It's well known that a TTB 44 should have no larger than a 33x10.50 tire on it, anything bigger and you've got a time bomb....


There's absolutely nothing wrong with the TTB axles if they're kept within their limits, I wheeled one for many years and never had an issue. Never got crazy with it, never pushed it passed the limits...


WITH THAT, my '84 Bronco has a solid D44 sitting next to it waiting for me to find the older style radius arms...

There's a place for both, just depends on what you want...

How old of older style radius arms? I have the old radius arms and the stock brackets from my 1990, or are the pre 1980 different? Cause i know that i can use the radius arms on my skyslacker lift with a 1978-79 D44 solid

Desert racing generally utilizes a twin I beam 2wd setup rather than a TTB functional front axle setup. The issues with TTB come not from the ride quality but from the lack of strength that any independent front axle system has

yeah i guess iv only seen the ttb 44s on the prerunners that go through town so your right bout the strength issue. preruuners arent as built up or as fast as the trophy trucks you see in the baja races. so theres gotta be a reason there arent any 4x4 trophy trucks. i just really like the design

yeah i noticed that when i changed my 32-10's for 35-13.50's, thats a reason im wondering on a swap....

often they're old race trucks so they might be down on power but they have the same suspension as the full on race truck because they have to know how that suspension is going to handle the course, hence "pre" "runner"...

If you treat it right the TTB will live quite a while, but if you plan to beat on it like a red headed step child chances are it will no be living very long.

problem with the TTB is the toe changes as the suspension moves. its constantly going from toe-in to toe-out. thats one of the reasons for horrid tire wear. second is worn bushings.

the coil spring TTB has two pivot points, the axle bushings and the radius arms. when the truck is lifted, generally the axle beams are lowered with brackets and either longer arms or drop brackets are used for the radius arm. once the factory geometery is gone getting it back into spec is hard. adjustable camber bushings work but the TTB has a lot of load on those pivot points, so even if everything is new there is still a lot of stress on those brackets. i've seen both sets of brackets work loose over time. that is another reason i dislike the TTB on a lifted truck. tack welding and using lock-tight is a good idea to keep everything from working loose. not to mention the adverse effect on the steering from the larger tires on the y-link steering linkages and the constant movement in the toe its not a real good set up. it also seems if the allignment is spot on after the truck is lifted, a few good bounces and its all out of kilter again. just my experience.

i have done several solid axle swaps in the 1/2 tons and everything was 10x better. my vote is solid axle over TTB, unless its being kept stock or with a good quality lift (extended arms, rancho style drop brackets) and everything is kept an eye on.

What I did was had*them install the stiffest springs Ford made
that'd fit my '75 F150 and that helped a lot. It rides good too,
real-firm but not harsh, everyone that rides in it likes it.

I reduced the front tire cupping problem by setting the toe as
close to zero as I could get it but between zero and 1/32" in.

Also adjusted my ride-height (as Ford calls it)...

It drives and steers great, took it to town again today.

Some of this little stuff you just got to do yourself because
no one else is going to take the time to do it for you.

well i beat the ttb with 39.5-15 swampers last winter, knee deep sharp snow for like 6 or 9 hours, forgot. but it was rough as hell. another reason....

I have a F350 which has the solid, and 2 bronks, and just sold my F150, so I have all setups lol. The F350 with the solid is mega tough, rides like crap(bilsteins helped alot), the 1 bronk 88 302 aod 147k, orig suspension. I have had no probs with waring tires, I use it as a work truck with a trailer that is the same size as a 8ft truck bed. I will be gettin a 4" lift soon for it, and will be keep the TTB as its already there and has no probs, for what my bronk sees, its gonna be fine. The other bronk, 94 302, e4od, 155k, with a 4" lift. I bought it to take the lift off for my 88, but had more fun beatin the piss outta it in my back yard jumping it and whatnot. Now its got the TTB also and it didnt break or anything with all the jumps I have done. I even managed to get the air bag to blow up in my face and suspension in tact. Now the 92 F150 was the same setup as 94 bronk, but with, about 3-4 in suspension and 3-4 in a body lift. I hated the body lift on the truck, really messed everything up, truck was sick, but had to sell caus of body lift(got it for cheap the way it was) I would go 4-6 suspension lift only. If your not doin anything serous then the TTB will be fine. I have more respect for the TTB because of 94 bronk lol.

First chance you get id swap ina solid axle, a dana 44 would do but go big or go home and go with a dana 60, and id suggest rebuilding it before you put it in lesson learned the hard way..
