I worked in a local shop in the early 80's. I got to see plenty of these new or barely used. Ford warantee was only 12/12K back then, so when they were not right, they didn't all go back to Ford. IF you do nothing but drive down perfectly straight smooth roads with the smallest tire (235), then maybe. As soon as you load up gear, tow, put plow on or off, as you have shown, you get severe toe changes that tears up tires. I agree, many issues on older lifted trucks were worn parts. But stock TTB's wear parts faster than SA, RA, as the entire geometry is constantly working against itself. Tie rods not correct arc vs traction beams, Radius arms too short (much shorter than stock SA rad arm susp), constant camber changes. Even a minor spring settling more on one corner than the other, and you have cross caster issues. Most swapped out TTB to get rid of these issues, not to gain strength, as most went to a 70's full size D44. We can agree to disagree, but TTB gets a bad rap for way more than worn parts. Stop posting up videos of perfectly dry, high traction terrain. Near me, even if it's not totally wet, there is still low traction rocks, moss, wet leaves, slippery barkless trees, and mud tracked all over everything. I wheeled recently with some toys and they busted CV's left and right, doing very stuff you show in these videos. So some of you had said they use weak parts. So lets see some vids of IFS (even beefed up stock configurations) GETTIN it. It is pretty easy for many backyards to mounts and swap/upgrade a solid axle. Not so much if you have to fab control arms that hold ball joints and bushings.
