    Yes, the axle shaft has to come out. If you've nver done that before be warned that that part of the job can be way over half the fun. There's a short tube that has to be seperated from the steering knuckle to permit the shaft to be pulled out. Liberal application of a BFH will get the steering knuckle off after you get the castle nuts off the ball joint stems. A special tool is needed to R & R the adjusting sleeve inside the upper mounting hole. You need a torque wrench to adjust the sleeve and set the proper load on the ball joint stems. Overall it's not a really bad job, I think it flat rates for 4 hours per side. While you're in there check the axle u-joints and replace them if there is any hint they might be going west. When you put the stub tube back in the steering knuckle clean the mating surfaces up real good and swab it well with anti-sieze lube, that will pay off the next time you have to open it up.

    If you decide to do the joint replacement your self good luck finding the socket for the adjustor sleeve at a local store. Hopefully you'll have better luck than I did here in San Antonio. I had to order mine on-line from Snap-On. Guess I could have flagged down one of their trucks.

    When you do get to it, the bottom ball joint gets torqued to spec first then the threaded adjustor sleeve gets installed and torqued for the top joint next, and finally put the castle nut on and torque. Alan gave me this info and it sounds like it's the way to go. I'm doing mine tomorrow and will be following his advice.
