Loud bumping sound from dryer. - Amana ALE443RAW Gas Dryer

i don't know. dryers i have repaired with this bumping symptom have been warn plastic wheels the dryers
sit on while turning. a damaged wheel caused noise.

Sounds like you have found the problem. The bearings get hot and melt the housing. Replace the nozzle may be the solution.

-Every thing are worn out. The tumble is not round any more, seal is loose so any loose thing or seal hit a bump. It will make sound.
This is normal for old dryer.

The drum on some dryers are driven by a rubber covered wheel beneath the rear of the drum. When the dryer is at rest, the drum sits still on that wheel. The longer the dryer sits still, the more the drum pushes down on that wheel and eventually causes a slight indentation in that wheel. When the dryer runs and then stops it sits at a different spot on the wheel. After a number of years of use, this wheel gets a number of these indentations and as the wheel ages the rubber loses its ability to return to its' original shape and causes a "bump" as the drum contacts these indentations. Enough of these "bumps" in a row sets up a vibration causing a rumbling sound that gets worse and worse. The vibration in my Whirlpool got bad enough to move the dryer around the floor.

There is a kit available to repair this problem for around $35 that consists mainly of a new wheel and belt and it is fairly simple to do.

Many dryers use rollers or wheels to support the clothes drum. When these rollers are worn, they can be noisy. You should replace the whole set of rollers at the same time.

chances are that noise is the ball joints telling you they are dry and have no grease and they should be replaces fairly soon

The noise could be your drum rollers need lubricant or replacement.
When the drum rollers get flat spots on them they will make a bumping/thumping type of noise.
The grinding noise sounds to me like the drum rollers are in need of lubrication.

Sounds like you need new drum rollers installed, when they get old they squeak,squeal, and make loud bumping noises.
