I have a beautiful 300TE wagon with the load-leveling system. I had a leak due to a bad hydraulic hose which I replaced. I had this problem before I replaced the hose....the rear end is extremely bouncy...constantly up and down with any bump or wave in the pavement. What is causing this?

Also: just recently the A/C won't come out of the center vents....it comes out of the defrost vents.....common? Suggestions?
