If adjusting arm height has no effect on the bass the arm is having a severe problem!
The bearings don't go out of adjustment, unless someone messes with them. They fail. Over-tightening the bearings is a simple way to damage them. They are supposed to be ever so slightly loose. They are not packed with grease- they don't need it.
