I know this is a total NOOB question. However, my cars rear end is sagging. I do plan on doing the suspension sometime soon, but since my car is still under warranty, I would like to get it fixed and sell the OEM equipment in time. My question is it the shocks or the springs? I just had them do the front struts a week ago and I just noticed it yesterday sagging pretty bad. I know that the front wheel gap is huge like 3.5 - 4 inches, but the rear is only about 2 - 2.5 inches. It looks so LAZY!

 

I believe a sagging rear end is most likley due to springs... Someone correct me if I'm wrong. If your car's under warranty, might as well have them change out the rear springs and struts...
