Hi - I ordered the WE3M26KIT Front Load Repair Kit which I expect to arrive shortly to fix my DG05-US1 dryer. One piece included in the kit is the drum bearing. In order to replace this, there is a need to remove what appears to be a nylon retainer/bushing at the tip of the shaft. I have not been able to determine how to remove this - does the end of the shaft unscrew? If so, right hand thread or left? If not, how is the retainer removed for bearing replacement? Thanks.
