Ready Steady Eddy

Well, not even that, I just want to buy them and fit them knowing they will work as expected, is that asking too much ? I don't think so.

Anyway I stripped the Y axis ball screw out and laid it on a flat surface, sure enough it was bent about half way. Using a feeler gauge I slid it along underneath to find the bend position, then I put it in a vice with wooden jaws, put a pipe over the other bit and 'leaned' against it until it was straight. Now it's about right however the ball nut is a bit crunchy, I pumped some grease in and the metal particles that came out was alarming, it's still a bit rough and sticks now again so I see no alternative than to strip it out and clean, that's assuming it will go back together.
