New idler pulley movement / wobble, is this normal? (video)
I just installed this yesterday, and the serpentine pulley has a bit too much movement for my taste. Does anyone see this type of movement in their serpentine pulley?

yup, those things are garbage. i bought mine from EC and after a few weeks it started making noise. i thought it was a bad bearing but upon further inspection its the clearance between the bearing and the pulley is off allowing the bearing to wiggle within the pulley.
i went back to stock. higher quality by far, even though its plastic. not sure how all the aftermarket companies get these awesome reputations LOL
edit: i forgot to say, the rattle i was getting was from the sc pulley and poly v pulley making contact with each other. it was exactly like your video but much more exaggerated as i ran mine longer. i just left her idleing one day and heard it from about 15' away. get a refund as its only going to get worse.
straight garbage product. seems consistent for the MB aftermarket http://sendvid.com/278p35kj

Does anyone else have issues with the UPD or EC idler / tension pulleys? I drove the car about 60 miles today and the movement seemed to get worse. The seller (ebay) is offering a new set, but I may just want a full refund if these are known to give people trouble.
