Yeah my truck does the same thing. Replace OEM ball joints with Dynatrac's, new sway bar end links, and N49 recall. I have a low speed front end clunk and the truck is quite the handful on the highway. Seems like it is all over the road. Just put the truck up for sale. I'm getting tired of it..Just drove it in a down pour. ... Damn right scary to drive this thing. It follows every friggin crack, line, I'm fighting to keep it on the damn road.
I'm pulling my hair out. Drives like it's on ice skates....darts back and forth.
