anyone out there know how to take the hardness out of a bolt
I have several control arm bolts seized into the sleeve/bushings and will have to use a sawzall to cut them out - problem is they are Grade 8 hardness and eat sawzall blades like no tomorrow
is there something I can do on the car to remove some or all of the hardness? ie some form of heating and or cooling
in the alternative - does anyone make like a cobalt sawzall blade?
this may seem funny but as an experiment it may or may not have an effect
I've been told not to acid tank hardened parts like spindles as it removes the hardening
I've used liquid drain cleaner to clean rust from parts in the past one thing I learned doing this to a hood latch is to never put liquid drain cleaner on springs as it makes them brittle as hell , such that they break when you try to use them
so maybe a little liquid drain cleaner in a spritz bottle ??
at least any rust around the bolts will be gone - don't forget to rinse

If you heat as red as you can and let it cool slowly it will remove some temper, (works for females also). Why not torch them off?
If that was a 2015 chevy you would have to replace the whole "chinese" car.

Drain cleaner is caustic (sodium hydroxide) and will not remove rust. Acids could cause hydrogen inclusion which is why you shouldn't chrome springs. Acids do not affect the hardness.
how about cut off wheels for your die grinder,,, if you can't get the straight die grinder in there how about a 90 degree die grinder,,, I think the discs are 2 or 3 inches in diameter
heating them up worked wonders - only took ten minutes per cut and only burned up 3 blades for four cuts vs 15 blades for the first two bolts that were no heated - cutting really slow speed also helped I think
four more to do and done
