I have just replace the Idler pulley situated directly below the alternator, not the tensioner Idler pulley. This was on my to do list after renewing the Tensioner Pulley, Air con compressor idler pulley bearing and the bearing on the steel idler pulley under the power steering pump.
This last pulley was in the worst condition of all, both the bearing and the actual pulley. The pulley wheel is plastic and the surface had worn down to a point I consider myself very lucky it had not cracked or ****tered. A replacement from the UK , LRseries.com, was 18 pounds shipped. It comes as a kit with bolt, bushes and O-ring. The new one is a solid steel lump so an improvement which should last indefinitely.
I have read there was a recall in the USA for the idler pulley but cant find anything on other markets. I would suggest a good look at the pulley is in order, it should be flat across the surface. If you have ridges at the edges the plastic is wearing away
I have tried to get a measurement of the thickness left on the old pulley main surface, it not exact but I recon no more than .5mm. Its 1.5mm on the outer edges so I presume thats the thickness when new
