All new ball joints, tie rod ends, spindle bearings right? Rag joint? steering column tight?

Did you replace the steering box and pump? could you have gotten a bad one?

try setting the toe in a little narrow in the front, when you drive down the road it will want to try and widen a little.

Did you get an idea what the camber is? i cant recall the spec but check it to see that its close.

my truck was darting allover the road untill i rebuilt the Dana, it still wants to wander a bit but i will be replacing the steering box soon with a init from Readhead steering.
