GE’s part number WE1M481 has been replaced by new part number WE1M507. This dryer drum slide is green, roughly 2-1/2 inches long, with a hole in one end. They are sold individually but most dryers that use this slide have two along with two white ones (part number for white slides is WE1M504). They go into the plastic bearing that is in the top, front of the dryer (part number for big, plastic bearing is WE3M26).
If I were replacing one slide, I would replace them all. Usually a new bearing (WE3M26) isn’t necessary. However, if the bearings are kept up, the bearing will wear out quickly.
