On the 91 p/u I recently acquired, its def coming from the top end, somewhere at the front, I'm thinking number 1 or 2 idler pulley bearings...I say that because the p.o. got this stuck in a deep hole, the same exact hole that I got my 93 runner stuck in this spring, and its making the same noise, just not as loud. The truck did sit for 2 years after.
Anyone have thoughts? Where could I get those pulley bearings cheap? I had to buy the whole bracket for the #1 pulley bearing on my 93 a couple years ago, and the only place I could get 1, was at the stealer...it was $600!! So I'd prefer not to go that route.

 

agree with the bearing, not sure where exactly though...

 

Hard to hear over the air noise from the fan but it might also be the water pump pulley bearings since it seems to get a little louder near the middle and thats where the pump is...

 

Ya...Im hoping its that or the t-belt #2 idler pulley.... I HOPE its not a cam bearing.

 

When I replaced my HG I changed bought A pack of things off ebay all for $90 included was the waterpump, ideler pully, tensioner pully, and timing belt.

 

were they new, or used? I would prefer to go with new, so I'm not in this same boat agian down the road.... the up keep on 3 yotas and 2 other cars is starting to affect the wallet, and fishing/beer drinking time..lol

 

Narrow it down with this, no tool box should be without one. $12 @ Napa:
