Manual Steering Box...assistance needed...

Yes,
The manual says to pack it with grease on assy.
(I use red Mobil syn. for eveything. It high temp, high press. and water proof. Save buying different kinds of grease)
People put oil in them because the seals go bad.
The grease dries up or leaks out.
I'll post the manual ref. later tonight.
Not much to it.
