JEEP_cannible Posted April 3, 2019 Share Posted April 3, 2019 I have a WJ I bought for parts its a 1999. I already found out I can't really use the trans as I planned.Even if I could get in working in my 1988 MJ it probably wouldn't last long.So I have other question.Can I use the axles in my 1988 MJ or my 87 XJ would this be worth the trouble.I would really like to have rear disk brakes,and the newer axles. Mine arn't getting any younger. I have seen a lot of brake upgrades were they use the disks off a WJ. Thanks for any help here. I know the 4.0 can be done I just have to use a lot of the renix parts off my old motor. There is a really great write up in here about that swap.I also saw one on using the XJ axles in an MJ,but nothing about the WJ. Is there a problem with these axle's are they weak?Can't hold up with big tires,and lifts? I'd love some feed back on the topic.Thanks Link to comment Share on other sites More sharing options...
Eagle Posted April 3, 2019 Share Posted April 3, 2019 I don't know what the 6-cylinder WJ used for a rear axle. If it's the aluminum "Dana 44," it's not even a good boat anchor. There's a thread here not more than a week or two ago about the WJ front axle. Bottom line -- it won't fit without a lot of work, and even then the wheel lug bolt circle is wrong.

JEEP_cannible Posted April 3, 2019 Author Share Posted April 3, 2019 Thanks Eagle now I'll have to give it a good look.LMFOA I used to call my 79 wagoneer,(the boat anchor) she was one heavy Jeep. Link to comment Share on other sites More sharing options...
dasbulliwagen Posted April 3, 2019 Share Posted April 3, 2019 The 4.0 from the WJ won't even bolt into your MJ, the mounting points on the block are different. Theres almost nothing from a WJ that will swap to the MJ. Link to comment Share on other sites More sharing options...

I have a good motor,trans,and both rearends. Link to comment Share on other sites More sharing options...
Pete M Posted April 4, 2019 Share Posted April 4, 2019 YJs are wranglers. ZJs are grands from 93-98. WJs are grands from 99-04 a pic of the Jeep would answer any doubt. Link to comment Share on other sites More sharing options...
JEEP_cannible Posted April 4, 2019 Author Share Posted April 4, 2019 That's the funny thing Pete it looks exactly like my 97 grand that's why I bought it for parts. Tail lights,bumpers down to the same rim's. Only difference is one is the V8,and the other is the 4.0. I'll get this right sooner or later ZJ Pete its a ZJ.

JEEP_cannible Posted April 4, 2019 Author Share Posted April 4, 2019 I'm thinking it's a ZJ,and not a WJ.I even checked the motor mounts,and the look like my XJ only smaller.They were also in the same location.You can't really see the bolt pattern very well.So not for sure on that one.What about the axles anyone know if its worth a swap,or just use the rear disk brakes? The conversion didn't look that hard,but some newer axle's would be nice. Link to comment Share on other sites More sharing options...
Pete M Posted April 4, 2019 Share Posted April 4, 2019 "newer" you'll be trading in 30 year old parts for 20 year old parts + a ton of work. BUT if you get a bump in gear ratio, then it might be worth it. ZJ front axle should go right in (but is low pinion). Link to comment Share on other sites More sharing options...
JEEP_cannible Posted April 4, 2019 Author Share Posted April 4, 2019 Yeah your right,but the 20 year old parts have a ton less miles on them 30, verses over a 100, I'm not feeling the,( low pinion) though.Maybe better to just use the disk brakes less work. I think the trans is a no go too.What you think about the 4.0 usable or not ? Link to comment Share on other sites More sharing options...
Pete M Posted April 4, 2019 Share Posted April 4, 2019 I think the ZJ 4.0 is swap-able with MJ/XJs. Don't start undoing bolts until someone confirms that though Link to comment Share on other sites More sharing options...
Limeyjeeper Posted April 4, 2019 Share Posted April 4, 2019 All 4.0 blocks having the same engine mount.points. Completely interchangeable. They didn't cast different blocks for different applications. A bit like the LS blocks. Edit. To clarify - However the 2001-2006 TJ blocks and 1999 to 2004 WJ blocks did have blocked off mounting points that would need to be tapped along with a water pump hole. There are some other differences that make a swap difficult but not impossible. All the ZJ and XJ blocks were all interchangeable..

dasbulliwagen Posted April 4, 2019 Share Posted April 4, 2019 WJ and Late TJ 4.0 had the mounts in a different location. The points may be on the block, but won't be machined or threaded. Link to comment Share on other sites More sharing options...

