4wd conversion questions


Recommended Posts

- 4wd transmission that matches your engine's bolt pattern

- t-case that matches your transmission's spline count

- Dana 30 front axle that matches the rear axle's gear ratio (not necessarily what you have now, but they have to match)

- front driveshaft of the correct length

- rear driveshaft of the correct length

- all the t-case shifter assembly stuff (don't forget the little linkage pivoting bracket that attaches to the underside of the body)

 

Cost is entirely dependent on you. Some guys have purchased whole vehicles for $200, other's can spend thousands building up the individual parts.

well finding a 4.0L with 4wd over here is almost like finding a needle in a hay stack. it's possible, though there aren't that many listings, especially within a reasonable price range and stock without any lifts or other mods that would bring someone to increasing the price. but anways, i found an '89 mj over in portland, oregon for 950$ but it doesn't have 4wd.

Myself, I prefer to pick and choose the parts. That way I get the best of the best, rather than simply what Jeep used back in the day. This is what I have in my 90 (which technically was 4wd to begin with, but I've replaced everything but the engine and trans):

 

--97+ Cherokee Dana30 (because it has the bigger 297 joints on no CAD and is new enough that a complete overhaul wasn't necessary)

--MJ/XJ Dana 44

--95+ bellhousing for the AX-15 (external slave)

--NP-242 t-case (for fulltime capability)

i am looking at these two mj's right now.

http://boise.craigslist.org/car/529915824.html

 

i am waiting to see what the one in boise looks like before i make a decision on that one. first of all i have to sell my truck first, hopefully i can do it before either of these guys sell these mjs. i would like to get the one in boise so i don't have to deal with converting. and i would have some money to fix anything up that needs to be. plus it's a long bed and that's a must for me for my future plans. the difficult thing is trying to find a canopy that fits the damn thing.

do any of you guys have any of this laying around. if you guys do you should put a price on the items so i know what i would be working with.

BTW.. you do NOT NEED a Mj to do this!!! Look for XJ's!!!

 

 

Cheaper and WAY WAY more plentiful!!!

exactly

 

 

all parts would be $500 MAX if you buy a similar year and transmission-equipped cherokee.

 

the ONLY thing that would be different then, would be the rear driveshaft. and that will cost $90 or so to get shortened.

GOOD CATCH PAT!!! :cheers:

 

Yea the XJ drive shaft for the rear is different legnth. But as Pat said, you could get yours shortened (Likely locally) pretty cheaply.

 

:D CW

 

thanks

 

a tip;

 

use your comanche shaft and have it shortened. having a shaft shortened is MUCH cheaper than having one retubed (i.e. having a cherokee one lengthened)

just looking into it. i am working out a decision between two different mj's right now. one of them doesn't have 4wd. better shape than the one with 4wd but more money is wanted. think i will get the one with 4wd already and fixer up.

Depends on the motor, tranny, and packages.

 

Generally speaking, Jeeps did this.

 

4.0 + 5 speed = 3.07

4.0 + Auto = 3.55

2.5 + 5 speed = 4.10

2.5 + 4 speed = 3.55

2.5 + auto = 4.10

 

Not sure what they did with the 2.8, but I know 3.73 was also an option. Just look at the tag on the diff. If all it gives you is gear tooth numbers, take the ring number divided by the pinion number.

it's not in my hands yet. but the guy is keeping it for me until i can pay it off. so it will be mine here soon. a friend of mine is getting me a job working for the carpenters union and i believe the wages are around 20+ dollars an hour. he said i will be worth up to 10 hours, but only four days a week. which is fine with me.

 

like i said. i am trying to get all this info gathered up now.
