Some folks like to use the John Deere corn head grease for the steering gears due to problems with seal leakage. Originally, SAE 90 was the recommended lube but a bad seal will mark a spot. A new seal should hold it OK. Many of the steering gears have a phosphor bronze bushing inside so they can be affected by GL-5 lubricants. GL-4 or GL-1 rated lubricants would be OK.

Rear axles have no yellow metal in them and can use any gear lube you want to use as long as they meet the recommended SAE rating for viscosity.
