ThatJeepGuy Posted January 24 Share Posted January 24 Something I've toyed with the idea of a few times and I've even gone as far as to kinda re-invent the wheel to some degree on how I'd make it work. Current fork has 2 purposes, 2wd/4wd and then also high/low range... can it really be that bad to separate those into independent functions? Also gaining the ability to have 2wd-low range. I realize teraflex makes a 2-low fork but at the $350 price tag I think I could do better and also by not adding a 5th position to the already somewhat clunky factory tcase shift setup.

ghetdjc320 Posted January 24 Share Posted January 24 The fork moves on a single rail. How would you propose splitting that into two and what would be the purpose of that? Link to comment Share on other sites More sharing options...
512tr Posted January 25 Share Posted January 25 If you still have the D30 CAD and feel the need for 2WD in low range, you could install a valve on the vacuum line that engages the CAD. With the valve closed (no vacuum) there will be no traction on the front wheels. That clunky factory t-case shift setup could be improved by using this Transfer Case Linkage Kit, I just got 3 kits, for my MJ and other 2 Jeeps.

derf Posted January 25 Share Posted January 25 The internals of the 231 use one solid piece to shift in and out the front output as well as selecting hi-n-lo. You'd have to design a system to separate the two functions. That would mean a new or highly modified case. It's possible. Just nowhere as easy as it is with a fully gear driven case.

I've definitely considered doing this with my CAD as I frequently use low range to backup to a trailer and it's easier on the t case to not bind it up on the concrete driveway. The transfer case linkage kit is a nice upgrade, fiddly to install but much smoother to engage. Link to comment Share on other sites More sharing options...
cruiser54 Posted January 26 Share Posted January 26 Start with an angle grinder? Why not just upgrade to an aftermarket kit? I think having 2WD LOW is just asking for rear driveline issues due to doubling the torque to one axle. Link to comment Share on other sites More sharing options...
ThatJeepGuy Posted November 5 Author Share Posted November 5 Behold! 2 shift forks and 2 shift levers. This is just a 3D printed version for trial and error. This is actually Months old and ik just rather late to this party location. At this point it's just a matter of ripping into one of my spare cases and installing this beta setup to validate my idea. I've been holding off until I have the time and funds to 100% dedicate it to finishing this. If this concept works then next would be bringing it to a few different machinist shops to have it duplicated in steel and also having it hardened which could cost me a bit!

pizzaman09 Posted November 6 Share Posted November 6 Cool stuff. So this separates the range and the high low? Link to comment Share on other sites More sharing options...
