So first time I have done a steering arm replacement on my 4700. I had the old hydraulic cylinder still that can not be serviced, as I am putting new cylinder in I notice that there are no grease fittings for the ends. There are boots present on each end but no grease fittings? Is this wrong or do I have to do something to add grease fittings? The schematics don't show one but it doesn't show on the old one but it has them.
