***I know f-bodies tend to lean a little toward the passanger side, but please read*****

About a month ago, a friend and I put on DMS springs and Bilstein shocks. All was fine until recently. Yesterday I noticed that the rear on the passenger side was much lower (maybe 2") then on the driver's side. I stood on the driver side door sill, and it made a creaking sound (similar to an old door opening). as the weight balanced out. Does anybody have any ideas about what the problem can be? I will try to get pics later on. Thanks.

 

Did you check the ride height both before and after you changed the springs? Always a good idea, so you can spot any problems. Or, did the 2" sag appear sometime after the spring install?

Are you sure you got the tops of the coils properly aligned in the slots in the upper spring seats?

 

The 2" sag appeared about a month after the install. Everything seemed well during the install...my friend that helped me is very good with cars and he did springs/shocks before on his car. Also everytime I get into the car it makes a loud creaking sound as some weight shifts toward the driver side. It has never done this before, and no I didn't gain any weight. It's raining now so it'll be a while before I can go take a better look at it.
