Question Ford 8.8 Swap On the Front Axle

So I've been doing a lot of reading and creeping around doing research and it I can't seem to find any information about swapping the front axle out with a Ford 8.8. I plan on going either 35x13.5r15 or 37x14.5r15 on an '01 Wrangler TJ.
Here is a thread listing junkyard front axle swap options

I've done a bit of searching using google but I haven't found anyone asking this question or an answer to it. I figured since I'd be fabbing the back brackets can't I just fab the front?

Is there a reason the 8.8 won't work in the front?

That's mostly because the 8.8 is a rear axle. If you wanna go budget look into a HP D30 from a 95+ XJ

The D44 is used on the front and back of the TJ Rubi's right? I think that is the source of my confusion... that along with not having a firm understanding of solid axles. Isn't the D44 a low pinion axle?

My only concern with this is I am gearing down to 4.88 and I've read a lot about the D30 being weaker when geared down that far.

I don't mean to steer the conversation away from Ford 8.8 axle up front with another discussion that may have possibly been discussed at length elsewhere, but, if you don't mind me asking, what is your experience with running a D30 on 35's geared down to 4.88, Owen_TJ? (not trying to call you out, only looking to learn since your sig mentions many things I will be doing to my jeep: 8.8, 4.88, etc)

You may also consider a HP D30 out of a Cherokee and load it up with Chromo shafts.

The front Dana 30 is fine with 4.88 or even 5.13 gearing for 35's. Replace its axle shafts with aftermarket alloy shafts when a locker is installed and it'll be fine. The front axle seldom sees more than about 50% of the stress the rear axle sees on a regular basis.

I say the simplest answer would be it will cost a crap ton more money to convert the 8.8 to a driver drop, steerable axle than it would to just invest in a hp d30 or upgrade to a d44.

I ran 35's on my d30 with chromoly shafts and 4.88 gears for 3 years...i just recently sold the rig in my sig (couple days ago, still sad lol) but yeah...as jerry mentioned, front sees barely half the stress the rear does

you'll be fine with 35's, d30, 4.88's, and shafts

If I can't find an HP D30 from a 96-99 XJ I'll go this route with a bit more confidence. Either way it's gonna have lockers front and rear. Thanks for the perspective on stress seen by front vs rear axle.

Thanks for the reply.

HAHA right on. I considered a LOT of wranglers in my long search (6 months) but I couldn't bring myself to consider a JK for my use.
