Update: Took the top cover off plus the door w/front panels, cut out the belt (cracking) and removed the drum. I removed the tensioner and notice that its plastic wheel seems to be tight, doesn't spin very easily. Is this the noisemaker? Doesn't look repairable. The two rubber drum rollers spin fine with only a little play in their shafts. The motor has no discernable shaft play. I'll try replacing the tensioner and belt.
