FORD SPEC calls for S.A.E. 90 for STEER BOX pre-1958 (worm gear TYPE).

1958 on SAGINAW Box (recirculating ball type) used a special STEERING GEAR LUBRICANT which is not the same as chassis grease.

If you find a grease (many types) in a pre-1958 box, you have had something done by someone previously that did not use a LUBRICANT CHART or was trying to correct/hide something.

To properly fill a 58/ box with lubricant, turn the wheels to the left. Remove the SECTOR SHAFT COVER cap screw furthest from the fill hole. Fill box with grease gun until grease flows out that removed cap screw hole. Reinstall both the cap screw and the filler plug. Turn wheels to right and repeat fill procedure.

It that cap screw is not removed to indicate full, one may overfill the box especially with a gun using air.

1957 GM SERVICE BULLETIN –

Lubricant recommendations for 1955-57 passenger car steering gear have been changed to discontinue the use of #8216 - Multi-Purpose Lubricant and recommend in its place Chassis Lubricant #8217.

Coincident with the change in lubricant recommendations, service personnel are advised that the steering gear lubricant level should be maintained 3/4-inch below the filler plug hole instead of level with the filler hole as previously prescribed. The reduced level lessens the possibility of lubricant being forced out of the steering gear box during the pump action that results from fast turning of the steering wheels.


GM must have used grease rather than SAE 90.
