Cant remove hub end caps

Seem the hub bearing on my Cobalt 3 front wheel is knackered, but for the life of me I can't remove the end caps. Crank Brothers say wrap pliers in duct tape and pull them off. I have tried this and tried mole grips, i have scratched it up a bit despite their duct tape idea, and I can't get the caps off even a smidge.
Any ideas please?
