Serpentine belt

Greetings all.

idler pully bearings could be going. You need to remove the belt and check Idler ,tensioner and other relevant pulleys for bearing play or bad bushings.

A lot of times its the tensioner. When it goes bad, it will tilt just a tad, allowing the belt to shred at the edge after interfering with something (other pulleys, etc). Cheers!

Count the amount of grooves on your pulleys and then on your belt. Some years of trucks had 7 groove and some had 8 groove pulleys.

I had the very same problem, turned out to be the water pump going bad. The water pump pulley was tilted letting the belt fray on one side. Replaced pump and no problems since.

I had a bad idler pulley. Another time the vacuum pump mount was extremely loose.
