jage Posted June 29, 2006 Share Posted June 29, 2006 Ok, I've been losing sleep over this. I need to upgrade the 30/35 XJ axles I'm planning to put on my MJ build up and I keep thinking UNIMOG. Specifically Exaxt.com disc converted axles. I figure- high range, AX5, on 38s using 2nd-3rd-5th will be close to using 1st-2nd-3rd on my TJ which has 3.73/32s. Can the 5th gear take it? I know you're not supposed to use 5th offroad, but at highway speed? The second factor is that I'm sportin a 2.5L. I don't think power won't be the issue but top-end speed and high RPMs will (thinking 55mph at 4-5K i need to look at my TJ again). Not really sure, it isn't like thinking about the diff between 4.10 and 4.88s. The axles would be driveshaft driven instead of torque tube, sported on an 8" Skyjacker Rock-Ready XJ suspension. And it's meant to be a trailer queen, but that doesn't mean it will never see pavement. So.. stupid waste of money? Problems I haven't considered? Any and all opinions are welcome. It just keeps rattling around my head- if I'm going to save $$ for axles, why not save for unimog axles? :nuts: Link to comment Share on other sites More sharing options...
Cooter Posted June 29, 2006 Share Posted June 29, 2006 So- You're planning on a 8" lift in addition to the 5" the portals will give you?? Link to comment Share on other sites More sharing options...
jage Posted June 29, 2006 Author Share Posted June 29, 2006 Ah see that's exactly the sort of thing I hadn't considered. You think 13" is too much for 38s or 40s? :nuts: I suppose I could use 6" springs instead and it would be 11". Link to comment Share on other sites More sharing options...
yj2mj Posted June 29, 2006 Share Posted June 29, 2006 Way too much lift. I wouldn't go more than 2-3" of lift, do a set of long arms, and cut the fenders. Portals alone are going to sit the jeep 5-6" over stock. Link to comment Share on other sites More sharing options...
jage Posted June 29, 2006 Author Share Posted June 29, 2006 Oh well. Should I just go with D44s then? Link to comment Share on other sites More sharing options...
yj2mj Posted June 29, 2006 Share Posted June 29, 2006 Hell no, go w/ portals. If I was going to do it, I'd get the axles, mock them up under the jeep, then decide how much lift you absolutely have to have. Link to comment Share on other sites More sharing options...
jage Posted June 29, 2006 Author Share Posted June 29, 2006 Yeah execpt I have this 8" skyjacker lift thats been sitting in my garage and I'm not good at selling things. So like around 3" in the front and 3" in the back, keep it SUA. I can't believe I'm still considering this - you people are supposed to be talking me out of it! :D Link to comment Share on other sites More sharing options...
Cooter Posted June 29, 2006 Share Posted June 29, 2006 Are you getting them narrowed? If not, I forsee some oilpan clearance issues. Also, the extra leverage from the portals will dictate a custom suspesion. Link to comment Share on other sites More sharing options...
yj2mj Posted June 29, 2006 Share Posted June 29, 2006 So like around 3" in the front and 3" in the back, keep it SUA. :D Exactly, spring under will help fight axle wrap. 2-3" in the front w/ custom long arms. Link to comment Share on other sites More sharing options...

Also, the extra leverage from the portals will dictate a custom suspesion. Limit your uptravel before it would hit. I would think narrowing them would make any clearance issues worse.

jage Posted June 29, 2006 Author Share Posted June 29, 2006 Narrowing one side might shift the pumpkin... exaxt.com doesn't say anything about that. Link to comment Share on other sites More sharing options...
DirtyComanche Posted June 30, 2006 Share Posted June 30, 2006 They're not centred stock, if you narrow them they will be. Unless they cut more off the narrow side. These would be 404s, that is? Of, if you're swapping in portals, you might as well link the front and rear. Link to comment Share on other sites More sharing options...
pingpong Posted June 30, 2006 Share Posted June 30, 2006 If you asking us what you should use.... I think you need to give me your money.. and I will show you how to spend it :banana: To answer your question.. Moogs or d44's :thwak: what were you thinking when you asked that question.... Rockwells :banana: Link to comment Share on other sites More sharing options...

feerocknok Posted June 30, 2006 Share Posted June 30, 2006 There's a Unimog Wrangler being built in town on 44s and coilover front and rear. It's impressive. Don't know where, but I heard Unimogs lift 11"? Also, one of the benefits of portals is incredible ground clearance. See where the axle housing is in comparison to the wheels? That's portals! To do leaf under (or leaf at all) takes out a big reason to put these axles on. While the axles are impressive, keep in mind, it'll be a b*tch. Also, parts are hard to get on this continent. Sure would be wicked though. Link to comment Share on other sites More sharing options...
87manche Posted June 30, 2006 Share Posted June 30, 2006 not to mention weight, how much do mog axles weigh? 4-500 pounds? Link to comment Share on other sites More sharing options...
jage Posted June 30, 2006 Author Share Posted June 30, 2006 The problem I assume with doing spring over on an MJ at 3" would mean getting flatter springs. I don't really see how doing SUA loses that much considering that 5" from portal -2" from SUA still gives you +3" over the same point on a non portal axle with SOA. Given the need to use drop springs and propensity for axle wrap I think doing SUA and gaining 3" or so would be worth it. And the pumpkin wouldn't hang any lower with SOA or SUA. Besides it's only in the back. :banana: I think, considering my current parts pile and the state of my project I'm going to go ahead with the 8" build up and get a feeling for how tall that will be, then I can have a better idea about what height unimog axles will get me to. At the least it will be an excuse to buy another MJ in the future. Link to comment Share on other sites More sharing options...
yj2mj Posted June 30, 2006 Share Posted June 30, 2006 not to mention weight, how much do mog axles weigh?4-500 pounds? I'd guess more around 6-700lbs. A dana 60 stock weighs in around 650. Link to comment Share on other sites More sharing options...
jage Posted June 30, 2006 Author Share Posted June 30, 2006 The mog 406 axles weight around 700lbs each - "more than a rockwell" as they say. I'm not sure how much the 404s weigh exactly, but I'm sure it's somewhere on google... Ah... http://www.teximog.net/axles.htm 1100lbs for a set. About. I have no idea how that compares to 60s, 44s, or 9"ers. What's a few hundred pounds here or there? :D Link to comment Share on other sites More sharing options...
yj2mj Posted June 30, 2006 Share Posted June 30, 2006 Don't worry too much about the weight, atleast it is unsprung weight, won't make it anymore unstable. Link to comment Share on other sites More sharing options...
pingpong Posted June 30, 2006 Share Posted June 30, 2006 Thw whole purpose of Moogs, are the strength and the ability to have a lower center of gravity. For roughly the same money you can get 2 steering rockwells for the price of one moog axle. it is also easier to narrow a rockwell. Only major disadvantage to rocks is the lack of ground clearance, but that can be achieved by running some 44's :brows: Anyway you are looking at it... back away slowly and give me your money and I wil show you how to build a Mog MJ, or one on rockwells for you Link to comment Share on other sites More sharing options...

DirtyComanche Posted June 30, 2006 Share Posted June 30, 2006 If you're going to take the time/money to make MOGs works, at least build a better sunspension setup. I doubt it would be hard to 4-link a 'manche rear, or run a 1-link if you want it to be really easy. To mount coils or 1/4 elliptical leaves, you'd probably have to cut a bunch of stuff. That's a good thing. Link to comment Share on other sites More sharing options...
