OK guys i am lost here.. I have read the 2wd to 4wd info and i can't find what i am looking for so here i am .... what year front axle and 5 speed trans with transfer case would be a bolt on for my 1991 comanche 2wd 4.0 auto trans? Also rubcion rims and tires will they fit ? Thank you for your time :drool:

You will need to swap out your transmission for a 4WD unit (either that or do the research to see if the rear tail cone can be swapped out.) Regardless you'll need another AW4 (either for parts or to swap).

 

Depending on what year 4WD AW4 transmission you find, it could be a 23 spline or a 21 spline unit. (23 spline being stronger) You will need a matching transfercase with the same spline count. My suggestion for a transfer case would be a NP231 over the less common 242. My experience is that the 231 holds up better.

 

The 'non vacuum disconnect' Dana 30 axles would be a better choice for you. I beleve they were from 1991 though 1999 but someone here will need to verify this (unsure of the years).

 

If those Rubicon wheels are 5 x 4.5" bolt pattern they will work. The late model JK Rubiocons are 5 x 5" bolt pattern and they will not work.

Thanks for the help

The rubi rims you want are 06 and older TJ wrangler rubicon. Your best bet would be to find a trans and tranfer case together already. Youll need to find or have made a rear driveshaft too. Just noticed, you want a 5 speed... stay 1990 and newer AX15 from an XJ, YJ, or TJ.... though with the newer models youll have issues with the speedo hookup, and the models from the wranglers may require clearancing with a sledge hammer as the TC is clocked slightly differently. You should also get the TC shift linkage from whatever donor you get the TC from so you know it will hook up right. Good Luck.

Oops, I misread this.

 

I read this as how to go from an AW4 2wd to 4wd.

 

Sorry.
