My right side brake drum on my M1028 has gotten the best of me. Axle shaft is out and the locking ring is removed. E brake is off. The wheel would not move by hand when I started on it. The adjuster is frozen and I am letting it soak overnight in PB blast. I was able to work it where I can turn the drum to the rear by hand but not forward. It feels like the shoes are holding it on the top. I can move the bottom slightly when I pull on the drum. Anyone have any Ideas????
