Hey everyone, I'm new to the Jeep world and I'm pretty sure you've seen this question before, so please forgive me. Which in your opinion is the better rear to swap into a YJ, a Ford 8.8 or a Isuzu D44? Any info, thoughts, concerns, comments, etc would be appreciated. Thanks everyone!

They're both nice solid axles. Aftermarket is bigger for the Dana 44 so you get more gear and locker and axle options but its 6 lug so that needs to be remedied. Big thing is plan ahead figure out what front axle you'll be running and match the rear up to it. I ended up going with the Isuzu 44 out back and a HP Ford D44 up front. I used GM parts for the conversion to 6 lug on the front axle to match the rear.

If you don't plan on swapping your front axle, go with the 8.8. Usually cheaper, more common, same bolt pattern, disc brakes, and a bit stronger. And you can get them in limited slip. Not sure if you can with the Isuzu D44.

There are limited slip Isuzu D44's out there. They came in 4.10, 4.30 & and if you look real hard you can find one out of a 4 cyl Rodeo with 4.56. Disc brakes are available.

I don't know much about the Isuzu D44. All I know is that the 8.8 is common, stronger, 5x4.5 bolt pattern, and many of them have disc brakes. That's why its such a common swap.

I did the Isuzu rear swap about 3months ago I love it I would recommend getting g the 4:10 gears or 4:56 gears as the 4:30's are a pain to find matching gears for the front.

I found a jeep j truck front Dana44 that I am regearing with disc brakes so I have disc's all around and I did not have to weld anything only minor issue was getting the flex hose for the brakes Isuzu used metric fittings and jeep used SAE BUT I found a local hydraulic shop that made it for me for a fair price Summit Racing I think sells them also.

Any questions feel free to ask also the Honda passport has the same rear end years to look for are 93-97.

This has been a hot topic before so you can search the forum and get more info than you want

Ive been told to stay away from Scout D44's because they are a weaker axle. The broncos axles are harder to find in my area. The main reason I was looking at the Waggy D44 is because I wanted to stay as much jeep parts as possible. But almost every jeep ive seen, even low to moderate build almost always had a different rear.
