It happens on acceleration when taking off from standing, but sometimes if I accelerate hard in second I can still hear it.
It makes the clunk sound when the car is already in gear and I accelerate, the clunk is also loud and once-off (It only makes the sound once, to replicate the sound I have to step off the gas and then hit it again)
And no it isn’t the lovely normal LR backlash
only under acceleration not deceleration, not in cornering
