what is your tire planned tire size that has much to do with what you should replace it with. Me personally, I am going with a Super 35 since I don't plan on going bigger than 35" tires.

A Ford 8.8 is the best choice overall for an upgrade. Super 35's are expensive and IMO still not as strong as a 8.8. You should be able to pick one up for 200-300 bucks at a salvage yard

^ agree. Unless you don't want to swap housings.

I say run it til it blows. If your not running big tires it might last for a while. Maybe. LOL!

Are you a capable welder? or know one? If so, another vote for the 8.8. Since you will be doing the swap on a YJ, the work will be easier on your own than it is on a TJ (way less brackets to weld and mock up.)

First question....can you weld or do you know someone who can?

97-02 should be a disc brake one if you want that, earlier ones will have drums.

I have a writeup on here about doing a spring over for my dad and I show how to make the e-brake cables work without buying a thing.

Here is a ton of info i found on the 8.8 that I compiled in a thread for reference purposes. It will tell you all about the axle as far as years, vehicles its found in, etc.

I believe the older ones also had a lower spline count.

Ya I am pretty sure the years that had drum brakes ran 28 spline axle shafts compared to the newer disc brake axles that run 31 spline shafts. In the thread I linked, I think that is listed in there as well

One of these days youll run real axles...dana 60 fronts...what a joke

I don't know I'd it was said, all I saw were the years, get the 8.8 from the explorer, the disc brakes are the 31 spline. The ranger and mustangs are 28 spline if I remember right.

I have a super 35 kit in mine with a Detroit. I got most of it for free when my father in law went to a rock jock 60. It originally had a lock right in it. Those can be temperamental. You have to hog out the ears on the stock case to accept the larger axle shafts. That is now your weak point. We thought we killed his ring and pinion originally with that super 35. When I tore it down I noticed the ears where the bearings are pressed on broke right at the case. So his whole case was flopping around. I replaced it with a Detroit and the shafts he was using. With my 2.5 and 35"s, I'm not worried about it. A full locker is the only way to go with a super 35 kit.

Actually 95-00 Explorers were 31 spline with disc rear brakes. 94 back were drum brakes. Guns-R-Us, question for you, where is Atlanta TX? I am up here in the panhandle of Texas. Lubbock that is. 120 miles due south of Amarillo.

I've said the same thing about the 2.5L, and I'll say the same thing about the D35c.

You can dress a real ugly girl up with all new cloths and make up all you want, but at the end of the day she's still a real ugly girl. I think some people keep their beer goggles on to long
