Steering box lube

My '56 steering box is in decent shape other than the fact that it leaks the 90/140w gear oil I use. It's actually an F-600 box, but it's essentially the same as the F-100 box, just a little bigger. I could remove it and re-seal if I could fine the parts, but am considering adding a zerk to the fill plug and just filling it with chassis grease of some flavor. Is this good practice? I have always assumed that gear oil would be more effective at lubing these things compared to grease which in my mind might get pushed away from the sector/worm interface. Opinions?

I too recently put a F350-600 steering box on my F100. Thanks to many discussions here in FTE I filled it 00 Corn Head grease. I bought it at Tractor Supply . It's thick enough no leak but not too thick like grease.

You are correct about grease being pushed away from gear surfaces.

I haven't driven my truck enough to give a great testimonial but everyone here says this stuff is perfect.

I hobbled out to the garage to take a picture of my used bottle. I used about ¾ of the bottle.

If I hadn't taken an unscheduled nap during Truckstock (Never lie down "just for a minute" in the middle of the day.) I would like to have driven your truck. Does the bigger truck steering box make a big difference? I'd like to improve my steerability without adding power or rack and pinion.

Yes, it makes a lot of difference. You saw my driveway and garage, Ken. I can back my truck up the alley and turn into the driveway and turn again into the garage with only my left hand on the wheel and my right arm on the seat back as I look out the back window.

Thanks guys, and yes, like Abe, the bigger box does work better. I wouldn't say it's a night and day difference, but it's definitely easier to steer and has much better on center feel. As far as the proper lube goes, I guess the trick is to find some kind of lube (maybe like Lucas?) which is just thick and sticky. Looks like the stuff that Abe showed would work. Or this stuff? https://www.ebay.com/itm/333150463277

The Ford Barn gang really likes the John Deere corn head grease for steering boxes. It has worked well for me on a steering box and torque tube connections.

Here's my driveway and garage that I back into one handed. And usually my daily driver Tacoma is parked in the space next to the house.

The corn head grease is in a cartridge? I'd need a zerk?

Just pull the plug and put the grease gun in the hole. The corn head grease is pliable enough to flow in.

You don't need a zerk. The 00 grease I used is in a plastic bottle that you simply squeezed into the steering box until the box is full.

I supplied both steering boxes to Abe and Steve. Steve is correct it's not Power Steering but a marked improvement. If I sell a truck I always swap in a larger box as 98% of the f100 boxes are shot. Plus I need the f100 boxes for cores.

As an aside, the corn head grease is “0”
