Kevin T Halls , TN March 07, 2015 Appliance: Maytag Electric Dryer DE312 Maytag Dryer De312: Normal wear and tear to my 25 year old maytag. How to replace Tumbler Bearing Kit. I replaced the seals and tub bushings to bring back a quieter operation and keep from doing more damage.I have done so since it was new in 1990. It still has a lot of kife left in it. And it beats buying a new unit any day. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
