I've been here in Guam now for a month, and my 96 F250CC 4wd w/460/AT has developed an irritating condition: Whenever I use the AC (almost always) a squeal comes from the front of the AC compressor. AT first I thought the drive belt was loose, for that was the sound it made. Then the more I tracked it down, the more it sounds like it's coming from the AC compressor. Actually, it sounds like a cross between crickets chirping and a squeal. It's much worse after a rain. When I start the rig and don't use the ac, it's rather quiet, but still there. When I turn on the ac it becomes rather pronounced in pitch and volume.
Question: Is there a bearing going bad in the compressor? Can I use some wd-40 to get rid of this sound?
Your replies are appreciated.
Thanks,
Harry in Guam
