Lloyd B Arlington , TX May 02, 2017 Appliance: Maytag Electric Dryer MDE4000AYW Maytag Dryer Mde4000ayw: Squeeling dryer and black marks on clothes. How to replace Dryer Drum Support Roller. Replaced both rollers and shafts and the teflon bearing strips. One of the old rollers was in terrible condition (bearing shot), which also damaged the shaft. The other old roller was serviceable, but I changed it while everything was apart. The teflon strips were showing signs of wear, and were also changed. Dryer now performs as good as new.
