My truck is making a loud winding nose when the truck is on and the noise gets louder when I press on the gas. I was told it was the lower pulley on the a/c belt. I keep getting told to take my truck to the dealer to get it fixed because it is a tricky thing to fix. What is involved on fixing this? I was told that the bearings go out on those pulleys.
Do you
have the same problem?
