I am experiencing the rear thumping noise also. It is a bushing more then likely. might be a subframe bushing.
tell if you find out.
also, check your hoses again, they may look fine, but twist them a little to check if they only look fine. I know my vacuum hoses looked fine, but under closer inspection they were holy. (not the religious type.)
We all get the urge...Saturday early morning...nothing to do till noon...
