Having the motor out and doing much thinking I decided to take things further with this build.
SAS and Doublers!
I pretty much maxed out the use out of my IFS. Having Rubicon Trail, Fordyce, Slickrock within an hour drive from me, it would be nice to have a rig more capable to flex and crawl. Also Im fed up with the fact that we almost have no options for good low gearing.
For the axles Ill be using a Dana 44 from a early 80s Jeep Wagoneer. WMS to WMS is 60.5 inches. Ill be keeping Montero rear axle (at least for now) which is around 59'. As far as the cases. Ill be using Duffy Box4Rocks kit. Chopped NP231 out of a XJ Jeep in the front. Still deciding on what to use in the back. It will be either a NP241 or a flipped Dana 300.
If I use the NP231 and Dana 300 my low gear will be something like this.
2.72:1 or 2.62:1 Low
7.12 LOW LOW:Wow1:
Much better than the lousy 1.9:1 that I have now.
Anyways, along with the build.
I removed the transmission along with the case using my floor jack.
Bolted all together it measures 45' inches! Stock Montero Transfer case is monstrous. Im thinking the doubler setup will be close to that length, maybe even shorter.
Full size Monteros use a Aisin 30-43LE (a.k.a. A340F and AW4) automatic transmissions, similar units are found in Cherokees. To mount a six bolt case to Monteros transmission Ill be using a tail shaft housing from 1998+ Cherokee 4.0L automatic . After some time I finally sourced a 1999 Xj at a local PicknPull.
Luckily when I got there someone already partially took it apart so I pulled the tail housing in no time.
Hmm, looks familiar
To make this work I also need the Jeeps pulse gear for vehicle speed sensor. I grabbed that along with the sensor.
Also while I was at the yard, I got a non sunroof headliner from an LS. Ill be welding my up shut. I really see no point in keeping it. Truck has a cargo rack, motor pretty much doesn't work, it leaks when it rains and it weights a ton. Should be nice removing all that weight from the top.
Total spent: $20 for headliner, $33 for tail-hosing.
