i thought someone would stop me
like 4x4junkie...
I guess the humor must've somehow went over my head
Though I do agree a LOT of information is available by reading the sticky posts around the forum here (also the Tech Library).
But to answer the OP's post, I've wheeled trucks with all 3 suspension types (TTB, SA, SLA-IFS) over the last 2 decades, so here are pros & cons specifically of the TTB I've observed...
Pros:
Nice ride & handling (when set up properly),
Strong/durable in stock form (excepting for the locking hubs, which can be easily swapped for better ones), needs only a few cheap upgrades to handle 35" tires reliably,
Very modification friendly with excellent return on the dollar,
Good junkyard parts are VERY easy to find (at least outside of the rust-belt they are),
Exceptionally tight turning radius (though I haven't quite exactly nailed down how or why),
Nice strong aftermarket for deeper gears and lockers (I'm not sure there is a locker made that doesn't have an application to fit the D35 TTB).
Cons:
Finding competent alignment guys is occasionally difficult (my best guess is training materials that don't properly address TTB suspensions, so some techs are left scratching their heads as they try to guess at it). It's not rocket science though... If you know something about TTB and alignments, it can be done at home using just a tape measure or a telescoping rod between the wheels.
An aftermarket with many pitfalls that are severely outdated and/or poorly-engineered products. Few suspension lifts for example properly address steering geometry out of the box making complaints about tire wear and bad handling prevalent (of course it doesn't have to be this way, there are ways to fix the steering after a lift is put on),
Beams are a bit weak if not braced,
D35 wheelbearings are apparently finicky about proper setup & preload (I've never had any issues out of mine, but there is some number of reports from others who have). The use of cheap (chinese) bearings and mixing of races & bearings (like with new brake rotors) can be a source for problems.
.....
I guess I should ask what your intentions with your rig are (I see you've listed an '87 BII in your profile)... You thinking of maybe a Dana35 swap? Or a solid axle? So far everyone has made comparisons between the TTB axle and the SLA-IFS seen on later Rangers & Explorers, but between a TTB axle and solid, the pros & cons of each are not as clear cut unless you're also contemplating putting 37" or larger tires on it.
