You don't have to remove the bumper, but you may have to remove both fenders. You might not have to if you have enough clearance to get the support out. Remove headlight assemblies, grille and body panel under those. Remove battery and battery tray. Remove radiator and evaporator (have the a/c system discharged). There's other small miscellaneous bracketry to remove. Remove support mount bolts and remove the support.
Just an FYI, my core support bolts aren't holding anything. The nose just kinda floats there.
