Answer Hello Shane. You will need to check and see if there is any lint stuck inside the fins of the blower wheel. If so, this will cause the issue with the vibration of the unit.

Deborah for Model Number 110.68702894
Answer Hello Deborah, it sounds like you may be describing the belt tensioner 691366 or you can get the tensioner with this dryer repair kit 4392065 unless you already have these parts. Thanks!
Todd for Model Number mde5500ayw
Answer Hello Todd, This sounds like the idler pulley 6-3700340 since the other parts you have changed pretty much cover the other causes of the complaint. The belt 33002535 is what makes the noise, but it's because it's slipping over the part that is opposing rotation. As long as the belt looks good all of the way around, it shouldn't need replacement unless you just want a new one in while it's apart.
Mike for Model Number AP4373393
Answer Hello Mike. Check and make sure the pulley has the c clip holding it onto the shaft where it can't slide off. Also, that is has washers on both sides of the pulley. There should be a lip on the pulley on the side away from the motor to prevent the belt from coming off the pulley. If not, you will need to replace the pulley 6-3700340 on the unit. Hope this helps.
Carri for Model Number MDE9606AYW
Answer Hello Carrie. Based on the information you provided, it sounds like the motor W10410997 is bad and will need to be replaced on the unit. Hope this helps.
Claudia for Model Number MDE9357AYW
Answer hello Claudia. The pulley 6-3700340 should have a hole for the shaft to go into. Hope this helps.
