Thanks for the vid …wondering if we could get an Update about the install/ driveshaft process, or a demonstration of it in action?
Take care;)
Awesome video man💯🫡 im working on the same setup, but a vf4 and this video answer all my questions. Again, keep up the great work and hope to see another that covers how you did your floor for the shifters.
I've been looking for something like this for a while. Thanks!
Would be cool to have a follow up on how your install went in the Tacoma and your thoughts on the ecocrawler and double low.
Very good video, I learned a lot. Hopefully I'll finish getting mine together this weekend.
Rad video man. I’ve been waiting to see this exact video since they announced that were coming out with these and really wanted to see this
Thanks. Felt like a tough video to make, since it's a lot to cover and kinda boring. But I was sure someone else would want to see how it went together.
Awesome video! When will you have a follow up video on how the dual cases performed on the trails
Thanks for the encouragement dude! I’ll be tackling this task next year.
By the way @travis’ shop do you happen to have the donnor part out that 3rd vf2 transfer? Just looking to see if I can get donnor parts instead of having to get a full vf2. Cheers!
Great video, thanks for making it.
This is really handy, just to understand the various features and of the ecocrawler and the shifter.
Would love to see you come out with a video showing it in real time. Would love to hear how it sounds and what the ratios look like while crawling not just on paper.
Awesome video man! Well explained, gives me confidence to put my cases together
Thanks for watching and the nice comment.
How do you identify if it’s a vf1 2 or 4? What 2 did you use?
@@charliesfowllife2335 that's a tough question to answer. I used VF2 cases. Both were manual shift from 3.4L V6 vehicles. My understanding is that all chain driven cases are in the VF family. I think that the VF 1, 2 & 4 have to do with it being a 4cyl vs 6cyl vs 8cyl or all wheel drive vs 4wheel drive. You will have to do some research on your own to get better info..
You can find some more info from the website about these eco-crawler cases in this link: northwestfab.com/products/ecocrawler
@@Trav74r does it matter if it’s a 5 speed or auto trans? I have 2 chain driven cases both out of 98 Tacoma’s with a 5speed. I guess they are vf2? I have been looking for info all over. I’ll check out that site thanks!
@@charliesfowllife2335 No that doesn't matter, cases can be used from a manual or an auto truck. My understanding is that there are couple internal pieces missing in a push button 4wd case (what I took out of my truck) that are in a manual j shift transfer case. I believe it's the internal shift forks, as the push button is actuated from a electric motor on the back of the case, instead of the shift handle in the cab.That's why I used two j shift cases. So that may be a thing to watch out for. Also be aware that cases from a 2.7 cyl are 21 spline input vs the 23 spline behind a V6. So that may matter depending on what you are bolting it to.
If you are interested in this dual case setup, the guys that make it are very helpful and knowledgeable as well. I spoke with them on the phone a few times before I ever ordered.
So good
Still wondering if you still have the donor pieces of that other t case that you didn’t used. Cheers!
Wondering how the clocking came out when installed in the truck? Did you have to beat the floor with a sledge at all to get it to fit? Any feedback would be helpful as I just ordered and will be trying to go full clocked as you did. Thank you 🤙🏼
So you need two transfer cases to make this work, plus the stuff from NWF? I thought you needed one transfer case (the one in your truck) + the NWF stuff = dual transfer case…?
Yes you need the planetary gears from an extra case to go into the NWF housing.
Do you have a body lift or did you have to hammer the transmission tunnel to make room ?
Awesome video, thanks for being the first to get this info out there. This is definitely on the wish list.
Semi-related, you mentioned the push button tcase in your Taco, how did you trick the ECU to think you’re in 4 when you did the SAS? I have a push button in my 4R that I’m about to SAS and I’m trying to think of a way to get the ECU to “see” the front actuator/sensor. Just splice in a relay maybe?
Thanks for watching. Honestly I didn't do anything. Just left the plug for the old front ADD system disconnected. So for a long time I didn't have a 4wd light come on at all. The actuator on the back of the t-case still engaged, just no light confirmation on dash.
@@Trav74r Solid. I’ll burn that bridge when I get to it but at least I know it’ll work until I figure out a solution. Your series on the SAS has been super helpful, much appreciated for posting the process
You have to remove the computer and hook up a relay in its place, at least that’s what I had to do. Was able to get 4wd and dash lights to work. Lmk if you want me to tell you what wires I used.
@@christophergoodwin6846 Yeah man I'd appreciate any insight if you've done it
@@jmik09 not sure what year you have, I’m running a 2000 limited (wire colors might slightly vary from year to year). Here are the wires I used: grey, green w/ red strip, light green, green w/black strip, green w/white strip, black w/ white strip, and black w/ blue strip. These are wires all going to the computer in the driver side kick panel, you have to remove the computer to do this. If you’re just trying to make the lights come on the 2x wires for the lights are green w/ black stripe and green w/ white stripe, I think the wire that actuates the add is the grey wire. If you have a different year and your wire colors are different I highly recommend just looking for a wiring diagram and deciphering it.
Hi mate is it in the hilux yet
Did you have to do anything to your synchros when re-assembling the case? The insctructions call for removing them or aligning them before putting the case backtogether but at 35:38 you slap it together with no issues.
Didn't do anything particular with them, they just go back together fine.
Thanks for the response, I am gonna ignore that part of the instructions then and try to put it back together without touching the synchro's, that seemed like an unnecessary portion of instructions @@Trav74r
How would the shifting work on a 3rd gen tacoma with an electric knob style shifter?
I don't know the answer to that. I'm not sure if these cases can be made to accommodate transfer cases from a 3rd gen. If there is a way, it's likely with the rear case being the stock unit. So it would probably still shift with the button/knob on the dash. However you would still need the lever for the front case to be accessible either with a cable or through the floor.
@@Trav74r oh ok cool. The website has the parts for the 3rd gen and you’d use a donor case from a 1st gen tacoma or 3rd gen forerunner, but Im assuming you’d just shift the additional case with the levers and keep the electrical like you said.
What transmission is equipped on your Tacoma
It had the stock automatic, A340F
You ever have any problems with the chain rear case?
None so far. Works as intended and definitely have tons more torque in double low.
Does the northwestfab case need gear oil?
Yes, it has a fill port on both sides and a drain on the bottom. Fill it until it spills out, like most transfercases and differentials.
4cyl has 26 spline fyi don’t ask me why I don’t know it makes no sense
Dual chain cases. Interesting.
Do u need 2 transfer cases to do the eco crawler?
Yes, one for the back half that will get a different input shaft. And a second case to use the planetary gears inside of the billet housing they provide.
@@Trav74r thank you
After rewatching it 3x, I think I'm going this route for my sequoia n using 2 tacoma j shift
@@Trav74r what's the length of the entire transfer case?
@egtallday sorry for the slow reply, the total length of the dual case setup is approximately 19.25". That is from the front mounting surface where it mates to the transmission, to the surface of the rear output flange.
