This is probably a dumb question, but last year my steering seemed to get a little tighter then usual. I know I have to grease the fittings, but I have only found one underneath the engine on the shaft. Where is the other fittings? Do I have to take the engine hood cover off to see them and grease them, or are they all on the outside? I have been told there are two grease fittings for the steering controls. THANK YOU!
