I am thinking that I should take the wheel off and build a little dam around spray Penetrating oil and let it sit for awhile. Not sure I want to apply heat because of the seals. Any other ideas?

You could try a cordless 3/8 drive impact with an Allen wrench socket. Make sure and wedge the hub so it doesn't spin. I feel for you any method your only likely to get one shot at it. However if necessary you could drill and recap a new set screw. Good Luck

Kroil first, a couple of applications. Then a stob of an allen wrench that fits and tap tap tap with a small hammer. Kroil it again and tap it the next day. Then a prayer and try to remove it.

the problem I have with drilling is metal filings in the hub

A impact driver you hit with a hammer probably best choice .

Never heard of Kroil so I did some research. Kroil vs. PB Blaster threads are like Ford vs Chevy.

Kroil is good stuff. It’s on every Gunny’s bench. I don’t know exactly what you’re working on, but if it will fit in a bucket, kerosene and ATF will soak it loose, guaranteed.

I t is a set screw on the axle hub. I wont be soaking it. I will have to build a dam around it and cover the screw with Kroil or PB Blaster. Will probably be PB unless I can find Kroil local. I was headed to Buchanann this weekend but that may be off so may have a chance to work on it. I just want to check the oil in the hub. No leaks so I am sure it is fine. I had a leak on the front one but it turned out the set screw was not snug.

On an axle I would hit that little sucker with a propane torch. The axle is a great heat sink. Add wet rags around the set screw and heat it up.

thought about it but the hub has rubber seals so need to be careful with the heat.

An oxy/acet torch is the proper tool. Small hot flame will heat the screw and threads quickly without spreading. Wrap wet rags around the axle exposing only the set screw area. Keep the rags wet. Get a dull red, take it out, check the lube level, put it back using silver or nickel anti seize. Go fishing. Don’t sweat the seals, the water will carry away the heat. This is an old A/C man trick.
