In most cases, eliminating tires, worn parts, etc, it is negative caster causing the problem, through all the parts and money ya want at it, it will resurface again until that axle is rotated in the correct axxis, yes they do come from the fact that way, where close enough works and a cpl thousand are built everyday

Key word on your truck, adjustable radius arms, they are the fix, Put a leveling kit and 35s on my jeep and it was a handful to keep going straight, downright scary, lift kit said no other mods necessary, b s , i measured pinion angle and was way off 4+ caster, i got some adjustable locating arm brackets and got it right at 4+. 80mph and you can take hands of steering wheel, if you choose. lol. any easy fix if i get this wobble, ill skip the dealership for a correct fix, but i suppose the adj rad arms arent cheap?

I am not an engineer, or even more mechanically inclined than the level of a mediocre backyard mechanic, so here’s my input.

If increasing the caster settings fixes the geometric alignment, why hasn’t Ford tested this and incorporated the new settings in their builds? It sounds like a fairly easy fix, with no real downside. It’s cheaper than throwing parts at it, would lessen the risk for lawsuits, and would create goodwill with the owners.

Me not engineer either, lol hell can barely spell it, I don’t know the answer, Jeep wranglers are the same way, some shake some don’t, some are so close to neg caster that adding a 100 lb winch to the front sets up the wobble. It’s seems to be the solid axle vehicles and not much of a caster degree window, not sure if this part of the assembly line is man or machine. Steering stabilizers have a function, bump steer mostly and off roading but i would look for the cause of the wobbling first,

It is my belief that there is no way the dealer can adjust the caster, hence the steering stabilizer miracle, and alignment b s , the correct fix is adjustable radius arms, There is limited if any possible adjustments on stock radious arms. For some reason there is enough factory tolerances during build that it’s close enough.

It’s def a nail biter, I remember the death wobble on my 82 Suzuki gs 1100E at 120 mph, either ya had the ***** to throttle through it or back off and hope it didn’t spit ya off. Either way time to check your shorts, ��

See what age does to ya, agreed tank slapper, lol. All because of sum sticky Dunlop tires. Be it 2 wheels or four, it doesn’t take much to upset all that engineering

exactly, it also messes with drive shaft length, it’s a fine line of harmonics they engineer it to
