GoldenSahara00 Then you'd still want them to match but could make the 8.8 wider with wheels and spacers and the 44 narrower with wheels and get them more proportional if you had a full width I suppose if that's what your gona run.

That's why I took a non-CAD housing and welded a sleeve truss over the outside, basically making a 3" x 1/2" wall tube the majority of the length of the long side tube. My thought is that is stronger than both unmodified housings with respect to the long side tube. and that was to run 33s, maybe 35s some day.
That's basically what I thought before hearing that the CAD housing was stronger. I think a non CAD can be made just a stronger with the sleeve and truss like you mentioned. You and Imped and many many others have run hp30s successfully with larger tires. So there is good evidence for the strength of them. I wish some more of the guys w/ experience with the CAD housings would chime in.

Thanks again!
I am installing a 99 ford explorer 8.8 with artec truss kit from ecgs east coast gear and supply. I should be finished next week if i have time to work on it. Lol i will let you know.

Patrick H I replaced 3 housings on two different county owned Dodge trucks due to cracked/ broken CAD housings. I finally convinced the county maintenance that there was some "spirited" driving going on at the local land fill.
Not to say a non-CAD housing wouldn't have failed either.
04-15-2013 12:25 AM
GoldenSahara00 Interesting, thanks guys. So I have people saying it's stronger, some saying it's weaker. Maybe it doesn't matter at all? The CAD can snap in half, but the tubes can bend. They are both weak d30s? I wonder if there is a concrete answer out there. Or if it's just that: both axles have a weakness, pick your preferred poison.

Probably something that could use a little more research.

but to be fair, I've got pics of a HPD30 non-disco cracked in half at the passenger side carrier bearing, and it's cracked right though a big beefy truss. I may even be able to find pics of a HD D44 cracked in half too.

That is what I figured, even with a regular stock housing with the brace it should handle 35 - 37's just fine. I am glad to hear that the front won't be marginal with the Ford HP 44.

Now I can't wait to wear out my 35's.

It's all good, I don't care anyways, It's just hard to tell on the computer sometimes. Your good in my book
There was a thread recently with pictures of a housing cracked in half, but I can't for the life of me find it. If I do I'll post a pic.

Stamped is usually factory but you can buy new "aftermarket" stamped housings. There are variances in material thickness used based on the vehicle it came from, but it's sounds like whoever did the swap knew what they were doing and probably used one with beefier materials. Especially with the brace you aren't going to have an issue.

Actually, the CAD housing is stronger. The multiple piece shafts may be weak, but can easily and cheaply be swapped for the TJ shafts and have the vacuum plugged with a plate. I used to think the same thing about the vaccuum housing being weaker.

x2

Sounds like a well built pair of axles, and no worries on the Ball joints.

Oh in the rear it has a Ford 9" with 35 spline chromo shafts...

I know ball joint life will suffer but this be pushing the ring and pinion and axles beyond reliability?

Yea i know the feeling. My buddy his JK is on 40's I have hard time keeping up sometimes. He will be stepping up to 44's soon so I need to stretch and upgrade the axles on my YJ so i can run 42-48's. But before I can do that i need a daily driver so im building a ZJ with 37's. I love my little Dana 30 so much im gong to put the locker, axle shafts and gears into a HP D30 from a 97 XJ for my ZJ.

It wasn't until I got up on 35's and started doing the Hammers that I finally found places they couldn't go and that includes Los Coyotes, The Rubicon, Big Bear, Stoddard, lots of stuff between BB and Pioneer Town, et al.

Its all about how you wheel. I know people who have destroyed D60 with 37's but my little 30 is still kickin. Matter of fact when I build my ZJ ill be running 37's and an HP 30 up front. I love the D30 its a good axle but cost money to build just like any other axle. I wheel with a few JK's that have the stock 30 with 37's with no issues that ive seen.

village idiot I've been running 37's (MTR's) on the Rubicon Dana 44's, with Superior shafts, for the last 3 years with no issues. I try to be smart with the throttle. Rubicon trail, Moab's Pritchett, Behind the Rocks, Golden Spike, Moab Rim, all that kind of stuff. Nothing's broken yet, I'll let y'all know if anything ever does break.
04-14-2013 12:14 AM
GoldenSahara00 No problem. Blaine is right, and to add to that: You can be super capable on 35s, and there is a lot more to a capable rig than just X tires Y suspension and Z drive train. I would get your axles gears and tire size selected, and built/installed, and start focusing on how to use that stuff to it's fullest potential. Add clearance, as suspension travel and stability, improve handling, steering, traction. If you focus your efforts in the right area you can have a very capable rig for a little less than a pretty penny.
