Ok I have decided that I will be shopping for a ford 8.8 for my YJ this weekend. I would like to know if there are any differences in an 8.8 out of a V6 exlporer or a V8 explorer? Do they all have 31 spline shafts after 96 as long as its out of an explorer? I am looking for 4.10's and the V6 8.8's are a lot easier and cheaper to come by so far. I searched and didn't find anything.
Go to a Ford dealer and ask about it in general, and ask about part numbers for rear shafts for various models. Since I wouldn't intend to buy anything and it could take a while of his/her looking, I'd go there face to face rather than just call.
All Explorers got the 31 spline shafts, doesn't matter which motor it got, or what year. Starting in 98 they started using bigger wheel bearings, I believe 98 was also the first year of the 7/8" crossshaft in the carrier, instead of the 3/4".

'95-'01 Explorer's had disc brakes, so look for them. '02 and later had a change to IRS, so they don't even have a solid rear axle. I found my axle off of craigslist. I put out a wanted add and got a couple of offers within a couple of days. I ended up with an '01 having factory 4.10's for $50. It's another option to try.
The application for the axle should determine the carrier you eventually use. The Limited Slip found in the 8.8 is known to be a bit on the weak side for heavy abuse, where the open carrier is more stout in design. If you want to keep the limited slip, you can buy a high performance rebuild kit for it which stiffens up the action and supposedly keeps it from wearing out as quickly as normal. I think the rebuild kits are $30 or $40 dollars. If you have the choice between an open carrier and LSD on the axle you buy, you might want to pick up the LSD, even if you do not want to run it. Alot of the FORD racing guys like these and will pay upwards of $150 for the LSD carrier while an open carrier is much cheaper to replace it with.
Yep, it doesnt matter as long as it is a 95 or newer. Mine came from a 96 2wd exploder with the V6. It has 3.73's and the limited slip.

make sure that you know what an 8.8 looks like. im not 100% sure, but i know i read somewhere that an explorer came with a dana 35... maybe a base modle, i could be wrong, but in my research i remeber reading that. anyway just make sure you know what it looks like. go to the U Pull it yards they only look at the lugs on it. the whole axle cost me 50 bux. that was disk to disk. check out the gear oil in the yard see what you are buying before you get it.
