Acura TL Builder

Went to use wife’s mdx 2012 and noticed the awd system making rubbing vibrations and warbling sounds when decreasing speed and making turns while decreasing speed.
Running vibrations felt when driving on highway at 70mph and above.

Sometimes it’s less, sometimes more vibrations. Tried restarting battery. No luck.

Shifts perfect. Smooth on acceleration. Only when cruising and decelerating.

All maintenance done.


Any ideas as to what she damaged with driving in sport mode for so long? Want to keep this vehicle long term.

1) If all of the below checks out?,
2) then maybe move onto the suspension?

I will lift the car and put it in drive, have the missus “drive it”, and see if I can hear where the noise is coming from.

Is it a low mile MDX driven on decent or rough roads?
Just a shot in the dark, if you suspect the vibrations are caused by months of driving in sport mode, find out if there are specific suspension components that are 'dialed in' by the computer when switched to that functionality? The glove box owners manual should give some definition as to what sport mode entails?
You know the drill, look at all those suspension components below that could be loose / worn & potentially cause vibrations.
