Cj7 Dana 30 6 lug conversion

Hey y'all. I have an 85 CJ7 that I bought as a project. For various reasons I'm contemplating converting the Dana 30 to 6 lug. From what I have found Chevy Dana 44 knuckles and outer components will switch over. Most of the walk throughs I've found cover this conversion on YJ's, TJ's and newer 30's. The possibility of high steer seems to be the driving force in most of these conversion but in my case I'm really after the 6 lug Chevy hub. I have found some very vague discussions on earlier 30 conversions, but they kept 5 lug pattern using the stock CJ or Ford parts. Some of the information I've found says I'd need the outer stub shaft from the 44, others say it's not needed. Others say that a new inner shaft would be needed as well but that was with the later year 30's and their different C's. What I would really like to know is can I just take the 44's knuckle, stub shaft, spindle, hub and all the brake components and swap them over to the 30 without changing the inner shaft? Or can I get away with just running the Chevy stuff on the 30's outer stub shaft? Any help and guidance would be greatly appreciated. Thanks

Does the D30 and D44 use the same axle joint?

From what I've read a lot of the components of the D30 and D44 are the same. And that the axle joints will match up but I guess the D44 has a stronger u joints. But like I said most of the information I've found deal with doing the swap on later model D30's. Apparently the C's are different than the earlier D30 and D44. So they require swapping in earlier CJ D30 C's and the D44 knuckle and outer shaft.

Why don't you just stick a 44 under it?

Because I don't want to run full size axles, out board the springs or cut the long side down.

Buy a chevy 10 bolt for $100. Swap everything from the knuckle out. Voila

You dont need high steer on a spring under CJ d30.

So I should be able to use the D30's knuckle and outer shaft and just use the 10 bolt's spindle, hub, calipers and rotor?

Don't know about that but if width is a issue a front 44 out of a '03 to '06 Rubicon TJ will bolt in.

The knuckle, stub shaft, brakes and what not from the 30 will fit, It's still Dana 30 though.

But that won't get me the 6 lug pattern that I'm needing

What I'm trying to do is convert a D30 in a 85 CJ7 to six lug to match an Isuzu D44 that I'm planning on installing because the the AMC 20 is bent and was cannibalized before I bought it
If I can find rotors that are 5 on 5.5 and will work with the parking brake on the Isuzu, I'd being willing to send the 44's shafts off to Moser to get redrilled

Sounds like pain.

If I was you, 44's out of a '03 to '06 Tj Rubicon would come to mind.

What size tire are you planning on running?

This sounds like a noob thread.... Hardly hardcore, pirate is certainly becoming soft.
Dana 44's can be had in Wagoner widths, wider than a CJ but hardly full size

Rubicon 44's aren't in my budget at the moment. And it currently has some 35x12.50x15's. They're a bit old but stil have plenty of meat on them. Will probably run them till they wear out then will probably stick with 35's or drop to 33's

Hey stupid, shut the fuck up if you don’t know what you’re talking about. For him to switch to a Rubicon axle he needs to switch his transfer case possibly move his exhaust and a bunch other bullshit that isn’t necessary for what he is asking. A wide track Dana 30 (what he has) is perfect for what he is trying to do.

OP, Get six lug outers (balljoints out) off a GM Dana 44 or GM 10 bolt. Bolts onto your Dana 30. If the U joints are different size get new stubs/inners to make it work.

Also depending on what you end up with you may have to change the banjo bolt on the front brake hose. Some GM are 7/16 others are 10 mm- 3/8

Your Dana 30 should I have a 260 U joint. I’m not as familiar with GM stuff but it probably has a 297/760 u joint. If that is the case I would swap the inner shafts and run the bigger U joint.

This is a fucking simple swap and people who don’t know what the fuck they’re talking about should shut the fuck up. I’m all for a little razzing but don’t try to sell the guy a bunch of work to have something that isn’t going to be ideal Jesus fucking Christ.

Unfortunately this isn’t my section, but Gui Keeps a close watch over jeep hard-core. Just report the thread and he will move it.

Well actually No....No you didn't say that...until later. And in this case later doesn't count.

It's all set now though, OP has the info he needed.
