New owner question. My manual steering box has a zirk on top. I was surprised to see gear oil come out of yours. What is the proper lubricant and lubrication process for this. Mine is a '75 if that matters.

Is there a drain/fill plug? I have not looked real hard, but mine only has a grease zirk fitting on top.

This was added by an owner, is a fairly common hack done over the years by people who say 'if you pump the entire gearbox full of axle grease, it won't leak' - which is true, but not a great idea. I can imagine the steering effort at -20F.

Ahh, OK. Well if it hits -20F here in Texas we'll have bigger issues than poor steering effort. I'll take a look later today. Is there a drain or do I have to loosen the bolts and break the seal?
No drain that I know of.
Hillbilly fix: maybe just top it off with 90wt, and make Birfield Soup/Backwoods Goop (if you're an old Mud member, you know what that is...)

Cool, not an old member but have read enough knuckle rebuild threads to know what you mean. There are no visible leaks so I have been holding off on this rebuild in favor of other more pressing issues. This weekend is replacing all of the rotted steering linkages.

Yea, my worn out seals acted as a great drain.
