So to start, both nuts and probably bolts for the front end lower control arms are stuck, which I've learned is a common issue. Tried heating, 750ft lb impact, penetrant, nothing worked, so I decided i need to cut it.

Went to remove the brake caliper to have room to get in with a sawsall and both bolts holding it on are stuck. I don't think i should heat it because it's aluminum. This is the first mod I've tried doing to my g and it seems it may be over my head.

I'm looking for advice to get the bolts attaching the caliper to the knuckle, or should i just give up and take it to a mechanic? its pretty disheartening when 1/2 of the nuts are stuck, these aren't even the only ones

 

Update: I got all of them after applying penetrant, torching it, and torquing the **** out of it daily. But now the stud that goes into the knuckle connecting the lower arm snapped. Lol

 

The bolt that goes into the knuckle connecting the lower arm should be something you can replace? Why are you replacing the lower arm[s]? Bad ball joints?

 

I think i can, I just bought a bolt extractor bc the head snapped off. I was installing coil overs. I think this is a dead thread now I may delete it if I can, thanks for asking though
