can't have this type of info getting into enemy hands

That is true, it still seems like you have enough cool projects anyways.

having to align one TTB is enough, why add another?

aligning ttb's is easy....you just need to know a few tricks.

Says Merlin to the Knights of the round table.........lol!

there's very little that i haven't done with ttb.

on extreme 4x4 today,i saw a teaser pic of a high clearance diff they are going to be putting in a jeep-a design i built 10 years ago from d50ttb parts.between that,the pic in this thread,and the 4 linked ttb posted earlier,i was reminded of how many different things i have done with these suspensions.

and yes,there are more.

 

[wrecking-crew]

I might have to ask you for some installation tips gwaii.

 

[gwaii]

hopefully i'll have some answers.


my specialty is doing things with these systems that no one would think to do......well,almost no one.

i've studied the geometry of the ttb to death.used to sit at the table for hours with a big sheet of graph paper just drawing out curves for different systems,figuring out how to make it work better.
come up with some odd ideas when it's on paper...takes a lot longer when i'm making them from metal.

Wow. Under your name should be...

"TTB GURU"

I've been called that too. I dunno... To me it doesn't really seem much different than anything else. The suspension industry sure did a heck of a good job botching everything up when it came to designing suspension lift kits for it though...

agreed.

and like you say,it's not so different from any other suspension,uses all the same principles.

i think a lot of people have a problem with it because they haven't learned enough about it.a little time studying,and it all becomes pretty simple.

but building all that stuff is still a lot of work.i've installed a lot of factory kits in other peoples trucks,as well as built custom ones for those ready to part with a bit more cash.
i've never used a factory kit on any of my own trucks.

Aside from the millions of F-250's with the TTB D50, 80-85 F-350's had them too.

this is true.

while i question their suitabillity to their original purpose,they do supply some ok parts for building other stuff

Dad has 270k on a '80 F-350 service truck, only repairs to the front end was a hub that an employee didn't disengage all the way and ground up, another hub that caught something and ripped the end off, and the slip part of the front driveshaft wore out. Of course balljoints and TRE's and normal wear stuff like that too.

Pretty much a stock truck living up to the original purpose of the truck... with typical company truck treatment.

the components are plenty strong enough for their intended use,my issue is with how variable the loading can be on these heavier trucks.
with a one ton truck,there is a large difference between the loaded weight and the empty weight,and while most of this load goes over the rear axle,a certain component of it ends up over the front axle as well.
the alignment of the ttb is hieght dependant,so a loaded truck will need a different alignment than an unloaded truck.this is less of an issue with lighter trucks,such as the ranger and even f150,but if an f350 is aligned properly,then a camper(or other large load)is put on it,then it is taken on a long road trip,for the duration of that trip the alignment will be out,unless the truck is re-aligned for the load.then it will need to be re-aligned again when the load is removed.
this also happens,but to a lesser degree,with sla systems,but not with a solid axle.
this is why i question the suitability on trucks designed to carry heavier loads.and,i'm sure,why ford only used it on the f350 for a few years.

From reading in that jeep thread it seems they are close in length just the mounting points are different which is why people think it is so much shorter.

The mounting points on the truck are different. If you bolted a d44 TTB in a D50 TTB truck you would end up with the drivers side wheel sticking out much farther than the passenger.

Here is a pic of the beam difference.
