need complete instructions to replce rear drum support rollers

i have the front panel off and top panel loose. how do i remove drum? the right rear drum support roller is just flopping around on the shaft. should i replace the shaft also? if so, how do i remove shaft from panel? i don’t see any clip or nut on shaft to contain roller to shaft. any pictures, part numbers would help.
thanks, fred

With the top popped and the front panel removed all you gotta do is take the belt and Idler loose. Then grab the belt at the top of the drum and use upward force. Ease the drum out the front and set it to the side. The wheels wil be easily accessible then. Little triangles made of plastic retain or hold the wheels onto the shaft of these dryers. The wheel closest to the motor always wears out first.
