time to replace the D30, - Pirate4x4.Com : 4x4 and Off-Road Forum

wgilbertpt · 10-14-2005, 10:23 AM

Okay I know the D30 and 35" swamper and a full detroit is bad, even with the warn hub conversion. I made it through the year and it's winter project time again. I narrowed my choices to a D44 or 9". Since I enjoy driving it more than fixing it I want to purchase a complete axle that I could weld my own hardware on and not have to mess with it any more. My jeep has a 4.7 stroker, Atlas 2 with 5:1, 35" SSR, rear Currie high pinion 9" HD(dual drilled for 5 on 5 1/2). I will be installing a Rock Krawler 8" coil over conversion on my YJ and trashing the crappy pro comp kit. Who builds the best axles and which one should I buy and why.

Get a 9" with 60 outers, you've got major torque going to the wheels, IMO, 44 ujoints won't cut it.

Bnovak · 10-14-2005, 10:49 AM

Where you located? If you are dumping your 30 as is, I might be interested in it if you are close (oregon or washington?)

Sorry I'm in Maryland

do a front 44, will be enough to handle your 35's without issues. The 760X joints are not that bad, and will survive well with the 35's.

Wgilbertpt, are you doing this swap to run 35's?

wgilbertpt · 10-14-2005, 01:03 PM

I am running 35's now and plan on no bigger than 37's. In fact my 35" SSR's have about 1/2 tread left and when they are down to 1/4 I will probably upgrade to 37" soft compound tires. this is a dedicated trail vehicle now. I am concerned about clearance underneath and think a D60 would be overkill and a lot of unneccessary weight. The 9" or a 44 with upgraded shafts seem to be adequate. I want to be able to buy the axle and install with nothing more than welding my brackets on. I don't want to be the one on the trail who breaks due to inadequate vehicle preparation. I'd much rather pay for it once and even though costly have the confidence that if I try to muscle it through something I will get away with it.

Kreep · 10-14-2005, 01:19 PM

I saw that one coming, sounds like me three years ago.

Do yourself a favor and forget the D44 option. Sure its strong enough for 35's stock or bullet proof with 37's and upgraded shafts, but when you get the itch for 40's you'll wish you hadn't dropped all that coin in a D44.

Ask me how I know. Say, want to but my Waggy D44 with Electrac, 4.88's, Warn shafts and CTMs'? Doh!

wgilbertpt · 10-14-2005, 02:53 PM

So it looks like a Currie High Pinion 9"?

Kreep · 10-14-2005, 03:16 PM

Well, I decided to go take a look at Currie before giving the final thumbs up. I assumed the 1 ton outers and shafts would get you 35 spline axles. Looks like it gets you 35 spline inners which should be 1.5" and 30 spline outers which may be the same as Dana 44 but it does get you the bigger u-joint which is the weak link on a 44.

The site says the 9" will handle up to 37" tires. So if you are SURE you won't go bigger, the 9" gets the nod. Otherwise, you really should get a D60. Don't be stoopid like me.

NE-RokToy · 10-14-2005, 03:45 PM

Get a 9" front with 60 outers and put your rear 3rd member in that then get a HP 60 or LP dana 60 or true high nine or aftermarket nodular 9" center section for the rear

A 9" front with dana 44 outers is a waste of money, all you gain is a stronger ring and pinion but that isnt the weak link in a 44 front end. If you only want 297 sized U-joints stick with a 44 and save a little cash. A dana 44 with alloy shafts and CTM's may survive but would be far from bullet proof with a setup like yours.

Also currie HP rear + 5.0 atlas + stroker +35-37" tires = BOOM!

rockstar · 10-15-2005, 12:02 PM

what ever you do for a center section make sure you are going to have the 1 ton outers. you will regret it otherwise...

wgilbertpt · 10-17-2005, 01:41 PM

New info from Currie. Spoke to Chris who said the Currie high pinion 9" is not happy with 37" tires and he recommended the standard 9". I think I may need to look at another company for a stronger unit.

crtbc · 10-17-2005, 05:29 PM

Whats wrong with telling currie to build you a 9" with 60 outers and no third??? then you can go with a true high nine and be done with it

wgilbertpt · 10-19-2005, 09:06 AM

Since this is a newbie forum, what is included in a D60 outer?

Kreep · 10-19-2005, 09:59 AM

If you are asking "what else do I need" (calipers, locking hubs, etc) you will have to talk with Currie.

If you are asking "what's the big deal with 60 outers" then read NE-RokToy's excellent post.

give the guys at True-Hi9 a call...

00pumpkin · 10-20-2005, 11:09 AM

id do that, get a true high nine case for the rear with the 40 spline

and do the same with the front with 60 outers and 40 spline hi 9 case, and of course CTM's...............ok you dont have to do the 40, 35 will suffice but it would be bling........

You sure have some pretty cool stuff to be asking what is included in dana 60 outers, but usually places like currie use new ford style inner c's/knucles with balljoints....not kingpin........and they can put the outer assembly (knucles/brakes/hubs..etc) on for you or you can get your own stuff.......best thing to do is talk with them and tru high 9

wgilbertpt · 10-23-2005, 03:54 PM

I've ordered a 9" high pinion with D60 outers and ARB 35 spline, clearanced etc from Skunkworks. He sounds like he knows what he's doing as his advice matched a lot of the advice I got here.
