you could spark a week long debate on this, but some like 85 140 gear lube, some say straight stp, if you have a leaker some like john deere corn head grease. you could pick one, or wait for the roar to start! happy motoring

I read here about straight STP. And they had it at the grocery store, I put it in, feels real good.

My otherwise smooth and tight steering ('41 Coupe) dripped dry. Replaced with 600W gear lube (the modern Mobil version) and it also leaks. I recently filled the steering box with corn head grease to see if that will stay in the box.

Cornhead grease in my 52 Merc (and a few others) steering box for a while now. Seems to work fine and sure cut down on the leakage.

If it leaks, use corn grease.
If it does not leak, use straight Power Punch or STP for greatly reduced steering effort along with long gear life.

I've been using Penrite. Problem is, if you add cornhead, or Penrite, or any other similar, on top of something that leaks, then it's still going to leak, at least until the last of the leaky stuff works it's way out.

I use cheap chassis grease with molly D The box is close to
to the exhaust and keeps it soft. Lots of old Fords with it in
and no leaks. G.M.

Ha, never thought about cement to repair leaks.

I do use a mix of JD cornhead and 300w I still have left. Works fine, so far. Probably the last thing anyone ever thinks to rebuild/re-gasket, but should. Me included. Not that it leaks bad or preforms poorly.

Thanks Rand
Decided over 10 years ago to remove the original felt dust seal and replace it with something better on my '51.
Have not seen any drips since while using Amsoil synthetic gear lube.

The 49 through 51 Mercury cars have a heavy duty version of the Gemmer II gearbox. They have a larger sector shaft than Ford cars ever had up to that point. The bushing can wear and allow more than normal movement of the lower end of the sector shaft. This can cause seal damage over time. I've found these bushings on flea-pay but I think there are still a fair amount of NOS ones out there since they were originally for Ford truck gearboxes. The sector lower seal is available at most of the restoration parts suppliers. When everything is sealed up, about any good grade of gear lube will stay in there pretty well. On a leaker, I would use the HD corn header grease. As a thixotropic grease, it coats gears well when moving and solidifies at rest. Those JD corn cutting head gearboxes have a shaft going in and several going out so there are multiple places for the seals to leak. This is why JD chose the stuff. They may still have a video on their web site showing a cut away gearbox functioning with the stuff.
