Is this the easy fix for TTB alignment/tire wear nightmares?

This is what needs to happen.

exactly.

while the stonecrusher is an improvement over stock,it still does not put the tie rod pivots in the optimum location,nor does the superlift system.for this a drag link with idler arm must be used(as with the superlift),and the tie rods pass each other.the superlift system would be better if the left tie rod bolted to the right mount on the drag link,and vice versa,thought to optimise it those mounts would need to be relocated too.

That may be true, however it's still a VAST improvement over a stock linkage on a too-short drop pitman arm (as is usually the case on a lifted vehicle).

The Stonecrusher setup is an excellent compromise that adds essentially no additional complexity to the setup unlike the K-link (Superlift) or crossover setups do (bringing tire wear completely back down to negligible levels).
I really don't see a crossover setup being necessary if you're not putting the suspension to it's travel extremes constantly (running the Baja for example).

this is true,but i was looking at a theoretical optimum,not an improvement over stock.for what it's worth,the stonecrusher has far better geometry than the superlift(i don't know how they've swindled so many into buying those things)but for an example of the optimum,regardless of it's complexity,the picture above is as close as you're going to find.

Well, I guess I must be one of the ones that they "swindled" lol...

Had the Stonecrusher linkage been available 5 years ago, I might've considered it, but the Superlift (with it modified it so that the centerlink is actually on the same plane as the axle) does work rather well too. I bought it knowing it had this flaw, and dealt with it accordingly.

i've used the superlift as a starting point to build a system similar to the one pictured above,but in it's out-of-the-box form,the tie rods are pivoted nowhere near where they need to be.
my issue with it is that they market it as 'the cure for the ttb steering problems' and combine it with longer travel suspension kits.if they were going to engineer a new(expensive) steering system,they could have done much better.bump steer is still very significant with this system.

Oh I agree 100%. They apparently had monkeys substituting for engineers when designing their TTB stuff (and still do... or at least they don't seem to care that their stuff has sucked for decades anyway).

well this one would work though wouldnt it?

Yes it would.

 

[bobbywalter]

Yes it would.

yeah, thats a good comprimise


using various oem pieces i found some good setups. all had odd quirks though in one form or another so i dont list shit like that too often...

while these are old pics they show what the result is...a distinctly non ttbtard steering camber stuff

cant stuff it any more than that can ya?

hope the pics work