Well, the WJ was a completely different vehicle, so if it looks like a '97 ZJ, then it's a ZJ. Post a photo so we can see it. The ZJ was more or less a derivative/evolution of the XJ. In fact, I've read that the ZJ was originally intended as the replacement for the XJ, but the XJ was selling so well that Jeep decided to keep it and introduce the ZJ as a separate vehicle. The WJ was to be the replacement for the ZJ, but Chrysler-Jeep went out of their way to make it completely different. I think I remember the early WJ ads making a point of how few parts on the WJ were carried over from the ZJ. From the build date, it sounds like what you have is a '98 ZJ, not a '99 WJ. What's the VIN? That should tell us the actual year and model. If it's a ZJ, the 4.0L should go into an MJ but the electronics, fuel injection, and accessory mounting points will be different. The fact that the ZJ front axle is a low pinion is really only a factor if you plan on serious off-road use. (Jeep changed to a low-pinion front axle in the XJ in 2000.) For the rear axle, I know the V8 ZJs used the crappy aluminum "Dana 44." I don't know what rear axle the 6-cylinder ZJs had -- if you post a good photo of the rear axle, we can probably tell you what it is. Link to comment Share on other sites More sharing options...
FrankTheDog Posted April 5, 2019 Share Posted April 5, 2019 4.0 ZJ’s will have a LP30 and a disc brake D35 in the rear. Even the early V8 ZJ’s had the 35. The front brakes will be identical to any 90-98 XJ. Engine is the same as 96-98 XJ’s and TJ’s TJ’s were made from 1/96-6/98 with XJ compatible engines except for the accessory mounts. Transmission is trash. Link to comment Share on other sites More sharing options...
gogmorgo Posted April 5, 2019 Share Posted April 5, 2019 4/98 is early enough in '98 it's unlikely to be a '99 model year, even on a new generation. It could easily be an error on the title, although I'm surprised that it could slip in like that. Digit 10 of the VIN is the model year regardless of make or model, and almost any system should be able to pick that up. '98 is W, '99 is X.

I don't know what rear axle the 6-cylinder ZJs had On intitial rollout every ZJ had a Turdy5, including the V8s. It was a couple years in before they offered the 44A. I think there were a couple packages where the 44A was also offered with a 4.0, but the base axle was the d35. Link to comment Share on other sites More sharing options...
JEEP_cannible Posted April 5, 2019 Author Share Posted April 5, 2019 Thanks you guys for all the help. I've been trying to download pictures off my phone to my PC for a couple of days.I think I may be using the wrong cord.Going to try again in the morning.Its been a while since I was under that ZJ ,but if I remember the dif cover looks just like my XJ.My MJ has a different cover same shape rubber plug.I learned a long time ago in auto body school that the titles are not always 100 %. correct on the year it was made.Some states go by the year it was sold.I learned it again the hard way.John my body shop teacher would be ROFLHAO at me right now. Always check the door plate,or the tail lights unless they've been replaced they almost never lie. That sucks for me the drivers door on my MJ has been replaced.So i don't really have any build specks for my truck.The guy I bought the truck from said it was really rare 4WD,5sp,with the 4.0.That there was only 500 built like it that year.Sounds like BS to sell the truck now.I already knew that the MJ's were rare anyway,and I really liked the trucks potential.I'll get some pictures up of the truck as soon as I can. WOOHO Axles I can use,and motor check.Trans some junk to sell. Thats a great end for a bad day. Thanks again to all of you. Link to comment Share on other sites More sharing options...

JEEP_cannible Posted April 5, 2019 Author Share Posted April 5, 2019 Wow just from one number Wagon that's some cool stuff. Its now black,and not the green,and rolled a little the only straight panel left is the rear hatch.What the heck dose 175 mm rear axle mean? I see it has a dana 30 front,and 3.55 gears.I found the codes for the trans,and t case.as expected junk for what I wanted to do with it.I'm thinking someone swaped the the T case shifter plate.After being under it yesterday I don;t think its been swapped out.No marred bolts,no gouges in the under coating.I'm thinking its the stock T case.Thanks for the help Wagon.

dasbulliwagen Posted April 5, 2019 Share Posted April 5, 2019 175mm is the size of the ring gear diameter. Most likely a dana 35 Link to comment Share on other sites More sharing options...
dasbulliwagen Posted April 5, 2019 Share Posted April 5, 2019 I did some more research on the 175mm. It may be that the build code has been recycled for something else. The service info doesnt show a 175mm axle option, that and the Dana 30 is 186mm, so that code probably applies to something else now, and not the ZJ any longer. A lot of the MJ codes have been recycled the same way if you get a look at a build sheet. here's your Comanche...

JEEP_cannible Posted April 5, 2019 Author Share Posted April 5, 2019 That"s good news then.Some parts I could use,and some I can sell.Any one need a trans or T case for there 4.0 ZJ. I'll move a couple of Jeeps around on monday.I'm thinking its about time to part out some of whats left of this thing.Thanks again for the help.I'm never going to get used to seeing MM on American cars.
