Open it up and check belt, idler wheel, rear rollers, front glides.
If a bearing has slop also check the shaft in case it also has to be replaced.

Check the blower wheel, is it tight on the shaft and and has nothing between it and the case.

Might as well also check the felt seals.
Just a thought!!! Before opening it up run your finger around the seals (from inside the tub) just to make sure that something is not jammed in there. Bra wires are famous for this.

Give everything a good check and a good cleaning. Might as well clean and check your vent system since you now have an overhauled dryer.

I have a maytag lde612 dryer. I think I need to replace the rollers and shafts. You indicate that the idler pulley should be replaced, but the exploded parts diagram lists nothing by that name. Any help. Thanks

Hey Tom, don,t forget to clean out the blower housing, and the check the vent to the outside, when you are done to be sure the vent is clear. A clogged vent will kill a dryer. Tom ApplianceEducator.com

Yes

While you have it opened up you might as well also check your belt, front glides, drum seals etc. Basically an overhaul.
Also give it a good cleaning including the blower wheel.
Good idea to check/clean your vent system while you are at it.
