I have read the archives regarding moving the rear wheels on John Deere 10, 20, 30, and 40 series tractors. I finally got the left wheel to break loose today. Pinion was rusted up solid. Finally got it loose. Put some pressure on the jack screws and drove it a mile, hitting the the left and right brake occasionally. Right side didn't break loose, but will work on it tomorrow. Question??? How do you guys prep the axle where the hub is going to be moved to? Right now it is painted yellow. Keep it yellow or sand it down to bare metal? Lastly how is the pinion bolt that moves the hub via the gear on the axle held in place? Can't seem to drive them out of the gear with a punch. Comes up to something solid. Is the gear rusted to the bolt? Thanks.
