Durango Serpentine Belt pulley problems - 4/13/2008 3:20:12 PM    ejherrmann Posts: 11 Joined: 11/25/2007 Status: offline We have a few questions concerning the pulleys used with the serpentine belt on our '99 Durango. We have a loud squeak when driving and we're fairly sure it's the A/C pulley, we have already replaced the Idler pulley. My Questions are............. Is it possible to change just the bearing on the A/C pump pulley? Where can I find a breakdown of the pump to get a part number? Is the tensioner supposed to have spring tension on it at all times? I am able to use a wrench to remove tension to remove serpentine belt and it doesn't "spring back" it just stays put. Is that correct? It does apply pressure to the belt if I turn the tensioner CCW and it seems to hold. _____________________________ 2007 Ram 3500 Dually 6.7 2005 Ram 1500 Hemi 1999 Durango 1970 Satellite 1970 Charger 1967 GTX Post #: 1

I would also venture to say that the squeak is related to the same pulley. As for the A/C pulley issue, you might be able to replace the pulley itself, but I am not sure.

Most issues with a belt squeak are either the idler pulley, tensioner or the belt itself. I've thought of it to be the A/C before and it was not. .02 < Message edited by OneBadKota -- 4/13/2008 9:49:20 PM > _____________________________ LA360 Heart. http://www.cardomain.com/ride/2664603 (in reply to daddy_bear_21) Post #: 3
