    I don’t follow the op, but does the axel have 17.5 tires? If yes, you’ll have to pull everything.

    No these are 22.5 tires but, it appears I may have to pull the hub, its just a matter of getting the correct tool

    The axle nut sockets come in 6 or 8 point.
    You’ll need a new wheel seal for each hub.

    Is the one on the spider bolted or pressed? Either way you can knock them out with cam.

    Put a collar around the cam, a little heat and pound it out.

    Ive given up for today.......Im just frustrated with it. Didnt know Id have to pull the hub. And even more so that I went all the way to Truck Pro 2x and still got the wrong locknut......So, I sent my wife up there this time to exchange for 8 point locknuts :D:D

    At least ill have all the proper tools to do the job correctly next time. Can someone give me a link to a S Cam Bushing driver install/remove tool

    And also, the tool for wheel seal install?
     
    Rideandrepair and OLDSKOOLERnWV Thank this.

    If you were doing this a few weeks ago I could have taken pictures on how to do it without removing the hub. Couple trailers with pressed bushings
    and never pulled the hub.
    If you're replacing the cam, just torch it off.
