Bad belt tensioner pulley

If you need parts for your Jeep Wrangler JK or JL O'Reilly auto parts is not the place for it. I am now going on my 3rd belt tensioner.
So the first 1 they warranty Because it comes with the 3 year warranty. Then the warranty part Failed, i took that one back, They said the warranty part doesn't come with a warranty so you're basically screwed and you have to get a different one... Now that's a joke. So with that said stay away from O'reilly auto parts especially the one in Elsmere KY
