I know the 8.8 is nearly a direct fit for the 95 yj 4.0 dana 35, but am not sure if I should re-gear now before the swap (some time in the not so near future) or wait to re-gear until after the swap because the dana 35 gear set may or may not fit into the 8.8 housing . . .
To answer your question, Yes. You would have to purchase different gears when you swap into your 8.8. The 8.8 is a compleetly different rear end. It is almost a direct swap in that the width is almost the same, and the lug patern matches the 5 on 4.5 lugs. Other than that, it is compleetly different. Different axles, Different Ring Gear/Pinion, Different carrier.
Now as to should you re gear now or wait. That depends on how long before you go with your 8.8. If it is going to be a year or two then go ahead and do the gear swap. Just know if you go with a larger tire (35's) you may have trouble with that D35 rear. It is just not built for that larg of a tire. Especially if you lock the rear.
If you are just changing gears, the ring gear and pinion will run you about 150 or 160 bucks, and you will most likely need a new carrier that is for 4.10 gears and numerically higher. That will cost you another 90 bucks or so. THen unless you know how to set one up, you will have to pay a shop to do the swap. This can cost you anywhere fron 150 to 250 bucks. Depending on the shop.
Now if you are looking to do a super 35 kit with axles, locker, gears, the entire thing. I would say wait for the 8.8.
Another thought is if you want to go 4.56 now with your D35 rear, I can hook you up. I have a 4.56 ring gear and pinion and carrier sitting in a box in my shop I took out of my old rear end when I swaped to my 8.8. THe ring gear would need to be taken to a machine shop and have a bolt that broke off removed, but other than that, they are not hurt. If you are interested, hit me up with a PM. We will talk before I put them on Ebay.
