    I have read from an unreliable webpage, about drilling and taping the stock mainshaft from a NP241. Then you can fix the yoke to the t-case and run a rev slip yoke drive shaft. I have a long driveshaft already so I dont want to make it longer with a shorter SYE kit. Has anyone tried this or have input? Thanks.

    Guess that might work but why run the reverse slip yoke? Why not do the drilling and tapping and then wait to pin the slip yoke when you actually break the rear driveline? I am somewhat sceptical about drilling a hardened shaft without causing some strength issues

    I have no input, but decided that you KNOW you are addicted to CK5 when you see the subject "Diy Sye?" and know exactly what someone is talking about.......

    I know it's not a K5 site, try www.naxja.org. There is tons of info about this (I USED to own an xj until I came to my senses).

    Thanks Ill check out that site. I was mostly wondering about the strenth issues of a bolt into the shaft, and if anyone has done it?

    Here it goes, Driveshaft Superstore sells a kit for doing just thing. So yes it is doable. However I think it is stupid.

    Advantages of an SYE:
    -shorter drivline(longer driveshaft)
    -more bearing support of output shaft(=stronger)
    -more travel available in a slip shaft vs a slip yoke


    When you drill and tap the output shaft you eliminate 2 of those advantages. There is no bearing to support the shaft(Just the output seal), and your driveline is just as long. Save your money and get a real SYE kit. Or if you have a 208, a 241.


    And yess, removing material from the output will certainly weaken it. A lot? not likely, you'll probably still break a case or chain before you bust the output shaft.
