tj front D44 into xj, why isnt this more common

hey all. not having an easy time seeing many of these installs, maybe 3 threads off google. ive been looking for a week and it might as well be a tall tale swap.

is there any reason why the tj rubi front d44 isnt a more popular swap into the XJ?

is it rare, is everyone modding xj wagon axles or similar....?

ideally if i could get one out of the yard. it would become a 4.56,trussed, and new uca brackets for LA.

is this a difficult axle to source from the yard?

really looking for any helpful insight, im not sure why it isnt more popular/ more info on this.

likely ide add a different locker.... really i would just want to build the tj d44 or see its potential when built up.

thanks for bearing with me guys, im not above research, but i must be missing something to not find better info on this.
further more does this axle have any axle spline upgrade options? i know knuckles are the same as d30.

another ? that popped into mind is what would be the value of shortening a jk 44 and clocking the Cs to an xjs angles vs a tj 44 build.

current set up is a 8.25 rear locked, hp30, 4.56. im looking to gain knowledge on swapping a stronger hp30 substitute.

your thoughts, wisdom, knowledge is appreciated, thank you.

Most likely the fact that they are a LP D44!

Its low pinion and the jk axle will require the same if not a little more work than swapping in full width or wagoneer axles.

wagoneer 44s are LP... people do those all the time. but i would put it as a close second. first and foremost, TJ stuff fetches a premium. basically, if it came out of or goes into a wrangler, expect it to be expensive. its also essentially a LP44 center section with D30 outers. all you are getting is a bigger ring gear.

now... the JK stuff is a completely different animal. unfortunately it doesnt adapt easily to 5on4.5 bolt pattern. your better bet is to also use a Jk rear axle. youll appreciate the little bit of extra width. itll let you use a properly back spaced wheel for scrub radius and help keep the tires off the control arms.

Re: tj front D44 into xj, why isnt this more common

Primarily its that they are uncommon and go for more money than they are worth. If I stumbled over one for $800 or less I'd drop it in my jeep before dinner tonight, but the few that come up go for top dollar, and they are barely better than a HP 30.

Re: tj front D44 into xj, why isnt this more common

They are kind of rare. Also not that good relative to other D44 options, the only [immediate] advantage over D30 is the larger ring and pinion and the built-in air locker.

I have TJ Rubi 44s in my XJ, but they were partly built when I bought them, and it saved me a lot of money over doing the initial work myself.

Ditto

I'm running a trussed one up front. Bought it with the brackets cut off, swapped 4.56's and an arb with a matching 8.8 for the rear at a price I couldn't pass up.

But For the price most people and yards want for them in my opinion there are better ways to go.

The day I see a rubi TJ in a junk yard is the day hell freezes over!

Not self service yards that's for sure

But the dismantlers seem to get them on occasion and want $1500

and they are 30-spline vs the 27-spline D30

but that also makes it harder to find spares

Re: tj front D44 into xj, why isnt this more common

I managed to snag a Rubi 44 off someone who ordered a Dynatrac, only real way you can seem to get one these days. Rubi locker and all. No way you'll find one in a yard. Have a build thread on here covering most of the swap.

The low pinion factor isn't really a deal breaker for me. 4.10s are a thick cut gear and the axle can get stuffed up nicely at compression. If you're in the racing business I guess thats a thing. But like everything else, opinions may vary.
