Call Kitamura at 847-520-7755, ask for service, and have your serial #. They are there from 7 am to 5:30 pm central time and are your best source for technical questions regarding your machine. They will have a PDF they can email you regarding tips on removing the ball screw or replacing the thrust bearings. For parts you can buy direct, like the Lube pump and other odds and ends, I have found their prices are about 10% more than the best I can find so I would say buy your parts from them, through your distributor as they don't sell direct. This way you know they are correct and it helps support their FREE tech help for anyone who owns a Kitamura.
Before pulling things apart you should figure out if it is your screw or thrust bearings, it is much easier to do while in the machine. There is a vast difference in quality between a rebuilt vs new screw assembly, and a fair amount of work to install it right, so if it were my $$$$ I would go new. This way you can have the parts on hand to install after you pull them and don't have to wait weeks to get your rebuilt screw that will hopefully work and last.
Mine has .0002" lost motion in the Y axis thrust bearings.
