You crankshaft pulley could be loose try torquing it to specs and inspect the other pulleys double check belt tracking/alignment

In another forum I found many Montana's where the Harmonic Balancer has come apart which is causing the pully to be 1/2" out of alignement so I will check this now. Thanks everybody.

I had the same problem and the harmonic balancer (102K miles)had actually started to separate and caused the pulley to move forward. Oriellys to my surprise had it in stock so I suppose it is a common problem. At the same time I found everyone of the idlers/bearings(there are a few) were wore out so I replaced them
