Drum vibrates unit and makes a rumbling noise

Hi, usually its the drum bearings that make a rumbling grating noise and need to be replaced.

Kia is bad with wheel bearings ;.About 80 to 100k they start going bad. You have to check them physically with a dial gauge or know how to inspect them in other manners. They cause a rumbling sound when they start to go bad.

You have to take the whole drum out and IT IS YOUR BEARING(s). Order all four of them

Hi Willie Bolden
Sounds like your problem is drum rollers are in need of lubrication or replacement.
Go to the following webpage for a schematic of your dryer and parts.

loud rumbling noise when running, unplug it, take the rear cover off and remove the drive belt. Then turn the inner drum by hand. If there is a grating noise, the bearings will almost certainly need replacing.
drain port take out and give a very good clean with warm water and makes sure all the holes are cleaned right through

the vibration and noise is most likely from the drum bearings wearing out to test the bearings try this out,,,
open the door, hold the top of the drum and lift it up, if it has any free lift in it the bearings are going, now spin the drum by hand and you should here the rumble off the bearings

That model of neptune dryer had a problem with the blower housings cracking. When the housing cracks, it binds forward into the blower wheel making a loud "rumble" noise and vibration. If you open the door and manually turn the drum and you hear a rubbing noise and feel alot of resistance, then you have a cracked blower housing and need to replace it. It is not an easy job to replace, so if your not familiar with dryers, you should have a technician replace it. Let me know if you have any further questions. shane

Normally the noise you hear is caused by the drum rollers having flat spots on them or needing lubricant.
If this is what is wrong It will make a kind of thumping noise.
When they need lubricant they will normally make a squealing noise also. You would lube the shaft and bearing area of the roller, using a good machine oil...something like "3 in One" oil.

If you remove the front cover and access the blower fan and see if it is still tight on the shaft. if it isn't it makes a rumble sound when started due to vibrating and after a while it makes more noise as it goes. Now I removed the fan and placed a shim in the flat area and matched the flat area of the shaft and replace it back on the shaft and it should solve it.
