Thanks, Markus! It's all put back together now (and driving SMOOTH, I might add!), but I recall the tensioner seemed to have good and strong spring pressure/resistance when I was re-installing the belt. (I had to switch from a combination wrench to a longer-handled breaker bar to hold against the strong spring resistance while installing the belt.) As mentioned above, I also replaced the tensioner and idler pulley bearings, so I have no concerns there. I do have a feeling I'll be back in this area to deal with the apparently rattling power steering pump at some point here, and maybe I'll do some more visual observations of the belt vibrations at different engine rpms at that time.
