Default 8-lug Dana 44 custom build questions/options...need input

I just picked up either a 2007-2008 JK Rubicon Dana 44 front axle housing (just the housing, gears & e-locker). The donor vehicle was in a collision, and the short side tube looks a little tweaked. It'll be a custom axle, so I wasn't overly worried about it given the minimal investment.

I want to eventually install this in my '05 LJ, and it'll be matched with a Dana 70U CJ-10a rear axle that I'm going to have narrowed, and convert to disc brakes (GM brake parts). I already have a set of H2 wheels to run on the Jeep.

I'll be getting some quotes to get the JK D44 front axle re-tubed, and the plan is to add "old-school" (non-TJ/JK) Dana 44 inner Cs. The JK 44 tubes have a 2.5" OD, while the old 8-lug Fords are 3.0", and FSJs are 2.75" (I believe)...I haven't looked into GM D44 info yet. My thought is to go with 3" replacement tubes, which will have to be machined down to 2.5" where they press into the housing, and have the tubes welded to the housing similar to what's done with the Poly Performance/Synergy HD Retube Kit. The 3" tubes could then accept Ford inner Cs, or aftermarket ones like ones from Parts Mike. I'm looking to maintain a 65"-ish width.

I guess I'm looking for any input regarding flaws in this plan, and/or suggestions as to what manufacturer I should utilize for knuckles/brakes. I'm guessing that I'll have to swap to a Dodge truck master cylinder after going with heavier-duty brakes, as well. This Jeep will only have a 2-3" of lift and 37" tires (high-lining), so I don't see a need for hi-steer.

Suggestions? Feedback?

Thanks,
Craig

It sounds good, but I'm a visual kind of guy. I'm sure that you'll post some pics here shortly, so I'll save feedback until then.

I've been doing a lot of research on the bigger brakes vs what M/C to use. Lately the general concencus on Pirate is a 2000 WJ M/C and booster combo.

I hope that helps!

You can also look into CJ dana 30 inner C's. Those are 2.5" tube and will accept a ford D44 knuckle iirc.

I guess I'd say does it really benefit you that much just for the JK ring and pinion. I know its stronger, but do you think a regular HP44 would work.

Because a F250 (or retubed F150) HP44 front is already drivers drop, 8 lug outer, and about the right width. The F150/Bronco fronts are 65" wide, not sure if the F250 is a little wider.

Lot of work to get that bigger pinion gear.

Thanks Tim. I'll do some searches on the WJ M/C.

Thanks. Yes, I knew about the CJ D30 compatibility, but I'll likely be going thicker.

Haggar - It was a combination of the reasonable price ($280), the stronger R&P size, AND (big bonus) the included electric locker. Yes, an older D44 would absolutely work (as would several other options), but with the 8-lug stuff, it's still a little wide for what I want; the width would be wider than 65" with 8-lug outers. In fact, someone here on the board has a built, late '70s Ford D44 that's already geared with 4.88s for a very reasonable price, but I don't have the $$$ to do it all up-front.

I also don't have the cash to do it all at once, so I can save & build as I go.

Any other input regarding which 8-lug outer parts would be the best to use?

Ford? Chevy? Jeep?

I would Say Chevy parts,

I like Chevy Calipers vs Ford Calipers
Chevy brake parts are EVERYWHERE and cheap
Also I think the Chevy Hub assemblies etc are more plentiful

I have built 2 HP fronts for my Scouts and have the 78-79 Ford diffs with GM 8-lug knuckles out. With some carefull planning, both were put together with Scout widths between the knuckles. With the GM outers, HF ended up at 63". It was alot of work, but I did it all myself and in switching the diff to the right side, I sleeved over the splice in the axle tube. I have beat it and it is still together. I can take some pics and send if you want, just for ideas???

Thanks gentlemen. I definitely appreciate the input. For the GM parts, I'll do some searching to figure out which years are best to use. Thanks again.

mehoffine - Yes, if you have in-process pics from your build, I'd love to see them.

I disagree, Josh. I have already gotten quotes, and have done a substantial amount of homework on the subject. That being said, I'm not talking about a "junkyard D60" install; I wouldn't install a high-mileage D60 in my Jeep without a thorough rebuild (unless it had proven low mileage).

I definitely appreciate the input. Keep in mind, though, that I'll be running 37" tires max, and also do not have a tow rig/trailer. I'd be driving to trails. It'd be a different story if it was a trailer queen, without a doubt.

Regarding having worries, there's quite a bit of feedback on Pirate about guys running 40s on beefed-up JK (new generation) Dana 44s without issues.

I did a lot of research a few years back when i was building my axles.
Do to availability, and casting beefiness most of my parts are mid to late 70's. I believe things like Calipers are interchangeable up to late 80's? and such, but don't take that verbatim.

I did end up with a mid 70's hub that uses external style lockouts.
While I haven't had any issues running milemarker premium's (carry drive flanges in the toolbox) some people do prefer the internal style. I have been happy with this setup.
