Can/should I beef-up a Dana 30?

If I upgrade the axles (Warn's), Hubs (Warn's), and U-joints (CTM's), can I make a Dana 30 just about as strong as a built Dana 44? Where would the week point be (the hub, right)? I would think this would be a very ecconomical way to run ~35"s without breaking (compared to having a complete 44 or 60 built). What do you think?

[no way. I ran 35's for a little while but with no locker. and if you try to drive over a stone you will be straightening and strenghtening your tie rod

lets look at all the screwups so far

1) (obviously) you didn't search or you would have found a thread less than 2 weeks old on the same subject
2) you cross posted the same Q in the jeep and the general boards
3) you didn't say what kind of a dana 30.

I did do a search before I posted this and found almost no information. There was plenty of BS and "don't do anything smaller than a D60," but almost no actual information. Thanks for that one link. I didn't find it in my search. It had some nuggets of info hidden w/in all the crap.

I'm talking about a CJ Dana 30. Aren't the knuckles the same (30 vs 44)? It just seems like such a waste to buy a 44, narrow it, and fill it with all the "good parts" if it won't be any stronger than a 30 with the same "good parts". Apart from the axles, hub, and Ujoints, what is the real benefit of the 44 over the 30?

I may be 'new' but I'm trying to learn. Does any one have the answers to my questions?

What you suggest doing will give you some additional strength, but there is one big problem there is no way around. If you go with decent gearing, say 4.56, 4.88 or better, your pinion gear to ring gear contact is PUNY , you will have a half a tooth contact at any one time on a very small R&P, a recipe for disaster.

dont waste the cash either keep the dana 30 stock and leave it alone, or go to a Dana 44 beefed up or even a front Dana 60 if you got the cash but dont waste your money on overpriced Dana 30 bullshit.

with the 297X's in the 30, the 44 won't be an upgrade.

Thats not necessarily true... you get 3 more splines with the 44, a stronger housing, and a bigger ring and pinion.. thats an upgrade in my book..

Don't forget the thicker tubes, bigger spindles, bigger steering gear, bigger tie rod ends, bigger balljoints, bigger brakes, and bigger bearings.

Yeah, I'd definitely say the 44 is an upgrade.

What's so fricking funny about this topic. Sure its been asked before, but not everyone can afford time or money wise a completely different diff in their vehicle. Its people like you that are a joke if you can't understand that. The point is this guy wants to wheel, and do the best with what he's got, can afford, and can do.

You can probably pick up a 44 & have it shortened for the $$ you will put into your 30

I ran 38X14.50 with Ox locker and 4:88 R/P with my 30 and 35 with detroit on the rear on my TJ, I have no problems. I've been to hard trails, you just got to know how to drive it. I've seen people with 60 and still breaking it..

Hey Brad,
Ease up a bit. The guy is new and just trying (albeit a poor attempt) to fit in. I think he was refering to the flame crap at the start of this post that's all.

As to the Dana 30, I would not waste the money, put the money you want to spend on fixing up the 30 into the bank and keep saving, so when you break the 30, you can replace it with a D44 or something better. A piece of shit in a tuxedo, is still a piece of shit.

I just have this to say, yes I am newbie to this board but not to jeepin. I have a '98 TJ that I have been wheeling hard in clayton, ok. I have ran just about every trail there many times.


I have a upgraded D30 and have no problems, i think it is all a matter of who you drive it. I have ran boggers and Xterrain tires with no difference.


You read my signature and see what I have done, with no breakage. I don't even run CTM's yet.

And replacing blown axles due to exploding u-joints on a 44 is better than doing the same on a 30 how?

You are talkin affordable, and what you say makes sense, but from how I am understanding him he wants to spend a BUTTLOAD of money on the D30
