Hi all, I'm kinda new at this 4x4 thing so bear with me. I'm in the process of doing the front brakes and greasing the hub bearings. Well brakes are going fine. But after removing the hub assembly, the part with the needle bearings in it that I'm going to regrease. I noticed the seal that goes into the axle past the U-joints is flopping around. I can also move the axle around about a 1/2" or so where it goes into the axle housing. Should I be able to move it? The U-joints seem to be fine along with the ball joints. Any thoughts, suggestions should these seals be replaced while I'm in there? Thanks edsaws
