maytag drum rollers

[cuzzin sam]

  Hi folks, I have a general question about Maytag drum rollers. I've read about the blower wheels also causing the rumble but...on the dryer I'm looking at the blower wheel is tight on the shaft, no binding or wobble, and the rollers don't seem to have any wobble on thier shafts. I can see some up and down movement of the drum itself as its running (maybe 1/4 inch or so) and on the tentioner pulley bracket there's a little side to side play with the belt off but the pulley wheel itself doesn't have play on it's shaft It looks like the bracket could be bumping into the motor but doesn't seem to be moving as the machine runs. My long winded question is this  - is the small amount of rise and fall of the drum an indication of flat spots on the rollers causing the rumble or is it more likely that the lateral play in the tentioner bracket is the cause.

 As usuall, many thanks, Cuzzin Sam
