Product review (1 stars): Don't do it!
DO NOT buy this bushing type idler pulley. It's not a matter of if it will fail, but when. I bought this idler assembly on July 11th of 2017 and it's already squealing like a pack of rabid rats like the oem one that came on my 2 year old dryer. No amount of lithium grease or turbine oil on the new part even helped the situation.

I'm replacing it with the newer sealed ball-bearing version (DC93-00634A) after finding out they updated the design due to the massive failure rate these bushing ones have had. Save yourself the headache and inevitable frustration and get the newer ball bearing style idler pulley assembly.
