Default Re: Metal hardening

If your factory made socket (even ground down) feels like it will break, your shock arm is rusted tight. Heat it red, let it cool and spray with real penetrating oil like PB Blaster (don't waste time with worthless WD-40). If still won't budge, heat the outer edge red again and try turning while hot. Check ebay for sockets, too.
