Thudding when letting off the throttle?

[schmergal]

Hello folks, getting a heavy thudding noise when let off the throttle suddenly, put up on ramps and can feel some play when turning the inner cv joints, anyone had this issue? Any help would be appreciated, was told they can be pricey, just hope it's not the gearbox

Thanks in advance

Check your dogbone mount, this is what it is on my S3. Clonks when changng gears, hard acceleating.
