Replaced drag link, tie rod, kingpins, steering shaft with new nut and bearings -races etc. quote from OP
Right, I know. That means that wrong or defective parts were used or the steering gear is messed up somehow. Three turns lock to lock doesn't become 4.5 turns lock to lock with the center point being 3 turns greater on one side than the other without there being serious problems with one or more of the components.
Curtis Lee, before you rebuilt the steering system, did you have the same problem with the number of turns left and right being different?
Do you still have all the old parts you removed?
