Product review (1 stars): Beware! Substandard knock-offs: failed after 9 months
I knew it was good practice to replace the rollers and the idler pulley when replacing the belt, so I did, in the latter part of September, 2011. The dryer started making "thunking" sounds last week (the week of 6/3/2012), similar to when the belt had a chunk out of it that prompted the first repair. The next day the sound interval was much more frequent than for a single bad spot in the belt.

So today (6/11/2012), when I opened it up, the rollers had seized on their spindles and the drum had been sliding on them, with a pile of rubber debris on the floor of the cabinet and a lot of rubber deposited in the groove of the drum. The pulley bushings were so tight on the spindles that the plastic roller wheels pulled off of their bushings, leaving the bushings behind. I had to use Vice-Grips and penetrating oil to get the bushings off. The hardened oil cleaned up okay but the spindles were discolored from overheating. Thankfully I had saved the old rollers and idler and left them in the bottom of the cabinet, so I oiled them (SAE 20 weight, non-detergent) and put them back in.

It appears that the bushings were plain steel, not sintered and oil-impregnated like they should have been. The replacement idler that I took back out looked like it had a plain brass bushing instead of the sintered bronze like it probably is in the original. The "by" line under the item name on the webpage is indicative: whirlpoll [sic]. I usually chuckle at other nationalities' mistakes in English words and phrases (or brands, in this case). This time, not so much.
