Grease point / nipple on Steering box - what grease ?

[LandRoverGhost]

Hi , I found a grease point / nipple on my GQ 1989 steering box.
(Never had such a luxury on my old Land Rovers ;-) )

What grease should I use and how much - will it spill out somewhere telling me 'enough' ?

Thx.
J.

Can you please post a picture? A smart phone one will do..

Probably not a grease nipple, but more the adjusting grub screw to adjust backlash.
Some rod ends however do require greasing but that's under the box.

Earlier steering boxes had grease nipples.

Earlier steering boxes had grease nipples.
Must have changed about 1990 then as my 91 series one gq didn't have one.
I would have thought greasable would have been better?

What purpose does the grease serve inside the steering box?
What about the steering pump oil(dexIII)?

Without having seen it and the OP saying top I'd assume it's the input shaft?
Maybe it is easier to let the oil lubricate the whole pump instead of seperating it?

Big truck steering boxes have a grease nipple on the output shaft to lubricate the big bearing & acts as a seal , might have been a similar theory ?

This is an old video that explains the typical hydraulic steering system.
I guess in modern systems, or at least in four wheel drives, the whole thing is compacted in the steering box.

And this is a video that explains more modern electric assisted power steering, which I think is a much better system
'cos it reduces "parasitic loss" from constantly turning steering pump.

My old Hoden Barina had electric assisted power steering, but I've never bothered to look more into it back then.
Now, I kinda have some idea.

Yeah, but I'm guessing many "smaller" vehicles like 4WDs don't have grease nipples, 'cos it's not too hard to seal the whole unit with enough grease in it for the life of the box?!!

I don't seem to have a grease nipple in mine(1990 GQ RB30).

That's my guess too. Since the whole unit is a compacted in the steering box(hydraulic and mechanical part of it), it is possible to
to use oil to lubricate the whole thing?
Perhaps, that is the reason I don't seem to have a grease nipple in mine?
Or perhaps the mechanical area of the shaft/cam etc are separated and sealed and greased for life?

mine has a grease nipple on top of the box.(90 ford mav td42) i not sure what grease either but would guess its just a standard bearing grease. should prob check the manual but i'm not at home atm.
