a possible solution?

maybe you have a leak in the rear bag(s)? the only possible way i think your front end IS higher than the rear, is probably your ride height sensor. but i doubt that though! what did you replace, just the front struts?
