Cherokee - Mj compatibility??

[Bonkers]

Here's the scenario. I came across a relatively cheap 90 Xj this morning. All I want out of it is the Ax15 swap, but for the asking price that's way too much. However while looking it over I'm wondering what other parts I can use. I can't tell if the motor is renix or not, but it sure looks it. The power windows would be a nice touch if they can be waterproofed. I know the seats and driveshafts are both throwaways. I can make $50 on the dash cluster.

 

My Mj is a 89 Pioneer.

 

Let me know opinions quick.

90 is still Renix, I always look at the throttlebody to confirm because it's distinctly different. The front driveshaft isn't a throw-away.

You may need the 23 spline t-case too.

[rejeep]

They are the same jeeps, minus a bed.

you will deff need the case of swapping for a ba10.

4-door? the whole doors are the same

spare axleshafts n such, sensors, electric fan

[whowey]

Front doors, and everything from the top of the A-pillar to the front bumper are the same. The main exception is the body harness.

 

But like they said, the front D-shaft and T-case if you are doing the AX-15 swap.

I'd go for a newer external slave cylinder AX15 instead of that 1990 one.

I'd go for a newer external slave cylinder AX15 instead of that 1990 one.

good luck with that, they fetch quite a premium.

I could go and buy a 4WD AX-15 with BH for $300, but if I want the later model external slave one the price goes to $500.

There's nothing wrong with an internal slave, until something goes wrong. And even then it's only a huge problem if dropping the trans is a huge problem. To some people out there, it isn't that big a deal. I'm sorta in the middle on that one. It's a pain, but I can do it.

I bought an external slave bellhousing for my truck ONLY because I found one cheap AND because the internal slave was already toast AND because all the parts came with the external bellhousing. So as long as all the used parts are good, I fixed my bad internal slave for like $35. The big reason the External slave transmissions are more money is simply because they are newer and tend to be lower mileage.

i have heard somewhere that mjs and xjs are the same firewall forward!?

 

not sure if its 100% but some things are for sure

[Pete M]

Pretty much, yes. There are some things that XJs had that MJs didn't (like a washer bottle with a second pump for the rear window).
