Ok guys I thought I fixed the problem the other day but my Ty shreaded another serpintine belt. I yanked the belt and checked all the pully's they all spin freely and there are not any large burs or shape parts I could feel on any othe them. Now im stumped, I am running all the stock pullies except I have a polished march pully on my alternator, because the alternator was polished also. Any other ideas I included a few pics I know its kind of hard to tell by pics but maybe someone can pick up on something I am missing out on. It almost looks like the alternator is back to far to me but I dont know how that could be possible I think I got it back in there right.

That sounds like Mike is right actually.

I do have the stock pulley I will try that when I finish installing my shocks that was my next project try to figure out what is going on with the belt. I do have solid mounts on the truck also so I dont think the engins is shifting anywhere. Thanks for the help so far guys.

Re: Shreaded another belt
If you have a mechanics stethoscope listening to each of the pulleys with the truck running will help you narrow down which one it is. Sometimes when a bearing goes out, it won't be noticeable with no load on it. It will spin freely by hand. However when it's under a load, it will bind up. There is some serious tension on those pulleys with the belt installed...

I would do this. When I was having this problem about 12 years ago on a different truck it turn out that the tensioning pulley / set was fatigue and not keeping the correct amount of tension on the belt.
When you change your alternator pully, Did you keep the spacer that fits between the pulley and the fan ? It's not very big, so it is easy to over look, it like 1/8" to > 1/4" thick.

I have all March pullies on mine with NO issues what so ever.......does your tentioner pulley spin freely? Remove and inspect the entire tentioner and pulley to see if the bearings are done.
