Why do I like mine? It's rare, it's strong, it bolts right in. :D It is the same width as any other MJ rear axle.

Send me a PM with your address and I'll mail some out to you. :thumbsup:

I would call the manufacturer on that one. They would know for sure. :thumbsup: My guess is POR goes on first since you need it against the steel to be effective.

I would get the 3.55 Dana 44 and never look back. Then I'd locate a matching front axle (they are everywhere since it was the most common ratio in XJs). Jeep should have never used the 3.08 ratio. I got better mileage once I swapped to 3.55s in my 88. :cheers:

Actually, I do believe the '86 2.5 was rated higher in HP, but still a hair lower in TQ than the 2.8. :D I can't seem to find all the numbers though. :hmm: Where did I see them...

Check with advancedadapters.com I know they were working on an AX-15 kit, maybe they have a 3550 kit too. :dunno:

If someone wanted to compile a list of the general changes over the years (don't get too carried away), we could put that in the DIY forum. Problem is that there is still some disagreement amongst the members about things like the np-242, available gear ratios, parts used during change-over years, etc. Very few rules are written in stone because of the ease of interchangeability and that the "rule book" seemed to be thrown out the window back in the day at the factory. :shake:

As Jeepco said, the "41 11" are the important number there. 41 is the number of teeth on the ring gear, 11 is the number on the pinion. 41/11=3.73 Something in the back of my head says TJ 44 have different gears, but I could be thinking of ZJ 44s (with the aluminum housings). Best to find someone to confirm that.

My 86 has 4+1. :D

Exactly, rather than old diesels where the fuel injection was completely mechanical in nature(from timing and duration, all controlled mechanically via the IP(injection pump)), which had equal length lines running to each cylinder to an injector nozzle, this system uses electric injectors just like MPFI gassers, with a high pressure common rail feeding all the injectors(like 23,000psi high pressure). The next generation of 2.8L VM engine uses piezoelectric injectors and even higher pressures, something on the order of 36,000psi or so(currently sold in the KK overseas) More like Italian :fool: I was thinking more along the lines that Jeep was German-owned at the time. :D

The TJ/00XJ/01XJ axle will work fine for up to maybe 3" of lift. Beyond that I'd look for something high-pinion. If the XJ/MJ had a 4.0L, the axles will likely have 3.08 or 3.55 gears. If it's the 2.8L v6, then there's a chance it'll have 4.10s. Yes similar drivetrains will swap directly between longbeds and shortbeds (except the rear driveshaft). The 2.5L/5-speed XJ will likely have 4.10s. :thumbsup:

That list would be huuuuuuge if it were complete. Occasionally they changed the colors of the wires, apparently just for the heck of it. :dunno:

I'd start by making sure water can't get into your cab from the windshield. :eek: And as the old saying goes, "no guts, no glory". :D Water in the fuse box should have long ago evaporated. (wouldn't rain also be getting in there if it's that easy?) I'd start with the simple things and work my way towards the hard. This could all just be mere coincidence and you could be tearing apart the fusebox for nothing. :thumbsup:

With all the swap-ability of parts on our trucks, there's no guarantee that any particular 22 year old MJ with an Amc-20 will have the metric leafs still attached. But if we're talking about "from the factory", I've found no evidence yet that the '20 was ever offered outside of the big ton package. But then, all sorts of weird stuff happened back in the day. It's almost as if we have to put an asterisk next to any statement about MJs. :(

It stands for "Awesome Jeep Engine". :thumbsup: Though I'm not sure why the letters don't match up. :dunno: Maybe it's in German? :D

The 2.8 is an inferior power plant.

I would start with checking the condition (and then clean) all the harness grounds, light sockets and the wires that run to said light sockets. :thumbsup: It can be a slow process to bring an old girl back to life, but be methodical and you'll get there. :cheers:

The car just needs a new fender. Big deal. The MJ now needs some serious TLC. :(

If you were stealing parts from an 84-85 Cherokee, would they be even older? :hmm: I can't say for sure, but I doubt much of the wiring/parts in a 2.5L truck changed from 86 to 90. The repair manual should be very useful. :thumbsup: As to the parking lights, many owners have had issues with the bulb sockets corroding.

I would remove the inspection plate and check the condition of the teeth on the flywheel. :thumbsup:

You'll need an entire 4.0 XJ. A complete donor rig comes highly recommended by those who have elected to take on a similar swap. Your t-case won't bolt to an AX-15, so add that to the list. Find out what ratio you have in the axles and let us know. :thumbsup: Did you swap the Dana 44 in?

What axles and gear ratio are you planning to use?

Is it for your TJ?

Far as I can tell, the torquefite has a good rep. A bit of an old design though, and it doesn't have overdrive. The big problem is that the 2.5L doesn't do well when mated to any auto. There's just not a lot of power and the auto sucks more of it away. There are kits out there for mating an AX-15 to the 2.5L if you're concerned about strength. What size tires are you running? Do you know the gear ratio?

How far are you hauling that amount of wood? How fast would you be traveling? Are we talking coming out of the woods? Or running down the roads?
