Jeep yj AXLE SWAP

I have an 87 yj and i want to do an axle swap in the front and rear. I planned on doing the typical ford 8.8 axle swap so i get the strength, cheapness, simplicity, and width that i want for a daily driver. but then I want to do a front axle swap so i can have locking manual hubs, and the only ones for the front i could find were dana 44s and they were full width. I wouldnt mind having full width axles but id like to keep the axles about stock width maybe an inch or two wider but not too much. I plan on doing mostly daily driving with 35's (worn down to 34s) with 4:10 gears maybe 4:56. Upgrading because i like to rock crawl.

There are some early D30's with selectable hubs, if I'm not mistaken. I have one sitting at my dad's shop...low pinion, passenger side drop I think. No idea what it came under factory as I acquired this one from a very ghetto built S-10 mud racer that was purchased for the built 4-bolt 350 in it.

I don't know if the width is the same as the 8.8...but you could narrow a D44 to use Early Bronco inner shafts (or run Early Bronco axles). Personally, that's what I would do on a dual purpose rig because it gains you the strength of a HP D44 over the D30/35 stuff of the same width, and gets you serviceable bearings/hubs and dialouts.

There are other options, I'm sure... But narrowed HP D44 gets my vote, assuming you have the time, money and skill to collaborate all the parts needed to match widths and lug patterns.

Jeep wagoneer d44s are the right width for YJs. Front is a straight bolt in. Rear is just moving the spring perches. The front is like 62"s wide. Rear is a bit narrower.

I'm doing a Dana 300 swap in my yj. If the waggy is a passenger drop would be sweet. But will the bolt patterns be the same on the wheels?

IIRC the waggy axles are a 6 lug. So no on the bolt pattern. And as said, drivers drop. Could flip the 300 pretty easy though.

Waggy Dana 44s are low pinion, and the U-joints are the same as the later Dana 30s. It's really not much of an upgrade, and could be a downgrade.

For 35s, I'd keep the Dana 30 and put in a set of chromoly shafts. Then the 8.8 rear will be perfect.

You would have to give up your locking hub desire.

Or go to a set of Chevy axles, with front Dana 44 with a passenger drop. And forget the 8.8 in the rear

Wagoneer front. Get some chromoly rear shafts from Dutchman motor sports that are 6 lug for 8.8(last time I got a set they were like $250). And weld the tubes to pumpkin on the rear they like to spin.

So you're just piggybacking on someone else's thread?

Waggy 44s could be had in passenger drop or drivers drop, depending on the year.

Bolt patterns be the same as what? There isn't a Dana 44 out there that has a 5 on 4.5" that your YJ came with other than certain years of Dodge, and they are garbage. If you think you can keep the wheels you have with a Dana 44 you are mistaken.

How much information is out there on the web on Dana 44 swaps? (that's a rhetorical question, the answer is a LOT, go look for it)

Im new here. Need a lil advice.

I'm new to posting but have followed this site for a while and seems like alot of folks on here care about their Jeeps. I currently own a 1996 Jeep Cherokee. Had it since it was new and love it. The engine just keep on going. But my problem is with my 1987 YJ. I got it from a friend for my son. Just before i got it, he put a lift and 32's on it, but it still has the original gears. So, naturally it creeps no faster than 50 or so down the freeway. I need a budget fix. My son's college and just the cost of living in California (cant wait to retire and get the hell out) is sucking my pockets dry. I have heard about D44 swaps from Rodeo's or Passports and the fronts from a Waggy. Right now it needs to get my son to school and work and when he's done and its mine again, the fun starts.
i know there will be some money involved, i just need a fix cheaper than having the YJ re-geared. Any suggestions or ideas are appreciated.

Cheap regear?

Find a 30/35 out of a 4cyl YJ, they'll have 4.11s

Personally, I wouldn't put any money at all into your rear Dana 35 - not even a regear.

The cheapest thing you could do would be to put 30" tires on it, so the engine is back in its power band. Might look funny with a 2" lift...

Also, what engine/transmission/gears do you currently have? 2.5L, I assume?

The engine is the other problem. But I can deal with it for now. Its a 4 banger with low miles. It'll get an upgrade when I get out of Cali. Trying to do it now is like running your head into a wall with California emission laws. it also has a manual 5 speed. Thanks for the advice..Appeciated.
