Our 2012 axle has no fittings on the ball joints and there is no hole to thread them into.
The 2012 OEM Steering Linkage has fittings, a total of Four of them.
EDIT: We can claim the non-grease-able ball joints are there to wear out and generate service department revenue. Perhaps, but it's also possible more ball joint failures were traced to the bellows being burst by too much grease/grease pressure, than from lack of lubrication...
You probably have the same four as mine but isn't it strange that the owners manual doesn't mention anything about grease fittings? Even more strange is the the motorhome customer service center folks can't find any mention of zerk fittings in any of their literature. I spent 24 minutes on the phone with a technician trying to find some information regarding this subject with no results.
