Hey guys, it's been awhile since I've posted on here and last thing I posted about was my transmission problem (which is now fixed, thankfully) but I have run into another, less severe problem. The truck squeaks at around 3000 rpm and I've been told it might be an idler pulley or other sort of pulley problem. I looked at the truck today and noticed that the belt moved forward a little on the water pump pulley. Does anyone have any suggestions or comments or advice on what it could be and what I should do? Any input would be great.
