Bummer Richard,
You might post a new thread, so that MACTEC chimes in. I seem to remember his concern about ball screw alignment on the Z axis.
Sounds like its going to be quite a job. Keep us posted on your progress.
Take pics and video if you can for the rest of us in case we have to "cross that bridge"

I paid about $460 to have my ball screw service.

The wiper on the end of the nut was broken. They replaced the wiper and installed larger balls to take out backlash.
I sent the screw to Rand Industries, a part of Rockford ball screw.
I do not remember why I was looking around in there when I found the broken wiper. I also found the oil distribution block was corroded baldy. I replaced the block and the meters while I had it apart.

Hi, I know its been a while since the last post but I'm having a similar noise along my Y axes and was wondering how hard was it to change out the thrust bearings? Do you have to fully remove the shaft or can you just slide the bearings off?
If I remember correctly you're going to have to at least Slide the screw out far enough to get the bearings off the end.

Thanks for the reply. Are the bearings pressed on and do you need to indicate the shaft after reinstall?
Bearings are not pressed. Not sure about indicating it
