Hi Rick
But this is on the winch?
So you don´t think that lubricating the surface of the tower sections will
work?

And that high pitched squeal certainly sounds like a dry
pulley/bearing/bushing, or a dry metal to metal surface. (Oilite
bearings/bushings don't usually do that.) Quiet to begin with the squeal
building sounds like a dry, tight bearing getting hot with use. If it's
steel there will be some rust powder. Dry bearings are harder to find.
Don't use WD40. Try spraying one bearing at a time with LPS-2. It leaves a
lubricant behind. One at a time will find the specific bearing/pulley
quicker, but that squeal probably means accelerated wear, so shooting them
all with the idea toward replacement might be better for the tower.
73 and good luck,
