the TTB can handle bigger than 33s. i have 35s on mine, and it is fine. the TTB is independent front suspension. large tires put wear on it, as they tend to sit funny after time

the rear is a solid axle, which is stronger for bigger tires. i personally wouldnt put 37s on an 8.8

That sounds backwards to me. I'd rather put 37" tires on the TTB D44 than 37" tires on an 8.8" rear. Both are a bit undersized for 37" tires, but at least the D44 is a full floating axle.

I've run 35" tires on my TTB D44 since 1999. I've had minimal issues, only replaced balljoints once in 2002. I grenaded my 8.8 and replaced it with a 9" by 2000, bent the housing on the 9" by 2002, built a trussed 9" which is fine sofar. My truck doesn't get much mileage anymore, but what it does see is almost all offroad either crawling rocks or going fast.

I'm not suggesting the D44 is strong by any means, but I haven't broken one. I have broken an 8.8 and a 9" on the same truck. Maybe I'm just lucky, or maybe I stay off the stupid pedal in the rocks.

I am running the Warn hub fuses in the front hubs. I don't know if they'd preserve the u-joints or not, but with the front ARB it seemed like a good idea.

I run 34" LTB's and a locker in my TTB 40/50 - but I also run MM Supreme lockouts, moly outer shafts, spicer joints, and a D50 3rd member and stub shaft. Holds up to my wide open throttle wheeling style and 4.56's - even some airtime.

While I'm not a huge fan of the Dana 44 the 8.8 is amazing and you sir are on crack.
I have heard alot about the 8.8 not all are good things. From what I've heard. I ain't casting judgement or nothing its just personal preference. I was always a huge fan of the rockwells though. heheh

Besides I will never do a drug named after a part of my own ass. :toothless

definatley not pos axles they are just fine and plenty strong for most applications. also the ttb has pretty amazing possibilities proving that they can be strong. go look at the bronco speed forum.
When I say POS I mean souly on the TTB side. I can't ever get the thing aligned straight. I have almost replaced every component too.
I dream of straight axles with airlockers.

It's like anything, you can get a good axle or a bad one. I use to break 7.5 axles (shot spider gears through the diff cover) all the time but never had a issue with my 8.8 in my Stang. I had a lot more HPs in the Stang but it weighed a lot less.

Rockwells are great and they still break from time to time. I'm still wanting to get a set of Rockwells to do a SAS.

Stay off the plumbers crack I've heard it's really bad...

Youre running 38s with the stock gearing? I bet that thing is QUICK. :goodfinge

My TTB setup aligns well and handles better than a solid axle at speed. It is definately a compromise on strength, but I'll take it for the ride.

My daily driver is a solid axle 3/4 ton diesel. It handles decently, but my Bronco is much better in anything rough.

Your question is basically just leading to a ton of opinion.

you could go and put 40's on these axles if you left them open and drove around malls all the time.

use a bronco hard out on trails and I'd say the limits are usually around 35's for both axles. This opinion of mine comes from 1) experience owning
2) seeing what others' experience has been (good and bad)
3) knowing that stock D44 axleshafts and joints usually can just handle 35's with open front, careful wheeling, and stock motor
4) 8.8 rear has a tube to diff issue so spinning the tube or bending it is what I've seen mostly with this axle used offroad. This can be helped with a truss and weld. If equipped with a limited slip carrier, so much material is removed for accessing the clutch plates, the carrier itself becomes a weak link. Use a detroit or something and problem solved there.

Everyone has had a different experince. I've seen 8.8 and TTB 44 run 44" boggers with a 460 behind them (other than regular things, ball joints,alignment,etc) the dude never broke or twisted anything. But all we have is mud, no trails. Then again I seen the 10.25's , 8.8's and ttb 44's snap like a toothpick with 36's (I think). I guess it depend on the "playing conditions".
