Hi not long bought my range rover and rear left sat down when parked making the car look lop sided and sometimes overnight the car would drop really low and take ages to come back up on starting the engine. I had both rear air springs replaced at the weekend and the car comes up really fast and does not drop overnight yippeee. However when I park up at work ,I park on a slight incline with a slight camber on the parking space and again the left back side drops or looks like its at an angle but when I look at the wheel arch the front seems the same level as the rear and when I park on the flat the rear end sits square . Any ideas if this is normal ??
