I do know about not putting GL5 in the transmission. Back when I worked in industry we had equipment with brass gears we were not supposed to use GL5. Seems you should not use it in ModeT truck rear end either.Corn head grease for the steering box too.
Just do not put that gl-5 oil in your transmission. NAPA can order some gl-4 for you.
Many use the corn head grease in the steering box also, I have not tried it yet.
Many 8N ford owners use it in the steering box as well when the box leaks.
I am going to put it in the clam shell in several sessions as I about wore out my arm pumping today. Had an air powered gun which went bad, a battery powered one is the way to go now I guess.

True, NAPA can order, at an exorbitant price from an outfit I never heard of. Why would GL4 be more expensive than GL5 when GL4 is missing the Sulphur additive? Two quarts would be well over$100. I'll keep looking.

Eastern TN Tom, I also don’t know why 90w gl-4 gear oil is so expensive. OReillys has 140 gl-4 for a much more reasonable price.
I will have to check Walmart, did not think of them.Something is not right with that price. Oddly, I can't seem to find the gallon size I normally order. I did find a 5 gallon can of CRC/Sta-Lube 85W-90 for $190.

Delux cars got the spring covers
Grease in the springs will not migrate to the tips when it is needed although if you have no or weak shocks you need a stiff springs to dampen movement.
The ride in a car with properly lubricated springs and properly working and adjusted shock absorbers is much different.
If you look at your springs and there is red dust or red grunge coming out of them they are not properly lubricated.
previous greasing with chassis grease clogs the built in passages preventing lubrication from reaching the tips of the leaves.
1941 Mercury all had spring covers.
You are spot on with your advice in regard to NOT using grease in the springs.
When I had finally used up my five-gallon pail of Ford Spring lubricant, I switched to SDTP oil treatment. Nearly the same consistency as the Ford Lubricant and just as easy to install.
