Question on Underdrive Pulley Install

I just had this done by a local shop. I think they may have broke the hydraulic motor mount on the passenger side on my 2004 S. The nut was freshly rounded and the motor mount started leaking a lot after a hour or 2 of driving. Shop said they didn't touch the motor mount and to install the pulley they removed the front bumper. I havent seen anything on the internet that says it can be done without raising the engine. Could they have done it without raising the engine? Am I getting a runaround? thanks - btw before the mount went it was pretty sweet upgrade

I have not done it without jacking the engine. This is because the pulley is lower than the engine compartment. I would think they would have had to jack it also.
