I have a Buck 28000. I know it is ancient but it was free. The fan the other night started squealing. I took the fan cover off last night and shot some WD-40 in it in hopes that would resolve the problem. It helped a little but the fan seems to almost be stuck and once it starts spinning good it is making a horrible noise. ANyone have any ideas on what it might be. i need to really pull it out this weekend and take a good luck. Just looking for suggestions before I do.
