Problem: upper spindle bolt secized to the lower control arm. in atempts to loosen it broke off the head of the bolt leaving me with a stud. so far ive tryed 2 days of soaking in LW and WD40, loads of heat with a propane tourch and im trying to drill it out but all my drill bits suck and will not bite into the forged steel. Is there awnythign else i can try? i have basic tools.
