If it's out of a 97 it will have disk brakes and any of three standard gear ratios - either 3.55, 3.73, or 4.10. The swap is pretty straightforward.. I'm actually in the process myself - just got back inside the house from painting the axle. You'll have to move spring perches and you can usually find spring plates with shock mounts on them... If you're handy you can modify your ebrake line to work. My best suggestion is to google the 8.8 swap.. It will show some great write ups.

We did the same thing for my 93' YJ. My gears are 3.73's. I don't know if you'll have this problem, but I had to fabricate a shock mount. Total time to do the swap from start to finish was about four hours.

I was able to find spring plates with the shock mounts built in... I wonder what model they came off of... Cause the swap was so easy with those. No extra welding.. I'll try to find out where I got them from.. Cant remember right now

You'll need the flange adapter thingy from an earlier Explorer model.The disc models are the next size up U-Joint.Some people get a conversion joint but its easier to get the earlier adapter and then the U-Joint is stock. I use the explorer spring plates w/shock mount.

Also if you have a 6cyl model you can use a 4cyl driveshaft as the 8.8 pinion is closer to the tcase then the stock axle.This works without a SYE and up to about 3" of lift

Sounds simple enough!
What front axle would be equal to the 8.8 that i could throw 4.88s in?

My plan is to eventually go with a reverse cut Dana 44... But to each his own

When swapping from the D35 to the 8.8 the pinion is offset a bit over 2 inches.
Does this offset create any vibration issues?

You didnt have to relocate anything for you shocks to work? I thought the factory explorer spring plates would sit to low to work. are you SOA or SUA?
