I just grabbed the spare and lifted it up...getting one bolt in first and then the others. Easier than lifting one while sitting on my ass in driveway to rotate tires with my floor jack. 
I dont get any vibration or noise from the rear bumper at all..none...zilch...nada. After about 3 months of heavy use I had to readjust the locking clamp for a snugger fit when closed and latched but it is very very solid setup on my rig.
