Give us the complete picture, in my case, the steering was fine until I'd hit a bump with the wheels turned slightly. Then the front end would go crazy until I brought the truck to a complete stop. Then, it would right itself and I could drive again.

Did it come on with impact? even very slight impact? Can you make it happen at will? When testing, Id hit traintracks with the wheels turned and feel for vibration.

My first thought was to change everything too, but the aftermarket steering stuff may not be as dead on as stock. And the stock components are pretty beefy. Once we got to the problem in my case it was an easy fix, but we used stock components to be sure to preserve the geometry.

I have a big ass RK solid steel track bar.
