Not sure what "upgrade" they mean. None of the schematics I have show any other version. Not even on the 4540 (New model number of the 4025). Checking those every 10 hours would be a pain, as the front final drive housing has to come apart, requiring a new gasket, fluid, etc. Not something I would do, or have done. I would lift the front end with the fel, grab the front wheel, and check for free play periodically.
