Engine mounts?

Bringing my car into the dealer for what we think is a bad wheel bearing tomorrow. I have brought up in the past a rough idle at start and they've found nothing. I trust my dealer master tech very much but I've never asked to have the motor mounts checked, I just know he checked for any engine codes, misfires and bad coils etc when I brought it up before.



Doing some reading tonight it seems like an enhanced shake or vibration at idle and/or vibrating shifter could be correlated to fail(ed)(ing) motor mount or sheared bolts.



Truth? Chances?
