so I was thinking of buying the terra flex HD d30 replacement housing but I wanted to get some feedback from more experienced jeepers.
I have a 2012 jku auto w/AEV 3.5 lift, 35" trail grapplers and only run green and some blue trails. I want to run 37's and not worry about bend my housing or c's while running the green/blue trails. I will be having new gears and ball joint installed at the same time.
does anyone have any info on this d30? does this sound like a good option for the type of wheeling I do. all reply's appreciated! unless you being a smart ass

 

Honestly, you could find a better option for the same price. What is your current setup?

 

i have stock d30 w 3:73 gears, auto. on 35's

 

If you are spending $2000 on a bare housing and then filling it, why not spend a bit more and look into a front d44?

 

I just got my 2012 back today.

My jeep is now ready for 37" tires if i bump up the gears to 4.56. I would not go into deeper gearing with the D30 as that is the only weak point on the diff compared to the D44. 4.88 gearing is fine if you're a light foot overroader, but im a lead foot and wont go passed 4.56 gearing. Its plenty low enough.

 

I'm running 40's with 4.56, does hreat

 

I have a dana 30 in my 2 door with 37" Nitto mud grapplers on steel wheels. I did the eVo sleeves, eVo gussets, eVo lower control arm skids, artec truss, a riddler dif cover, an Aussie locker, 4.88 USA standard gears and Reid knuckles. I spent about $600 on parts ( not including the Reid knuckles they are universal to the jk so I can use those when I build up a dana 44 ) welded everything myself and am fully confident that I can wheel it hard. Even with my stock shafts. Though I do have a spare set when I wheel.

So as far as spending $2000 on the tera30 my answer is NO BUY A TERA 44 !!!

 

what did all that cost you in us dollars. I'm trying to decide whether it's worth the little extra to buy a beefier housing and not have to worry about a bad weld due to a shop rushing the work.

 

I'm in a similar situation as the OP. I don't see the Tera30 and Tera44 as being comparable products to a person like he and I that have a complete Dana 30 already.

For some of us, the ring and pinion isn't an issue, some of us don't wheel hard core. Look around for the hundreds off threads about D30 gear failures in the JK. They aren't out there! Now look for bent housings, you find a never ending supply of threads with bent housings, so to that point, and the fact that with 3000 miles on my 2014 Willys my front axle bent. So what I need to "fix" is the weak housing not the ring and pinion.

You can hunt used our take off parts, maybe pay $800 for a full D30, but a factory new bare housing for $1300, buy a factory new complete assembly for $1800 or buy a Teraflex for about $1800-$2000 and never worry about it again.

The Tera30 housing gets a bad rap, and your told that if you were going to buy it, buy the Tera44.... But the Tera30 doesn't cost more to us 30 owners than the housing. The 44 will take another few grand to load with parts unless you can buy a used Rubicon to donate parts out of.

For me, I've got $2000 to work with, and in that range I've got options of used assemblies, new housing, new assembly it Tera 30.

I don't have $3000, $4000 or $5000. So, with $2000 to play with, a jeep that will maybe someday go to 35" tires but will never be a hard core wheeler, a Dana 30 built on a Tera30 it's a fine way to go while living in a budget. And even should the gears go one day, that's a way cheaper fix than another bent D30 housing.

My vote is leaving towards a Tera30 housing. I just don't see the Dana 30 ring and pinion as being the Big problem, the Big problems are the junk tubes and C's and that is exactly what the Tera fixes.

 

A terra 44 is 200 more and then I can't use anything from the d30, which means a lot more money. my 4:56 yukon gears and overhaul kits alone cost me 539.00. also I can't weld so thats not cheap here in MD.
