I have an f30 330D, a couple weeks ago when doing an oil change I had the car on stands and couldn’t get one of the stands out. Due to this I jacked up the rear drivers side of the car to release the stand and heard a ping. I checked the spring and it’s perfectly fine and I changed the rear shock on the car just in case. The car is still sitting low on the rear right though, it’s not affecting performance or driving ability, what could it be?
