Hi,

I'm new here and enjoy the site. I have a question for anyone who might see this and be able to offer an opinion:

I have a 1992 Bronco XLT 4x4. I have been experiencing a high pitched squealing noise under the hood. This only happens when I am not accelerating.

I looked under the hood and the noise is coming from an area below the surface. It is an area in the center and a bit deeper than I can see.

Thanks again,

Griff

Thanks for the reply. I apologize for the knuckleheaded 'surface' description.

I've just obtained this Bronco recently from my brother. He kept it in excellent shape and as stock as possible. I'm trying to uphold the tradition.

Hi,

The noise doesn't change. I just took it around the block. I checked the serp. belt and it was taught. I did see a little movement in one of the lower pulleys. Not a lot.

The main characteristic though is the noise stops when I hit the gas, starts right back up when I take my foot off it.

I appriciate the replies...I thought I might get one by tomorrow!

You might try hitting each pulley with a lubricant one at a time. I experienced a similar noise once and it turned out to be the power stearing pulley. The lube stopped the squeak but I am sure that the pump bearings are soon to go.

If you do not have belt dress for the serpentine belt then rub some soap (bar) on the belt and see if the noise stops . The belt can be tight and even new and can make noise:beer

check the idler and the tensioner pullys along with the belt. both replacements are metel and not plastic. the run around 10-16 dollars for the pully and 40-60 for the assembly. I work at a parts house so the prices are pretty accurate, but the diagonosis is a suggestion only.
