Good morning,
Thanks to all for your input. Here's what I discovered in the last week. Car had ALOT of Ackerman, too much positive scrub, and some rack-induced movement in the shackles. The bump steer is negligible (almost nonexistent) throughout the range of suspension travel.
Going back together today with new steering arms (very little Ackerman) and a shackle-less spring mount on the drivers side. Still searching for the correct hub/wheel combo for the scrub radius.
I'll try the water trick when it's all back together and keep you posted.
Thanks again, Pedro
Godspeed Cliff Gullett.
