The noise sounded like a bad bearing. I found the 2 rear rollers are bad. The right roller has actually come off the shaft. I replaced the 2 rear rollers with the new bearing style rollers.

"The customer said the dishwasher leaked two times, but when they ran it last night, it did not leak. I inspected the bottom spray arm and found food particles were stuck inside the holes. I cleaned out the little holes and jets on the bottom spray arm. I ran the dishwasher and after about a minute I open the door and noticed the bottom was full of suds. I dumped in vegetable oil and let it run to help cut the suds. I instructed the customer on soap usage and what type of soap to use. I let it run for about 10 or so minutes and it never leaked."

I verify that the front felt seal was ripping down the center and sticking out. I removed the drum and then removed the old seal and glued the new one on. I ran the dryer for five minutes and it sounds good.
