well i took that tag to mean that it was a 4.11 in a 2.5 4cylinder motor. and we had poped the cover to count only 36 teeth on the ring. thanks for the tip of not having the front driveshaft in so that I can drive the car, but the thing is that I want to be able to use the 4x4. I am lucky that I do have another car. it's just been a pain in the butt, and I needed to vent about it.

well it turns out that the guys at the junk yard are even more stupid then i thought with just the comment of flipping the axle. Today my friends and I started on swaping out the rear ends. to only have to stop half-way through because the rear end they sold /gave me was the wrong gear ratio. :headpop: they couldn't even read the stupid tag on the thing that said 4/11 on one corner and 2.5 on the other!!!! at least they got it out of a comanche. but they said it was a 3.08. I am so pissed. and now i don't know what to do. it took them a few weeks just to come up with the rear end they gave me. also of course they have the "no cash refund" policy. I guss I will just call them up and b*@$£ them out. it should be interesting. maybe i could get them to give me the front and rear 3.55 axles they have out of a cherokee. but then that means getting a lift kit, welding, etc.

that is why i didn't listen to the guy at the junk yard. I knew that he just wasn't thinking it fully through. it would be pretty funny though. just one speed for forward. :roll: we weren't able to get to it, because of other things. but the weather is suppost to be nice again tomorrow (sunday) so once again we might work on it.

good news. I picked up the rear end from the junk yard and it's off of another mj. now I just hope that it has the right gearing. And hopefully I will be putting it in tomorrow night.

yeah then i'd have to do the front too. The big problem is that the truck is at a friends house right now and doing the front along with the rear would just take more time then I have. his girlfriend is getting pissed as is, that the thing is at their house. :roll:

man I am so angry :headpop: stupid jukyard didn't know what gears was on the cheokee that they were going to pull the rear end off of. so when they went to pull it they found out that they only had 3.55 gears!!! arg, oh well at least they found the right 3.07 gears at another yard and "should have them on monday or tuesday". good thing I'm on vacation and have another car to drive, an 04 hyundai tiburon. it just sucks driving that car in snow. oh well such is life. thanks for all the help and letting me vent about it.

So welding it is!! that's not to hard of a thing to do anyways. I have done some welding myself and I also have 2 friends that could do it. one will be helping me with the swap anyways so it will more than likely be him.

Thats what i had figured. I'll more than likely either weld or take it apart and put the new gears in the old rear end.

thanks for the tip. the guy at the junk yard said "just flip the axle around", i was like what? then he said yeah all the ppl that lower the chevy s10's flip the axle and put the leafs under the axle. i don't think it will work but we'll see tommorow when i get the axle. because of this crappy weather they didn't have any guys available to take the axle off today. but at least I scored some bucket seats from the same 89 xj.

(3.08, w/e) sorry, but what exacly does that mean? I must be having a stupid moment. thanks.

well I will be picking up a new/used rear end from the local junk yard. the guy at the desk says that it will be a 3.08. I really hope he is right. I had him pull that off another jeep. I think it's an old cherokee. I know that I should upgrade but, i need to get this thing running with the crappy weather we have been having in upper IL. the guy at the junk yard said that it would have the right gearing stamped on the front diff, has anyone else heard of that? if so then i should have just done that. I appreciate all the help and welcomes to the the club. thanks. mjeff87- thanks for the tip I guess i could still confirm it tommorow when i go over to my friends house to work on it. I just was hoping that i didn't have to rip the whole thing apart to find the right gear.

Thanks for the help!!! yeah it's the 35. now I just got to find new gears or a whole new rear end.

First I just wanted to say Hi :waving: . I just recently bought an 88 mj 4.0 5-speed long bed for $600. the thing was hit in the passenger rear but not to bad. only 80k on the clock and a blown rear end. now the problem i have is figureing out what gear ratio it has. I took the cover off and tried counting the ring & pinion. then my friend also tried counting it. he came up with a gearing of 2.85, now i know that isn't right. I'm thinking it's a 3.07. so the question is, is there any way to tell without taking the whole thing apart? or does anyone know what is the common rear end for the mj's with my setup? the onther issue i'm having is if it's a 44 or 35. any help will be greatly appreciated!!!!! thanks.
