how about this...i need to replace the pitman arm on my '94 c1500 pickup. the nut on the sector shaft has been there since the truck rolled off the line in '93 and is, of course, stuck pretty securely. i was going to apply heat to the nut and expand it, but what about applying dry ice to the sector shaft instead? i know the nut would get cold, too, but maybe not at the same rate, if their compositions are slightly different. i just know that if i go at the thing with a breaker bar (can't find a 1-5/16" socket in 1/2" drive, anyway) i'll break something. i have a bad habit of snapping stuff.
On my dually chevy I could not get it off to replace the p/s box I was able to take the whole unit off and put it in my 12 ton press with split type bearing separator and it pop off with a big bang not sure I would of gotten it off any other way. as a matter of fact I was unable up to that point with my other attemps.
