How is the bearing in it?

southerman

its good no wobble or play.

rebal

there is a nylon washer that wears out causing it to not run true then it starts ripping the belt by forcing it to ride the inner edges of the other pullies

Usually the belt starts driving you INSANE when the nylon (delrin?) bushing wears out and the belt hangs slightly over the side of the tensioner pulley. When the bushing wears out the tension arm gets crooked, that's why the pulley no longer lines up.

If the bearings feel ok and the belt doesn't squeal, I'd personally save the new part for when the old one wears out. It's stoopid easy to replace.
