...or am I just sheltered. Took the shafts out of my 10blt today and I was suprised. Is there no seal or bearing on the inside of the inner "c" thats welded to the tube??? I took em out and there was a few mud chunks in my axle tube and my shafts were rusty almost to the inner seal on the carrier. Also, did gm not make their own shafts? I took mine out and they say Spicer on em. One other thing... recommedation on part numbers for upper and lower balljoints. I would like something greasable.
