    I finished up my 52 inch spring swap on my 71 blazer and the thing flexes so much I won't have enough droop on my cv. I don't have the shaft bolted to the axle, just the cv, and it binds when I turn it. Granted it is hanging 3 inches below the yoke on the axle. Is there a way to clearance the cv itself? I am pulling the shaft to have it lengthened since I moved the axle forward 3 inches, so I need to know if I should have the shop clearance it, or have them take the cv apart so I can grind it, or if it can be done assembled.

    post pics of the flex!!

    is it a 1310cv? a bigger cv would allow for more angle. maybe try a 99-06 F350 shaft, i just bought one on ebay for $120, which was less than what i paid to have my rear shaft lengthened. just a thought. that way you get a 1350cv, then can get it shortened if needed

    I had mine extended but Did not realize the tolerances on the joints so when I got it back the drive line would bind. I pulled her myself and cut down the contact points on it. it was real easy with a grinder. if they allready have it though, have them do it.

    do you have any pics for comparison on this? so just get one of those and the cv is bigger and allows more droop? not that my truck has massive flex.. my 6" lift shocks are my limiters right now... as if I allowed the truck to flex anymore the d-shaft would come apart... :haha:

    so my shocks are my limiting straps...

    I am going to have some crazy flex, so I need to do something. Question is about that 1350 cv is will it bolt up to a 205?

    There are a couple different 1350 flange pilot sizes,you can turn your yoke pilot down on a lathe if you are using the stock flat flange on your 205.

    Sorry but I gotta throw the BS flag on this one.:crazy:

    If you look in the tech section on the Tom Woods site, it states that the 1350 will go to +20* before any binding, and the 1310 will go to about 30*.
    This is if both CV's are in stock unmodified state, so simply getting a bigger CV MAY make your problem worse.
    Here is the link.

    My front shaft doesn't use the flat 203 style flange. It uses a yoke just like rear that the cv bolts to.

    You running a spicer CV up front? 10 spline front output? You can clearance it, but it will get pretty weak, you may lose the center. I would call up Jess, and chat with him about what you are wanting to do.
