I don't know what it is with Jersey dealership but they are the worst.
I have my own case open against a dealer in Hackensack and Customer Service found in my favor and they still fighting tooth and nail to make things right months later
Hang in there
I torqued them down while it was up in the air
If the car seem lopsided then loosen up the rear bolts while on a alignment machine since you'll need the weight of the car on the suspension to level it off.
I added a 10" powered Rockford Fosgate subwoofer to my premium.
They go for $170 on Amazon
If you want to listen to it before making the choice I'm in North Jersey also
Not the one in Hackensack for me
You can check a thread I started under issues/repairs
Ford found in my favor of issues with workmanship and they still don't want to comply
