Product review (5 stars): These are a great direct fit for the part
These are a great direct fit for the part.  I will say, they seem a little "looser" than the originals but that could be a result of years of lint buildup.

That said, the fix takes about 2 hours, to replace all 4 wheels (which you may as well since you just ripped your dryer open) I'd recommend an extra set of hands but there is a YouTube video that shows how to do this.

One caution, the inside of the dryer is sharp! I have a nice small new scar as a result of this fix.

Bottom line, this is probably the reason your dryer is making noise and, once you install these and clean out the inside cabin of the dryer, it'll run like new!
