Roger Actually, this is not quite correct... The trunnions require oil: a hypoid gear oil is the best for this purpose: it is designed to be used in extreme pressures between gear teeth, and does coat the threads properly, as indicated by the factory requirement. A grease is not a good option- while it does seem to work ok, it also hardens, and does not provide proper lubrication of the trunnions. The service manual, IIRC, specifically states to not use grease... You will find a higher incidence of wear due to the grease. I always use hypoid gear oil on my trunnions... Scott
