thanks man! gonna make her look good, still haven't came up with a name for her.. hmm :hmm:

huh i'd thought ill be better, if its the same as the 4.0L then the 4.0L would be cheaper in general considering difference in fuel types... and tune-ups. the 4.0L in my old ZJ was a great engine, ran powerful, got around 27mpg at best, mostly interstates/freeways(i rarely go over 60)

the perches are what the springs sit on. they're welded on. you have an ax5 5 speed trans. you will need a new one for it. get one from a '93 or newer jeep 4 cyl so that you have an external slave cylinder. the trans is 21 spline, so you'll want an np242 from an '87-90 4.0/auto cherokee. but you will then NEED a '93 or newer ax5, as the ax5 from that year on uses a short input...and all aw4's are short input. that, or you can put an ax15 5 speed in from behind a '90 or newer jeep (any model), and use an early 90's dodge dakota ax15 bellhousing. this gives you a better trans for towing with. ok thats good, i've got a friend who welds on base for a living so he can help out with perches. the AX15 sounds tempting in case i ever want to swap in the 4.0L in the future. is it gonna do better for the 4 banger than the AX5, the bellhousing shouldnt be hard to get. if i get the AX15 i'd still need the 242 from the 87-90 4.0 auto cherokees?

If you plan on staying with only 31" tires, a Dana 30 front will be fine, there are plenty of parts upgrades, and it will bolt right in. You mentioned a 35 front, possibly by mistake. There was never a Dana 35 front availablke for our trucks, and if there was you probably wouldnt want it. As for the rears, the stock Dana 35 with 4.10 gears will be fine if you don't plan obn much wheeling, but a 44 would be a great upgrade IF you can find one. As for gearing, 4.10 will be good for a 2.5 on stock size tires, but if you want 31's you might look into 4:37 or 4:56 gearing. 4:56 geared axles were stock early on in 4 cylinder automatics, but are EXTREMELY rare, the other option would be to have your axles regeared, but that can be costly and is not meant to be done by an amature. Good luck. yeah i got the d35 part misunderstood, theyre rear axles mostly. d44s are great. and its not if, but when ;) regearing is way too much pain both physically and budgetically, so thats definitely out of the question. i don't even know what size tires are stock lol. it sat on 235s when i bought it, switched my YJ's 225s on it and the speedo is still off(goes 76 when it reads 70)

d44 it is then, extra strength in the back :) d30 front could do good, hope it does fine pulling weight. i'll be using 4.10 gears, theyre awesome all around. perches and transmission I'm curious about, i'd like to keep the 4 banger, which manual trans do i get and explain more about perches(are they bolts?) lol

sounds like something to avoid now then lol glad mine was a 4 banger when i got it, it ran strong after bringing it back from the dead. real strong :cheers:

looking towards the 242, but still need more info on shafts, axles, gearings, etc etc. ideas? just gonna make this less painful as possible and still work on/off the road

tried search, JF, and Google. not much came up, so I wanted to hear from y'all, how is it compared to the 2.5L or the 4.0L? stronger pull? reliable? share thoughts :popcorn:

thanks! i definitely will, gonna be so much fun working on it

here's one pic i have so far, its at my stepdads atm, gonna tow it home soon. and a link how i got my MJ http://www.jeepforum.com/forum/f53/my-n ... j-1151184/

alright its the np242 then, how about axles? anyone thinking i should keep the rear and install a d30 in the front on stock shocks? or redo the whole thing? i'd like d44 in the rear on leafs, and d35s on the front on shocks, itll run on 31s in the future, maybe a small lift. ofc 4.10 gears, gonna be a lil work truck to me :D

yeah i didnt think quadratrac would work great on a small truck. its a great 4x4 system, i loved it in my old ZJ. its all down to selec trac or command trac. I havent showed much interest to commandtrac, i have it in my YJ and its just really simple to me. at least it has the 4lo :D might go with selec trac, more options and better overall. hope its easier than commandtrac :cheers: go easy with the numbers, which NPxxx is which lol

I got a Comanche yesterday, didnt have 4x4 in it. thats good, more fun for me to work on it :D its got the 2.5L and AX5 trans, so I'm thinking maybe commandtrac. I'd really like the quadratrac, that would be a sweet mod but not sure if itll bolt up to my setup, axles will be dana 44 on leafs in the rear and dana 30 on shocks for the front. will be using 4.10 gears and probably upgrade to 31s in the future. what yall think? I'm open to suggestions :cheers: items agreed on... (subject to change) -NP231 Command-Trac -AX5 transmission -D44 rear -D30 front -4.10 gears -31" x 10.50 x 15 tires -etc

sup yall? just came over from Jeepforum.com :) wanted to say hi to yall. this seems like a great forum to join, since theres not alot of Comanche knowledge over at JF. I bought a MJ yesterday, best 500 bucks I've spent. i plan to restore the Jeep overall and put it on 31s. gonna need 4x4 too :) :jump:
