So Mark, what did you do? I've noticed that I hear a squeek anytime I drive in rain and then park overnight. When it first starts up I hear the squeek, but after a while it goes away. I'm suspecting the bearings are going dry and there probably is a very slight overnight corrosion that gets worn away after that little while. It's been that way now for about a year. I wish there was a way to lube those bearings, but I don't know of any. The guys out here used to add grease to their sealed bearings on the John Deere combines by using a syringe and needle filling it with grease and puncturing thru the seal and injecting the grease, my nephews say they have kept old bearings running for many years by doing that, seems the rubber or neoprene seals seem to reclose after you withdraw the needle. I've never tried it, but they swear it works just fine.
