Funny, i always wondered why "east coasters" seem to be going in circles,
but seriously.
I have replaced the center link both tie rods, new bilstein shocks and steering stabilizer, and all the misc suspension bushings except the lower ball joints- those are next... could it be the ball joints?? doesn't make sense

think if some suspension were rubbing I would have seen... but i'll look again.

the only major change from before the problem occured is the PS box rebuild, but why only in one direction
I know it is a recirculating ball type, would something allow the balls to move up, but not down, or visa-versa. (besides any funny trampoline jokes)

Engineer types out there??
anyone rebuilt one of the W126 steering boxes remember something inside that would change directionally the PS fluid or block it nearly all the way??
