Set out mouse traps. HAHAHAHA!!!!
More seriously, the squeaky driers I've fixed, I've had to remove a few screws (open the door, and look up to find them). Lift the top.
Remove a couple sheet metal screws (5/16 ratchet wrench) which hold the front panel on.
Remove front panel (swing away cause there are wires)
Remove drum, noting how small black belt loops around idler (lower left) and motor (also lower left).
Look for two idler rollers in back, way down low. About three inch diameter. Lube the roller shaft wtih something that doesn't attract dust, like silicone. Teflon. Graphite.
Reassemble. Which is a lot harder that it sounds "reassemble".
Pictures? Can't help you there.
