Hi there just recently ive had a loud knocking noise coming from the front of the car only when its in any gear if its in neutral no noise if u rev it no noise even.rolling along road in neutral no noise but as u get faster in any gear knocking noise appears plus when u slow down there is a swirling rumbling noise and no knocking but once u acclerate again the knocking noise is back any ideas if its the gearbox? Ive looked at the driveshafts and cv joints theres no leaks at all no warning lights are on either any help id be greatful for
