LG Dryer Loud - Not Drum - DLE5977W

Hey Guys!  First off thanks for any help you may have to offer.  Just got a couple questions for you. 

My LG dryer recently developed a pretty loud noise.  I start it up and as soon as I hit "go" there is a loud rumble noise, then it quiets down as it spins but is still rumbling as it goes. First thought was cracked drum but did not see a crack anywhere.  So next thought was rollers, so I ordered four new rollers and am waiting on those to arrive.  But I've been thinking since there is a loud noise at start up do you think its the pulley system and belt?  Should I go ahead and order one or just wait until I try the rollers?

Thanks guys!

Replace the rollers and that should resolve your noise issue.

you may want to look in the blower wheel, make sure you don't have a wad of lint or dryer sheets in it. That would make a rapid vibration.

New rollers come in today so I totally disassembled the dryer this morning.  Problem is the rollers look fine, and roll fine on a hard surface.  Belt looks great also, and again no cracks in the drum.  I guess I'm going to try the new rollers anyways and see if that takes care of the problem.  Removed lint from the blower wheel also.  Even though the belt looks fine, would it need to be replaced?  I just don't know what else it could be, if the rollers don't work.

Check the drum, front & rear, where the rollers ride. Make sure there are no cracks there. I've seen it happen.

Yeah I've looked that drum over about 100 times and can't find anything.  New rollers come in today around 1 so I'll throw them on anyways, and see what the deal is.  After that I guess I'll try the belt if it doesn't fix it, but who knows.

Oh and thanks for the help!

make sure you clean the posts where the drum rollers mount with some 00steel wool to clean up anything stuck to the post. If you don't the rollers can not spin free. Test each roller when you have it open if you give them a spin and they only spin 3-5 times around you have a bunch of build up on the post and in side the glide of the wheel. After you clean them up and get the rollers spinning free your noise should go away. The drum could be turning on the rollers but the rollers are not spinning easy causing the howl you hear.

Okay think I have it figured out.  The rollers seemed great and they were actually the blue ones.  I think it is the blower wheel.  When you put that Squared off plate onto the bolt, the squared lock plate should no longer be able to spin inside the wheel right.  The blower wheel just keeps spinning all around that thing. I think that's the problem.

Yep that was the culprit.  Went ahead and threw the drum on without a blower wheel and cycled by hand and it went just fine.  Great now I get to wait for the part.
