Strange vibration issue

[ender2]

I'm dealing with a strange vibration. Here are the facts:

- happens only between 85 - 90 km/h (52-55mph)
- feel it less while accelerating and more while coasting/letting the gas off
- feels more on car's body/floor/seat than on steering wheel
- feel it less when car is cold and outside very cold (> - 10 C), and/or under load (one passenger)
- excluding wheels balancing problem (happens identically with 2 different sets)
- excluding engine mounts (both driver and passenger were replaced), inspected RMM and it seems to be good

Car is 2011, a bit over 100k, 2.0 A/T. Otherwise runs well and it's a really good car.

Any suggestions/ideas are really appreciated.

when is the last time you had an alignment done?

[ender2]

I had an alignment done several months ago (Sep 2017). Everything was in specs.

I get wheel / steering wheel/car vibration in the winter...
Ice and snow in the rims messes up balancing
Only noticeable at certain speeds
Goes away when temp warms up or snow ice melts.

Your CV axles? That is hard to pinpoint. Your ride being an AT seems to me that maybe at a certain,gear,load your engine has a small hesitation

Ball joint maybe, but the alignment guy should have been said something.
