    Why do you want the five speed? I've heard they have issues slipping.

    what axle are you using? links or leafs?

    why not just use the 4cyl trans and transfer case?

    You know what they say...

    if you have to ask you probably can't afford it.

    Seriously though are you doing the work yourself?

    That's what I thought of because I saw some Ebay. Only place I could find it easily.

    Haha yeah but I have I just have no clue what would or would've fit. No im having a shop weld my parts. The 4x4 conversion is for after I have the axle on.

    Well a divorced t-case is one that isn't mated to your transmission, rather it has a short section of driveline.

    So you fab up a t-case cross member and then get your driveshafts made and run the shifter linkage.

    This also means you can run different axles, drivers or passenger side drop as long as you find the corresponding case. Makes it a little easier to choose an axle.

    You can find a divorced t-case or you can find an adapter for a married case and turn it into a divorced t-case. That gives you a little more options and you can upgrade some with lower gears, giving you say 3:1 or 4:1 low.

    You'll have to find ones that convert say a NP ### to a divorced unit. They'll be for specific units.

    Look into a Dana 20 or a Dana 300 or an NP205.

    oh ok, would they just hook up to any tranny? that would all make it way more simple. but i have heard from many other sites that the toyota t case is a tough son of a gun, tho?

    Okay so if you divorce the tranny you can run whatever flange and u-joint adapters to run a driveline from your output to the t-case. Then you run drivlines from the t-case to the axles F&R.

    TRANSMISSION>----TCASE-------------R. Axle
    F. Axle____________


    You could run a divorced toyota t-case as well just find the right adapters and case and you can bolt the adapter to the cone then run a driveline from the output of your transmission to the flange on the adapter of the t-case then from the t-case to the axles.

    Make sense?


    I'm not saying that a divorced t-case is the best way to do it, but it's an option and I would think that it might be a good option for starting with a 2wd trans.

    Also makes it easier to run a doubler since you can run whatever t-case you want to run as long as you find the adapters. So the toyota case is probably a good option for doubler or single.

    My opinion is worth what you're paying me for it.

    [​IMG]

    just to clarify, whatever case you choose there are typically adapters to mate your driveshaft to both o/p of the transmission and to the i/p of the t-case.

    It might be easier to run the toyota t-case as they use a flange. But there are adapters for yokes to flange and from yokes of what style u-joint to yokes of another and there are also u-joints that go from one style yoke to another. Any driveline shop will be able to set you straight with what you need. Basically the most popular cases like the 205 should have adapters to switch from yoke style to flange style, or I'd think. All stuff to research before you buy a case.

    Or maybe it'd be simpler to get a toyota case then you don't need to worry about yoke to flange adapters but you'll probably need to figure that out with your axles. Research before you buy.

    Theres guys who know much more about this than me, so hopefully someone else will chime in but maybe try the solid axle section on TTORA?

    http://www.lowrangeoffroad.com/index.php/dana-60-flange-for-toyota-driveshaft.html


    I guess in the end what I'm suggesting is find the case you want to run, something strong, if you want a doubler make sure you can get adapters to double and then make sure you can get the adapters to divorce the case and adapters for the drivelines (that should be the easiest part). Then you fab your crossmembers, talk to some shops and see what length you should make the t-case to transmission shaft then have it made and have the shafts from your t-case to axles made. Run the shifter linkage, and you should be set. Research research research though to make sure this is the best option. I think it would be based on you can keep your factory transmission which you know is good, and you have more options for t-cases. Research though.

    holy smokes. thank you. now i understand how it all works. i got it with the help of the picture becasuse i have never seen how a divorced case was assembled. yes im doing research and it has been going on for about 2 or so months now. just alot of sites want you to buy their product but barely tell anything about it.

    Yeah I'd just get the adapters for the toyota cases. Divorce one and then double them together.

    OR give marlin crawler, inchworm, and lowrange offroad and give them your specs and see what adapters they have to mate a t-case to your transmission. That may be easier if they have adapters. If you can run an older style case you can run a doubler too. That gives you great control off road.

    http://www.lowrangeoffroad.com/index.php/yotamain/tacoma/transfer-case/prerunner-adapter-kit.html

    I think this would work actually. That would probably be a better option just make sure you make a mount for the t-case with rubber bushings as I believe the factory motor mounts are rubber. They should be able to tell you if it'll run on your truck and what cases you can mount behind it.

    I didn't think anyone made adapters thus my recommendation for a divorced t-case. Either will work but I'd go this way for simplicity.

    Edit: I see you're a 5 lug. I'll admit I know little about the 5 lugs and I'm not sure if you use the same transmission as the 6 lug 2.7 L 4 spds and if this adapter would work. Ask them. Also don't know much about the rear axle, would you be swapping both axles?


    Also, have you factored the cost of parts let alone labor for a swap like this? If you want a quality shop with excellent work check out Stoffregen motor sports in Cool, California. He has an account here.

    yeah that seems to be the path im heading right now. i found an adapter on a ott toyota adapter also. the shop is here in my town and he is buying all the parts and installtion for maybe around 3 grands. i have the 5 lug but i thought either one has the same engine so same tranny too, i suppose. just the front.

    Probably yeah I'm not sure of the width but I'm pretty sure the older SA toys were all more narrow. Look at a LC axle.

    well my update of my research. the older ones were to narrow so i found a dana 30 that was just right, 61". better than perfect. its driver diff and needs steering box. does anyone have a clue or could direct me to the correct steering box for my truck? plus a good transfer case for my truck that is driver. plus the best part is i might be the first in the central valley with a solid axle 2 gen tacoma. lol
