Or turn the axle shaft and count the pinion rotations. If one axle shaft remains still, rotate the moving one twice. If both shafts move together, then go around just once. (and if the other axle shafts rotates in the opposite direction, you'll need to hold it still) If the pinion rotates 3 and a half times, it's 3.54. But if you're buying a used axle, it's always a good idea to pull the cover and inspect for damage. :thumbsup:

Finally got to see Taken. good flick. :thumbsup: They exhaust sound track they used for the XJ made it sound pretty good. :D vroom..vrooooommmm....

Yup. The ratios come from dividing the number of ring gear teeth by the number of pinion gear teeth. Because axles come in different sizes, there are different numbers of teeth in them. For example, the Dana 30 will have 41 teeth on the ring gear and 10 teeth on the pinion, giving a 4.10000 ratio. The Dana 44 on the other hand has 45 teeth on the ring gear and 11 teeth on the pinion, giving a ratio of 4.09090. the Ford 9": has 37 and 9, giving 4.11111 Round them off and you get 4.10 and 4.09 and 4.11.

Moved my michigan fleet to the other side of the parking lot. :D still had to push the 88, but I do have a new gas tank for it and will install it one of these days.

Not that hard to swap dashes with another MJ. :yes: might be harder to convince the yard owner that it's really that easy. :(

You're super-duper positive of this? I've heard it both ways and would like to know for sure. :(

KKs have a 5 on 5" pattern. I think some KJs had 17" available.

~113" :thumbsup:

i hear people say that to, simply not true in my personal usage. i get way better gas mileage in economy mode. rpm's kill gas mileage, bottom line. Not necessarily. Fast acceleration kills mpgs. 80 mph kills mpgs. rpms are generally associated with these 2 circumstances, but are not the bad guys unto themselves. ok, but if 80 mph was only at 2,000 rpm it would not be bad. and when in economy mode, the same 3/4 throttle acceleration will shift sooner at less rpm. :typing: But if you need to really accelerate to get into traffic, using econo-mode will use more fuel because the engine is struggling to keep up. mpgs become more about the driver and the situation at hand, and less about the Jeep. There's no reason power mode can't get the same mpgs as grandma-mode. grandma-mode just forces you to drive like, well, like grandma.

you definitely want to reuse the old flywheel, since the CPS notches are specific to the older electronics. I reused my old Peugeot clutch with no issues when I swapped in my 99 AX-15. I used a 74 CJ bushing (with the 304 and manual trans) with no modifications (late 70s CJ stuff may be a bit different). You'll want to grab an AX-15 crossmember and trans mount. And there's some other stuff. no that the search is running properly, you should be able to find the older threads about the swap. :thumbsup:

That might end up being a crazy headache. Putting the TJ trans in an MJ is one thing, I'm not sure if it's entirely wise to try and go the other way. :dunno: probably better to hunt down a TJ AX-15, or try to fix the broken trans (depends on what exactly went wrong).

Because some of us have not always been into 4wheelin and can vouch that better gearing is still a good idea, even for a completely street-driven 2wd grocery-getter. :D You're going to be in for a bit of a surprise if you swap a 3.07 geared rear axle in and your truck gets slower. :(

Directions alone won't help much. you need a photo program that can do it (and do it well). :thumbsup: I use ACDSee and it's as simple as telling it how many pixels high. You can email it to me too. I can resize it and upload it for ya. :D ComancheClub@hotmail.com

Nothing horribly wrong with the adapter U-joints. I ran 2 of 'em for years (adapting to the ford axles under my 88). :thumbsup:

Why not just use the factory wiring? the starter already has a relay and fuse. you just need to run your cab switch to it (pulling power from an existing fuse in the box).

Is your factory starter relay and wiring intact? What was the reason for wanting the new stuff?

I don't understand the question. You'll still need a flange adapter. either the bigger Explorer on or the smaller Jeep one. The cop crown vic driveshaft idea sounds intriguing. IIRC, the crown vic uses the correct Jeep u-joint size on their version of the 8.8 and if everything works out right, you just need to grab a couple of cop crown vic driveshafts and have them shortened together (and get the proper 8.8 flange adapter at the same time). car-part.com shows a gazillion of the things available across the country.

Yup, not much harder. and then you won't have a gazillion amps running through the cab. Essentially you just need to run the big power wire from the battery to the starter, with the relay in the middle. Then the momentary switch in the cab energizes the relay. A factory relay works just fine for this. Don't forget the fuse! And then you won't need such a huge starter button. A momentary toggle switch will suffice. :thumbsup:

I suggest using a relay rather than running the power directly through a switch.

car-part.com may help you find a junkyard axle. Also check your local craigslist.org Don't fear using an XJ rearend, as welding on new perches is a relatively simple task that can be done at any muffler shop. :thumbsup:

If you didn't replace the U-joints when you did the lift, that might be a good place to start. U-joints don't like changes in their operating angles.

Your old man is right. You're really not gaining any clearance by cutting higher than the bottom of the bumper. You need a slider so that any contact is simply shrugged off. Plus too much trimming just looks funny imho. :dunno: admittedly my rear bumper sits up higher than stock so take that into account. I trimmed mine with the intention of 2 more inches of 2x4 underneath of it.

Never ever fix a Dana 35. Not worth the money (plus it's likely bent). Take this opportunity to upgrade and get a pair of XJ axles that have 3.55 or better gears in them. :thumbsup: Try to avoid another Dana 35 if you can.

Just as long as you don't call it "reverse rotation". :rotfl2:
