High Pitch Squeal - 87 Toy Truck

[jmb-Hunt]

My 1987 Pickup has started to make a high pitch squeal from under the hood. I have checked the belt tensions and all seem OK. I first thought power steering, so I removed the belt and started the truck. Squeal still there. It almost sounds like it's coming from the back of the Engine. It does not do this all the time. But under acceleration is most often or when you gas it sitting in neutral. But the weird thing is, it does it just sitting at idle.

i had two do that and both were broken alternator brackets belts felt tight but under pressure it tweaked bracket and they slipped bad just something to check though

Sometimes even though belts are tight they are worn out and will squeal. It is pretty cheap to throw a couple new belts on.

Check the tensioner bearings.

disconnect the speedometer cable and see if the nose goes away.
