According to my 340 manual the original PS lubricant was 3 1/2 pints of Hytran, which is about a 20w oil, or "worm gear lubricant", which I take for 90w.

Corn head grease is a light lubricating grease, lighter than bearing grease. I believe corn head grease is a #1 grease, while regular bearing grease is #2, but my memory may fail me on that.
I learned the hard way that tapping the end of the steering shaft while trying to remove the steering wheel with a puller at least on the 340's PS is very likely to push out an expansion plug, and quickly drained the PS housing. Faced with that dilemma, I pumped in 2 1/2 tubes of JD corn head grease, the leaks stopped, and PS works fine.
