This is why modern grease is suitable for use in Model "A" steering gear boxes! A common feature of modern greases is that they possess a high initial viscosity, which upon the application of shear (sliding / rolling surfaces), drops to give the effect of an oil-lubricated bearing of approximately the same viscosity as the base oil used in the grease.

In the case of the Model "A's" steering, initially putting grease into the gear box seals the otherwise leaky sector gear bushings. Follow the grease with SAE140 synthetic gear oil and you will have a cleaner garage floor and driveway.
