I hope you got a service ticket that explains they replaced the bolts.
Take it back one more time and have the service manager go for a ride with you.
When he feels the vibration simply state it wasn't there before, I want it made right, without cost.
Then tell him he will go for a ride with you after to make sure it is right.
That isn't so unreasonable.
