Title: squeeling noise??
Post by: 81chevyskullc10 on November 07, 2011, 02:24:56 pm: I bought this truck 2 months ago and I also posted a issue about my power steerig bracket and how it squeels when romp on it. My altenator went out so I replaced it. Now the squeeling is there not stop and it sounds like it is coming from my water pump. I do not like the V belts but i do not have the time to go to the junk yard and obtain a single belt system or the money. I noticed the waterpump pully is wobbleing as it is turning. Any suggestions on this ( I imagine I need to replace Water pump because when i start truck up it continous to keep squeeling until i put it in drive, then when i stop and shut motor off it will making a squek noise also, any help will be great

replace the pump?

You stated your water pump pulley is wobbling, I made an observation that it should not wobble, therefor fix it by replacement of either the bent pulley or the shaft on the water pump is bent, therefor replacement is in order.
