Hi, just picked my ‘11 TDV8 which I imported and noticed a humming/drone noise similar to the noise an aggressive off-road tires makes. This happens when I accelerate the car past 40 mph, and increases by speed, also notice that the sounds stops completely when I lift off the gas pedal, and starts again when I press again.

Do you guys know what may be happening ?

Transmission and acceleration seems good and strong.

Also noticed some play in the front tires in off road or when coming over a tall stop bump

Thanks !
