Engine Squeak?????????
ok heres the problem. i have a 1990 bronco with a 302 5.0, e4od trans, when i start the truck up, it runs quiet. after the idle goes dow, or when i put it into gear, there is this annoying squeaking sound. i changed the idler pulley, and i thought it was gone, a couple of hours later, it was back. i cant figure it out.any helpful hints?

Get under her when its squeaking, and check the exhaust....including the air tube to the cat. You can use a piece of wood or gloves to protect from the heat and keep touching around till the squeak stops....or starts.

The usual source of squeling in the Bronco is the serpentine belt, even though it may sound like a bad bearing. Usually, it depends on the humidity and it goes away in dry air, and returns in humid air. Try replacing the serpentine belt, or lubricate it with silicone oil. Another possibility is an accessory whose pulley doesn't line up properly.

If you want to make sure that it is your serpentine belt just take the belt off and start the truck for a few seconds and put it in gear to see if the noise is still there. If the noise is not there you pretty much know that it is the belt or one of the accessories.
