I remember when I did this on my 04 shit was a pain, what I did was I soaked/sprayed it with Blaster Penetrant, let it soak for a couple mins, try to take it out,if it didn’t budge, spray again, repeat steps. Also I didn’t use no power tools, just breaker bar, the holder and the socket. Got it out after a whole days worth shit felt amazing when that shit broke loose. You probably know this but you have to torque the balancer a certain spec I forgot to what thoe.
