Isn't this something I can test for? I expect that if I do my regular backlash test (bring the spindle to zero position from both directions and measure the difference with a dial indicator), then I could measure the play/slop in the thrust bearing with a dial indicator on the end of the leadscrew....right? Because if this really is the main problem, yet it would be a no-brainer to try this first.
