Looked to me like the inner tie rod just threaded down right to the end of the ballscrew on the EPS.
If thats the case, easy-peasy, just pop outer from knuckle, and unscrew the inner?
Also looked like there is a large threaded piece that holds the ballnut in place on the EPS unit, my concern would be not overtightening that and binding the ballnut. Looks like the ballnut spins in place, and the screw moves right or left to steer?
Please, correct me if I am wrong about this. I'd like to get a better understanding of it, just in case, cause I damn sure cannot afford a new EPS if mine decides to take a dump, esp if it's only a belt.
