Re: Stp.
I am sure it would. Many people use John Deere cornhead grease which works well in low rpm situations.

Re: Stp.
STP will leak out. Use corn head grease.

Re: Stp.
Just followed the link. Agree with using it in the steering column, but not sure I agree with the guy that is going to use it in his rear axle.

It has been used straight in steering boxes for many years in commercial trucks. It greatly decreases steering effort and prolongs life of the unit. Driving around with a steering box that leaks is the same mentality as having a gas tank or oil pan that leaks. |

Re: Stp.
JD corn head grease has been great in my '32 box. Doesn't leak and when I peaked in after a few months of driving, everything is coated with it. Highly recommend it.

Re: Stp.
The 'late' steering boxes have some very tight clearances in them -49 up and only the correct liquid oils will suffice. We [NW Pacific area] have an expert steering box machinist locally, a V8er too! Newc

Re: Stp.
nothing beats the satisfaction of a correct repair [fix the leak] but in the mean time semi fluid grease will work JDs corn header is just one of many

Re: Stp.
STP will not stop the leaks in an early ford steering box, but might slow it down a little. John Deer corn head grease will fix most of it but there is no substitute for repairing the box properly. I have tried all of these things before. Regards, Kevin.

Re: Stp.
STP is not a lubricant, period. Use a lubricant like corn head grease.

Re: Stp.
That is true.
Ccl4 is not listed as a lubricant either but it works much better than many things listed as "lubricants". All I am saying is, people don't need to follow the herd if they want something better. LOL Last edited by Pete; 10-20-2023 at 09:52 PM. |

Re: Stp.
use 1/2 synthetic grease mixed with 1/2 synthetic trans doping mix up and force into box until it is full drive around and check the level. will not cook off like regular doping and as said before it is like power steering

Re: Stp.
I added a real lip seal to my 32 sector housing. I did not have to cut any metal. I made a paper baffle for the sector bore and filled the cavity with J B Weld. I did have to machine the epoxy for the seal. Never leaked again, I had a thread on the HAMB with pictures.
The seal lets you use the correct oil. |

These were clients that faithfully changed their oil and added that crap (STP). Talk about "snake oil"...

Or affiliated with draglines. ISO 480 and 500 for hoist, drag, and swing transmissions. Consistency of tar when cold-20*.

You’d need to mix it with a grease. I used to work as a General Manager at a speciality aftermarket suspension manufacturer. From the early 80’s until about 2005 they blueprinted Saginaw steering boxes. (think blueprinted engine and you’ll get the concept) The end products had about twice the accuracy of a brand new steering box. At any rate, we used a custom mixed concoction of red synthetic grease and STP out of the blue bottles (V8 formula). Mixed it to be have a molasses-like viscosity. I have a couple of Mustangs with those boxes in them, both of them done in the 80’s. They have a lot of miles on them. There’s literally no play in them. When I rebuilt the box in my F-1 in 2016 I used all nos stuff and new USA-sourced bearings…. the same grease concoction is inside that box. |

Re: Stp.
I have used STP or a Motor Honey type of product in hundreds of vintage vehicles for over fifty years, pretty well solves the oil leaking problem in steering gear boxes.
Of course when STP leaks out it time to repair or replace the gear box.

Re: Stp.
I never add STP to the engine oil in an engine I always use a high quality detergent oil like 20/50 GTX, in recent years I have switched to 10/40 Shell Rotella or Lucas Hot Rod/vintage oil.
Many years ago I had a1953 inboard speed boat that had a 8CM marine flathead eng. The engine dropped a valve one day that broke a piston. I was able to pickup a complete 8CM that a friend of mine had. When I stripped my engine down, removing all of the marine equipment to put on the replacement engine I noted what appeared to be a blatter out of a football laying in the bottom of the pan, When I tried to pickup 'the glob', I found it to be a large gooy mess. I normally changed the oil once a year at the end of the boating season, the crankcase held 5 quarts with the filter. When I cleaned the 'glob of goo' out of the pan it held seven quarts...

Re: Stp.
In the early 70's, if you ran an STP decal at a NHRA national meet, you got some $$ and a case of snake oil. I asked my buddy (who drove for a factory team) what he did with the STP...... he said it made a reasonable rust inhibitor BUT dont use it on a cast surface (like a bare block) because you cannot wipe it off.
