if i raise my car completely in the air and then lower it down......the rear stays ok but the front wheels end will stay low to the floor and the instrument panel will say too low to drive.....then after few minutes while the car is on the front goes up and stays up.........also it seems the front is not all that tight or rather unstable when i drive......i also own a 99 s320 and that front is very tight......???????????? any suggestions
