Turbone Posted April 5, 2009 Share Posted April 5, 2009 You cant do a t-case without lifting, there just isnt enough room. What do you break the most: Axles What is your final Crawl Ratio: Nissan t-case @ 4.37 x 3.9 Tranny x 4.11 Diffs = 70:1 (I think) EA81 or EA82: EA81 What size tires: 30x11.50x15 Amount of lift: Aprrox 8in Locked/open/LSD: Locked Link to comment Share on other sites More sharing options...
mcbrat Posted April 6, 2009 Share Posted April 6, 2009 This should be your crawl ratio Rob... Soob 1st Gear * Soob Low Range * Nissan Low * Axle Ratio 3.545 * 1.592 * 2.000 * 4.110 = 46.391 Link to comment Share on other sites More sharing options...
Turbone Posted April 6, 2009 Share Posted April 6, 2009 This should be your crawl ratio Rob... Soob 1st Gear * Soob Low Range * Nissan Low * Axle Ratio 3.545 * 1.592 * 2.000 * 4.110 = 46.391 Ah, right. I was using the final gear ratios on the tranny & t-case. Thanks Mick......I preferred my first ratio tho. Link to comment Share on other sites More sharing options...
bigo1966 Posted October 6, 2009 Author Share Posted October 6, 2009 Bring up an old post. What part of the axles break the most? What about the stub shafts on the rear diff. Im trying to get an idea of a 90:1 low ranged subaru and welded rear end what im going to break the most. This way i can plan for the next upgrade.

monstaru Posted October 6, 2009 Share Posted October 6, 2009 (edited) after you get past breaking axle cups, you will break diff stubs .then you will spin axles themselves.if yo uhave the axle shafts cryo'ed, you will move onto something else. it has been said before,"what would you rather break?"something you can carry a couple of, or something you have to fix when you get home? before evans creek, i had only blown cages in axle cups,bent a control arm, and broken shocks. that was all on jobsites.oh yeah, i had broken an exhaust stud by landing on an exhaust runner(i had a skidplate the next day:lol:) your next upgrade should be to another diff, but then you will break drivelines, and u joints.specifically speaking,the r200. don't get me wrong, i come from a mud background.fast and dirty ya'know,but am learning the way of "less go more slow"......well, at least i am trying. cheers, brian Edited October 7, 2009 by monstaru Link to comment Share on other sites More sharing options...
bigo1966 Posted October 7, 2009 Author Share Posted October 7, 2009 Well once I go through my 2 rear diffs and all the rear axles I have stocked up I might do what SJR is doing with his solid rear axle. What about the datsun diff and axles with u-joints? Arent those axles stronger? Is there a swap for us to that rear end and those axles? Link to comment Share on other sites More sharing options...
monstaru Posted October 7, 2009 Share Posted October 7, 2009 the 510 axles are not stronger.... i am STILL waiting to hear from my friend at the machine shop.but when i do , that was the direction i was going. u joints. with slip sections, like drivelines. cheers, brian Link to comment Share on other sites More sharing options...

3eyedwagon Posted October 7, 2009 Share Posted October 7, 2009 Or you could just save yourself all the torment, and go buy what you really want, or think you'll utilize. If you really want to do alot of wheeling; do some research, make an informed decision, and be happy with your final product. If you want a neat parlor trick of a vehicle, that is mostly a conversation piece, you spend most of your time wrenching on, and enough money to actually go buy something capable of multiple trail trips; then bastardize a Subaru.... The juice aint worth the squeeze man. Just admit it, and get a pickup. Or Jeep. Flame away, but, I'm right. Link to comment Share on other sites More sharing options...
monstaru Posted October 7, 2009 Share Posted October 7, 2009 ya know, bigo thought i was flamin him when i said that he was regressing a while back.i spoke to soon.i feel he is moving in a good direction here.i think the light weight , very low gear combination can be deadly in the sticks and rocks...which = fun......... i think that some of us just want something to do,and we like our cockpit.i mean what good pilot hates his cockpit? in closing, i would like to say that, i suffer from the same affliction, and things can be done well enough to not warrant immediate attention from the wrench. if you wish to take shortcuts, then yes, by all means you do end up polishing the handles on your wrenches ....... but to each his own.......cheers, brian Link to comment Share on other sites More sharing options...
TheSubaruJunkie Posted October 7, 2009 Share Posted October 7, 2009 There are two types of people; Those who want to follow, and those who want to lead. It seems this forum has the pioneers who want to do stuff that hasnt been done before. Of course, we all could just go out and drop $3,000 on a ready-to-wheel toyota, spend weekend after weekend bouncing off rocks, camping & having a great time. Or, there are some that want to spend days & weeks in their shop building something with their own two hands. Breaking new ground & proving the nay-sayers wrong. I bought a Toyota, These guys want to build a subaru. I agree with Brian, "To each their own." Back to the subject at hand. I think everybody here can agree that a Subaru's weak points are its CV axles & differentials. Beit the shafts or the cups... something is bound to break in that area. If you ask me, i believe the rest of the subaru drivetrain is bulletproof, and if someone could figure a way to replace those weak links, than anything is possible. Unfortunatly nobody has the shop to do the propper R&D, and it looks like the only person here to have spent time with a machinist on the matter is Brian.

mcbrat Posted October 7, 2009 Share Posted October 7, 2009 i think that some of us just want something to do,and we like our cockpit.i mean what good pilot hates his cockpit? yup. I like the interior of the Brat, and you sit nice and low.... Of course, we all could just go out and drop $3,000 on a ready-to-wheel toyota, spend weekend after weekend bouncing off rocks, camping & having a great time. I thought hard about that route.... would've been way cheaper, but the Brat build gave me something to think about how I wanted to put it together, even if I couldn't do the fabwork myself... and my wife encouraged the build up of the Brat!

bigo1966 Posted October 7, 2009 Author Share Posted October 7, 2009 I like the subarus cause they are different. I dont really care for off the shelf stuff and bolt it on. The sedamn looks sick with 32, its not another sami or jeep. Im guessing that the splines on a VW CV dont match up to the splines on a EA-82? Or what about 930 CV's? I might be beating a dead horse but its my turn to beat it!!! Good news is i started to put the ST1100 motor in the subaru. Im having to cut most of the front end off then ill rebuild it like the buggyroos or something. Link to comment Share on other sites More sharing options...
Uberoo Posted December 19, 2011 Share Posted December 19, 2011 I know this is a old thread but I just want to throw in my two cents: What do you break the most and why:rear axles What is your final Crawl Ratio:46.391 EA81 or EA82:EA81 What size tires:31x10.50x15 Amount of lift:8" Locked/open/LSD:Locked/Fozzy Locker one of the really neat things about lifted subarus aside from the looks you get is there low center of gravity.Even though I am roughly a foot taller than stock I can take lines over obstacles that a conventional lifted truck/jeep would roll on.With my subaru being small and nimble and the low center of gravity I can take some very interesting lines through something and still be able to maneuver around things. when I first lifted the car I was constantly blowing the rear axle cups-atleast one per outing.Now that I have legacy DOJ's everything is holding up,but the last outing my engine blew.I swapped in a EJ22 now I kinda feel like I am uncharted territory as far as breaking stuff because I haven't had time to get it running yet.
