Technical Steering box lube?

I'm in the process of rebuilding my saginaw 525 manual box and my old Motors says "medium all purpose grease". Does anyone have something more specific? Thanks

 

This?

I put 90 weight rear end lube in mine, it became much smoother and easier to steer.

 

I was wondering about using heavy gear lube. fred , that's the grease I would use if I use grease. I was thinking that grease might not get into the ball/screw ***embly.

 

Have you seen what the factory grease looks like? This is what some use. I get what you're saying. What I'm saying is ignore what you THINK and use what OEM's KNOW. It must work, otherwise they wouldn't use it. Those college guys get paid large to know what works. I trust most of them.

 

Penrite steering gear lube

Yip this is the gear I use, its good stuff..

 

have heard STP is good, haven't tried it.

 

I read that on the Barn and when I re-sealed my '39 box I used it. Seems to work good.

 

I put a grease ****** in my Corvair box, so I could pump fresh grease through occasionally. It was designed for oil but it would leak out now....

 

Every box I have is filled with John Deere corn head grease. love it. No leaks.

 

There's a new Tractor Supply store opening in town. First thing I'm gonna do when they open is see if they have corn head grease.

Gear oil is too liquid. Normal (NGLI #2) grease is not liquid enough, it doesn't flow. You need a #0 grease.

GM "Approved Steering Gear Lubricant" is P/N 1052182. It comes in a large plastic tube that you squeeze into the steering box like toothpaste. It is certainly thicker than gear-oil, but it is nothing like grease. Pretty easy to use.

Unfortunately, GM has discontinued it some time back. But there may be residual stock around. I located some in 2004 by calling parts departments of Chevy dealers around the country. Found some at a dealer in MA and they shipped four tubes to me.

 

Thanks for all the input. I'll probably go with the grease, but I' m checking out a couple of gear oils.

 

try Yoder Oil in Elkhart I used to deliver oil and grease to them , they might have what your looking for .

 

What about CV joints grease ( Moly type - grey colour). It should be fine i think.

 

I make my own concoction; I mix moly axle grease with just enuf rear end 90W to make an almost liquid mixture.

 

John Deere corn head grease is the stuff to use. It acts like a solid when not being moved. So it doesn’t leak out when your car is sitting. But turns into a liquid when moved, like when you turn the steering wheel.

 

Link didn’t work, but Tractor Supply has Cotton Picker Spindle Grease. It is “00”. Same specs as PennRite, but doesn’t have a cl***ic car on bottle so it is only $5.99 a quart rather than $20-22.

 

HA HA Totally missed that.

 

use what the people who designed the box said to use sae 90

 

Still a valid question that seems to pop up every few months. Corn Head grease is always the right answer!

 

Except the ratings have changed over the years. There was a great thread on this a few years back. I will see if I can dig it up and dust it off.

 

My go-to is Penrite Cl***ic Oil Semi Fluid Grease Steering Box Lube. Stopped my stock model A box leaking!

 

I used 250 weight gear oil to start but before I even seriously drove the car, I found the sector shaft seal wouldn't hold it. IIRC I asked Borgeson what they use. I believe, at that time, they would rebuild GM boxes. This was at the show in Louisville and one of the people said that they thought a grease was used.
2020,I think it was, I drilled a bolt to replace one of the top cover bolts and added a grease zerk to the bolt. I used a medium bearing grease to supplement the oil (however much was left).
At this time ,I'm planning on getting a new 24:1 525 from Borgeson. I don't actually know that my box is bad, but the new one should make the car steer easier.

 

I plan on using the Corn head grease on my 41 p/u stock steering box rebuild. In the recirculating ball-screw in the modern boxes, I wasn't sure the grease would adequately lubricate the ball screw.

 

The guys that ran vintage British cars with lever shocks ran STP.

 

That's the problem, in a nutshell. The "viscosity" of grease is called the Grade Number. Most grease is Grade #2, which is too thick to flow. The grease you want is Grade #0 or #00, which will flow, but not run out like gear oil.
