2013 c250 1.8T while driving 40-50mph i feel slight vibration
Cannot tell if it is a bearing or ? Happens under acceleration.

 

feels like it’s coming from the front?

 

No it is rear or i am wonering if it has anything to do with transmission mount? Driveline

 

Wheel(s) need balancing and/or worn tires?

 

Tires are new wear so far is even no high or low spots on tires

 

Wheel could be bent.

 

Hello!
In addition to already mentioned wheels that need balancing, it is also possible that a prop-shaft flex joint is worn out,. You have one at gearbox end, and another on diff side.
Hope that helps.

 

Thanks, how would i diagnose this scenario? I have 85000 miles on the car. Cheers!

 

Bent wheels is my guess. My dealership lifted the car and observed the bent wheels.
RTW WHEELS (on line) has refurbished wheels for like $150. I bought two and they exceeded my expectations. And no more vibration!

 

will see going to have wheels checked out tomorrow
thanks for the help

 

If it is bent wheels they can tell you. And the place I listed is state of the art. The wheels are OEM and looked like new. I didn’t have high hopes, but was extremely impressed.
