I am unable to remove the part without removing the bolts:
Looks like a tough one, don't forget you may be able to cut and replace the bolts. I would try a sledgehammer and a metal rod to knock them loose, maybe let it soak in penetrating oil for a few days if you can spare the time. I've never had luck with heat but I also don't use a real torch. Also, although it would be an insane thing to do, you may be able to remove the lower control arm and the shocks in one piece to get better access to those bolts (aaand the axle looks like it would have to come with it)
Access isn't that bad, just worried about melting the brake hoses. Hitting it with a sledge? I don't have space for a sledgehammer down there lol, but a hammer didn't help much. I will try cleaning them up a bit, use different penetrant, hit it again with impact and heat
But I am looking for options on how to protect from heat
Good luck! I usually let my vehicle sit taken apart wayyy too long when I get to that point. I'm interested in what else is posted, I usually just don't use that much heat because I'm afraid to melt stuff.
