I just pulled my serpentine belt off to check the pulleys in response to a thread I started a week ago. My question is now that I have the belt off should the power steering pump spin like the other pulleys do. It is basically the only pulley that is harder to turn and the power steering has been pretty loud recently. I just bought the truck but was told since the truck has bigger tires(285/75/16) that it will be a little louder. Can anyone give me some quick advice while I have my belt off? Thanks!
