The absolutely best penetrant I have ever used (worked where everything else did not, including impact socket and a 6 ft iron pipe for leverage on the hub nuts) is half brake fluid and half auto tranny fluid. I put it in a squeezable mustard bottle with some hose attached. Absolutely miracle stuff.

thats weird, because brake fluid is water soluble...
Aye; that's why I was skeptical when I found out about it. At the time I was willing to try anything to loosen up those huge axle nuts. Once shaken well, it blends nicely. I used DOT3 Valvoline brake fluid and CTC Dexron II tranny juice.

Isn't brake fluid a heavy molecular alcohol? It might be both water and oil soluble? Or not.
I will be trying these on replacing my knackered stub axles this weekend.
