Update: turns out getting the STP out wasn't such a big deal anyway. I unbolted the top cover and sucked virtually all of it out with an animal feeding syringe connected to a small diameter rubber hose to get down into all the nooks and crannies at the bottom of the box. Worked perfectly. Thanks again for all the helpful advice, you guys are the best.

Thanks again guys, looks like I'll be sucking out the STP somehow.

STP is not an EP gear oil, it is a viscosity thickener for motor oil. IMHO it is not good for the steering gear box.

I used STP and when it melted and began leaking out, I swithched to John Deere Cornhead Grease. More good advice I got here on this Forum about 6 years ago. Still good advice today.

You may be able to remove the STP from the steering box by using a suction gun. You might want to thin the STP first with kerosene to make it easier to flow into the gun.

Thank you all for the advice. I guess what I was really wondering is if it's okay to leave the STP in there. The box has been resealed with fresh gaskets, sector shaft seal and NOS sector shaft bushings. If there was an easy way to drain the STP out of it without complete disassembly I'd probably go with the lubes you guys recommend. But I understand that if none of you have used STP oil treatment in these boxes you probably can't say one way or the other if it's okay to leave it as it is. Was just wondering, as I tend to do a lot of that where this car is concerned. I've been a car and motorcycle mechanic for most of my life but this stuff from the 30's is all new to me!

If you have rebuilt your steering gear box, then I recommend that you use SAE 140 EP gear oil. JD Cornhead is good for leaky boxes, but yours should be OK with the new seals and gaskets.
