2012 S60 T6 clicks when put into drive

[cbutler]

I've got a weird issue with my S60 and am wondering if anyone has ideas as I've stumped the folks at the local dealership. When the car is put in park and turned off then restarted, after it comes out of park and you release the brake, there's an audible click that seems to come from somewhere in front of the driver and you can "feel" the click in the gas pedal. It only happens once and within the first 3 feet of motion. It's almost as if someone is plucking a guitar string without the reverberation. If you just stop the car and put it in park, then back to drive, the problem never happens. Also never happens once the car is moving including after stopping at traffic lights.

Would appreciate any ideas! Thanks!

I had a click from reverse to drive first time in the morning after axles were replaced by Volvo. They put lock tight where the axle goes through the wheel bearing on both sides and the click has never returned.
