I've got to replace the ballscrews on an old Miyano BNC34T, I've never done this before so its going to be quite the little project full of a lot of learning..

I've gotten a quote on the new ballscrews from Miyano, which I know come with just the screw and the nut.. Thing is, I KNOW there are going to be other pieces that need replacing, but we don't want to get into it and then have to sit and wait a few weeks to find other parts we deem need replacing as we open it up..

When replacing ballscrews, generally, what other items would you replace at the same time?

Thanks..

Thrust bearings and any support bearings. Lube metering units. Have proper sized lube line on hand.

Oh, and axis belts if it has them.
