So the ball nut has a flange on one end? Would you need to remove the ball return tubes to press the bearing down the length of the body to get one bearing next to the flange? Guessing here since I do not know what your ball nut looks like. If so, careful of any burrs that may have been raised when the body was machined for the holes associated with the return tubes. > > > You should be aware of lubrication issues.
