2005 Ford E-450 grease fittings August 31, 2005, 11:54:16 am Yahoo Message Number: 57496I found four (4) zerk fittings on the front steering linkage. The grease points are sealed-membrane-enclosed and can easily be carefully pumped back to "full".Are there more than four zerk fittings? Is there a Ford motor Co website that shows a diagram of the fittings?Many thanks!
