    Oil in compressor dryer too? Just thought pag oil was added to the compressor. Has to be a certain amount mine was already added. Spray something on the belt and see if it stops?

    None. Bone Stock. EXCEPT: Brushguard, tow hitch, both welded to the frame. It's good to have friends and a fully equipped garage!
    Could be the belt tension is a little loose, and/or the idler pulley's bearings going bad. Easy enough to check, just take the belt off and turn it by hand. Feel for grinding, or looseness/play of the pulley. The pulley is pretty easy to remove from it's mount.

    The pulley bearings are readily available, both installed in a pulley, and out by themselves, that you have to press in. Again, easy process.

    Good luck, and keep us up to date

    How do you know it's not the belt?

    If it's a new belt, it takes 2 more attempts at tightening to get it to stop squawking.

    If it's an old belt...at least one more attempt.

    Oil circulates throughout the system, so it would make its way to the receiver dryer also. I just watched a professional yesterday put oil in the servicing port using an oil tube in a gun with a coupling attached to the servicing port.
