Product review (5 stars): Worked great for our LG TROMM gas dryer
I ordered this idler pulley as part of a repair to replace the drum rollers on our LG TROMM dryer at the same time - I also replaced the belt, which had started to show cracks and wear.

I would also recommend to take a moment and vacuum out the accumulated lint and small items that wind up inside the dryer housing while the dryer drum is out to replace this idler pulley.
