Replaced my front lower control arms today with the FCP Euro Meyle HD 4 piece kit. The right side was pretty straight forward once I took the brake rotor off and re-positioned the backing plate so I could get a straight shot with my sledge at the knuckle to free the outer joints.
Of all the videos I watched and threads I read, no one mentioned the left side cooling duct that obstructs the bolt from coming out to replace the arm. I had to take the lower panel off and loosen the duct enough to squeeze the bolt past it.
All in all, 7 out of 10 in difficulty. 4 hours start to finish. Shaking from high speed braking seems to be gone.
