parts for the front steering pedistal are hard to come by... you pretty much have to take them out and get them matched up at a seal / bearing house by ID, OD and thickness.
the steering box seals, as far as I know are available.. it's only a side cover gasket and a sector seal anyway.
as for the grease.. it's likely a better way to go anyway, if your steering is tight and you only have a seep.
I have tacked to my wall, a ford service bulletin dated 10-31-1962 stating to use 0# grease int he steering boxes.
In a 950 nf I just rebuilt, I had a hard time with the lower seal on the 1 piece pedistal, the steeirng axle shaft that protudes down had wear on it and I could not sleave it.. so I packet it with 0# grease, as it would weep 85/140 gear oil.
the grease packing stopped the weeping.
NLGI 0# and 00# grease is available at good fuel / lube distribuitors, or you can order it.
Many JD delers stock cornhead grease tubes.. AFAIK it is 0# or 00# grease and will work well.
it slowly slumps to fill in gear boxes, j=yet is thick wnough to not weep..
the steering box will take 2 tubes or so to fill the box and stering column, the front pedistal on a 2 piece will likely take 3 tubes or so. the front pediastal on a 1 piece is hungry

and takes about 6 tubes if empty..
you will end up with strong arms if you manually pump it in... if you have an air or electric grease gun.. no problem.
if manually doing it.. save some elbow wear and remove the front pedistal cover after removing the grill, and just use your grease gun with only the tube and plunger to manual force the tubes into the cavity.. fill to the top, then repalce the cover.. clean the gasket surfaces and use rtv or right stuff..
ont he steering box, add a 3/8 zerk to a pipe bushing in place of the fill plug and pump in there...
ps.. regular gun grease like #2 or #4 is too stiff and will leave a cavity. In a pinch i have used 8oz of 85/140 or hub oil, and a tube of #2 to get the same results in a clapped out old mower gearbox, letting the gears mix the grease and oil into a nice thick soup that won't leak past a worn seal.... but it's much less hit or miss by just getting the 0# or 00# grease from the get go..
