Sounds like something knocking/clicking constantly, sounds like cv joint but clicking noise is constant, worse under load, doesnt make any difference if car is on a lock. Could this be inner CV joint?
Any feedback will be much appreciated!

It could be diff bearings mate, If you get inderneath the and grab hold of the inner cv joints, try and move them up and down, there should be no play in them att all where they enter the gearbox, If there is its most probabally the diff bearings,

Hope that helps
