Pulley swap
I have a '99 Ranger, 3.0 liter V6, A/C, and am about to swap my idler pulley. I've noticed extreme squealing (shrieking?) during startup, getting quieter but never going away. When checking out my serpentine belt, I noticed the idler pulley is very wobbly.
It's one of the topmost pulleys, I have both the Chilton and Haynes manuals, and the job looks pretty straightforward, but I've never done this before. Do I need any tools other than sockets? Does anyone have any advice, pointers, or warnings?
I've done a forum search on pulleys, and read a recent thread that makes me confident that a new idler pulley and belt will fix the noise. I'd really appreciate tips from experienced mechanics to make this a painless job.
