I know that I will raise the ire of some with this but, I would not
recommend any type of grease unless it becomes a liquid at normal operating
temperatures.
My problem with grease is that the steering box rocker shaft runs steel on
steel at the top the tube of the steering box. I have rebuilt quite a few
of those boxes and encountered considerable wear of the shaft at that point
when they have been low on oil, as in empty, or have been filled with
grease because the grease does not seem to get to that area.
As for changing the seal without removing the box it is possible. A small
pitman arm puller can be maneuvered into position to remove the arm then it
is just a case of digging the old seal out with an ice pick or dental hook.
Replace the original single seal with a pair of SKF /CR9815 seals and you
will be good to go.
For the front cover, remove it carefully so as not to damage the bearings
then reassemble with the slightest amount of sealant between each of the
shims and the cover.
