I found one of the internal tub blades loose yesterday about 5:30pm and promptly proceeded to tear into the dryer to try to get to outside of drum to tighten screw. I quickly found out that there is no access from back. Going to Google for help, I found several U-tube videos on repair of Maytag dryer and found out that access is from front. About 15 minutes later, I had front panel and top removed and could rotate the drum to tighten the loose holding screw. Total time less than 1 hour start to cleanup. Definitely better than a service call. Surprising the help out there now. Just got to remember to check out some of the procedures before running at the problem.
