I've come to the conclusion that my car leans to the left a little. At least from the rear it looks that way. After months of thinking that my eyes were fooling me I finally meditated for a few minutes before noticing it really seems to lean. When no one is in the car it seems I have one 300 + lbs passanger sitting on the rear left.

An interesting note is that when I make a somewhat of a hard right turn I hear a banging noise that seems to come from the rear left shock. The same area that seems to sag. Help!
