newbie, a few general questions...
 
i just bought a 1987 wrangler laredo a couple of weeks ago. its been sitting for a few years, so i am wanting to freshen up fluids and do some tuneup stuff before i drive it again. i guess i am looking for input on what kinds of fluid i should use in the transmission (ax-15 i think), transfer case and front and rear axles. the engine was replaced at some point not too long ago (and fitted with an msd ignition system), the seller claimed possibly a jasper, but im not sure, and the front and rear axles were replaced with 94 (?) 4 cylinder wrangler axles... its kind of a hodgepodge of parts. also, i hear the carbuerators are crummy, is there any cost effective alternative to the carter carb on it now? i am a bmw mechanic, i get fuel injection but im kind of lost with carbs. :9lame: thanks for any help or input.

welcome yj brotha.

the 4 cyl axles are a good thing, that means you have 4.10 gears, which is cool.

differential fluid is just 80w90 gear oil, t case is just any ole atf. transmission is gear oil also, but look into that some more, i forget off the top of my head for some reason the specifics, i think there's somehting to stay away from.

i get my fair share of bmw's to work on myself...that carb does suck, they had way too much going on because of emissions at that time.

your best solution is to make it fuel injected. not the cheapest, but way worth while. there's some throttle body conversions, 4.0 head swap, or swap the whole 4.0.

lets see some pics, we like pics.

i had a 91 cherokee laredo until about a month ago when i let my sister borrow it. t bone- game over. it had the 4.0 ho engine, smooth good engine. now a paper weight. my bmw was a four cylinder, now a 6, but i kept the 4 cyl rear, so i know what you mean about "thats a good thing". pics, lets see, i'll put a couple of each vehicle up...

very nice

so you have a donor cherokee to swap in the 4.0 driveline:D or she t boned someone and smashed the motor to?

fourdoorfanatic 05-03-2009 05:52 PM

i wish, she got tboned, i thought by the pics the engine would be okay so i drove about an hour to her city (charlotte) and cranked it at the storage lot, no oil pressure and knocking like a mofo. i guess she got hit so hard it broke the oil pump. she pulled out in front of someone else who was going about 45-50mph. at least it was my jeep and not her accord or she would be hurt instead of a little shook up and sore, gotta hand it to that cherokee, it took a shot. im trying to get pics of it, it was nasty.

i've seen the intake manifolds that mate up to a smaller 4 bbl holley and conversions for the weber 32/36 (which i have like 4 of them at the shop from the 70's bmw 2002, but thaqt seems a bit small, 300cfm?!?)

jpdocdave 05-03-2009 06:05 PM

i still say you have a good option with that cherokee. you can swap the head only if you want, since you have the head, computer and wiring to use the fuel injection, or find just a motor, or short block, and use all the donor parts. its really nice having a donor 4.0, you know you have everything to make it work.

the head swap is practically free with what you have. and it almost bolts up with no mods, i think you have to plug a coolant port, thats about it. there's many write ups and much info on doing it.

...i don't have it anymore. i made it her problem. :doh:

Thanks Jay

what exactly do you want a write up on.

sooboss 05-04-2009 10:40 AM

i just wasn't sure if there was a thread on this conversion.. but i did find a kit from quadratec..

Seems it would be cheaper to get a donor instead.

fourdoorfanatic 05-08-2009 02:13 PM

i just going to go with the webber 38 carb conversion. and yeah, trans lube is just gear oil, got all the fluids changed last night and while starting the engine to recheck the oil level the starter crashed out on me. greeeeeat. more work to do tonight. at least its not a bmw starter, jeep stuff is cheap!! :punk:
