My rear air ride rides low, what is the best remedy for this problem

I own a repair shop specializing in Cadillac in Pinellas Park. The air shocks are almost certainly leaking and worn out. But if there is a definitive "clunk" when hitting bumps the springs are weak as well. Check us out at cadillacrepair.biz or give us a call at 727-430-8750. We are very familiar with these cars and can definitely help you out.
