Squealing serpentine belt
Hey everyone, My serpentine belt all of a sudden started making a very loud squeal that goes up and down with engine speeds. I can spray on belt dressing and it only stops for a couple seconds and comes back.
I took the belt off and it does have lots of small cracks in it. I will change that and see if it helps.
I took the belt off and turned all pulleys by hand and they feels smooth except the power steering, but that may be normal. Anyone know for sure if it would have a "bumpy" type feeling when you turn it by hand? Not bumpy like out of round, just not a smooth feeling when the pulley is turned.
My Bronco has also has a very dry sounding friction sound when it get very cold. Like a dry bearing when it gets below 20 degrees. Doesn't do it when it is warmer out.
I saw a few years back where someone posted the bearing numbers for the idler and tensioner pulleys. I wouldn't mind changing them out myself to save a few bucks. Anyone know the bearing numbers?
