'14 aero noises
 

Hello all, new here.
I have a 2014 Aero, completely stock. 52k miles
i started noticing a loud vibrating / grining noise about a month ago, it has only gotten worse.
It happens when i come to a complete stop, or when i take of from the stop, and sometimes when it is shifting from 1st to 2nd gear, sounds like it is coming from the transmission side of the engine bay

It also sounds like i can hear the exhaust in the dash when i am accelerating as if i were getting on the highway, around the 3k to 3.5k rpm range

last question, when i am backing up, and turning the wheel at the same time, the whole front end wobbles.

any ideas as to what to check before i go pay dodge to fix it???
TIA
