Cause 1
Drive Belt
The drive belt is a very long, slender belt that wraps all the way around the dryer drum, around a tension pulley, and then around the drive motor. Over time, the drive belt can become frayed or otherwise damaged. If the drive belt is frayed or damaged, the dryer will be noisy as it turns. Inspect the drive belt for signs of wear. If the drive belt is worn, replace it.
Cause 2
Drum Roller
One or more of the drum rollers might be worn out. Many dryers have two drum support rollers on the rear of the drum, and some dryers have two more rollers supporting the front of the drum. When the drum rollers are worn out, they can cause the dryer to make a loud rumbling noise. To determine if the rollers are worn out, inspect the rollers. If one or more of the rollers are severely worn, we recommend replacing all of the rollers at the same time as a preventative measure. (The roller shaft can often be reused if it is in good condition. Clean the shaft thoroughly before installing the new rollers.)
Cause 3
Drum Roller Axle
One or more of the drum roller axles might be worn out. Most dryers have two drum support rollers on the rear of the drum, and some dryers have two more rollers supporting the front of the drum. Over time, the drum rollers and axles wear out, causing the dryer to make a loud rumbling noise. To determine if the drum roller axles are worn out, remove the belt from the dryer and try turning the drum by hand. If the drum does not rotate freely, check the support rollers for wear. If the rollers spin freely without wobbling, the axles do not need to be replaced. If a roller wobbles and/or does not spin freely, we recommend replacing all of the axles and rollers as a preventative measure.

Watched YouTube video on how to disassemble the dryer. Found lower rear support roller broken. Went to local sears parts store and bought set of two new rollers. New rollers much thicker and stronger than the original factory rollers. The plastic part of the roller is what was broken. No more noise.

Completely disassembled our Dryer this morning trying to figure out this knocking noise they are so meticulously designed and cheap but I finally traced the problem to one right front broken bracket on the frame that put the drum at an angle allowing the belt that goes around the drum to travel and was taking one of the floating bearing wheels that the drum floats on and banging it back-and-forth against the frame The motor is though is outstanding your next dryer goes out save the motor I don’t know what you can do with it but it is a great and well-built motor I have a whirlpool and I tell you knowing how interdependent every little piece of that thing is on keeping it straight I will never put one in without having it completely level and protected around the base the parts holding it together are so cheap they can bend just from leaning on it
