Please Help What Put Inside: Grease Or Oil

This is the housing of the wheel system. I have opened the nut above and it seems that there is grease inside, but this hole is made for oil, and I have read that inside we pour oil for gearbox SAE 80.
What must I pour inside?

 

Oil can leak out, so grease is sometimes put in. That what I did. It worked fine for me.

 

I see the idea. It seemed to me that thre was some grease inside, but oil can be transformed in grease for various reasons.
And grease in oil ? By the way, what is the name of this part? pitman housing? In French is is a "boîtier de direction". I don't find the equivalent.

 

Ross steering box . I would use grease too

 

Steering gear. Also sometimes called a steering box or steering gearbox, but "steering gear" is what Jeep calls it. Steering box is a more literal translation of boîtier de direction (boîtier == case, housing, which is close to box).

 

Yep, mine wore like crazy.. Use oil..

 

I use knuckle pudding. But my box is shot anyway.

 

How do you get oil through a grease fitting? When i rebuilt mine, i just used grease...for you oil users...what type/weight oil?

 

What grease fitting? The factory used a pipe plug which you can get oil thru with a bottle with a spray or hand pump and hose.

 

@jeepstar Grease fittings are removable if that's what you have on yours.

 

Looking now... I have a plug fitting. If I recall, I hand packed it full of grease before I sealed it up

 

Thanks for infos. I understand that there are 2 schools. Oil is better to lube moving parts, grease is for other purpose but I understand the 2 possibilities. I added some oil SAE 80 and I'll look at leaks.

 

I got a half used can of relative bearing grease I was hoping to use...

Seriously though, I'm watching this one closely for the best answer.

OEM calls for 90W I think.. Once I rebuilt my box I ran 140W.. Worked great..

 

Use this: John Deere Special-Purpose Corn Head Gun Grease - AN102562
Used it when I rebuilt my Corvair box, it would make a good knuckle filler too...

 

I added some oil 80 SAE and it seems smoother, no leak. I believe that grease sticks to the walls of the box but oil goes where it must act.
Mayb we can have a mix of oil and grease?

 

You can try this: STEERING BOX LUBE. Good luck getting it though.
