See, you two can be nice![]()
Does it stop when you apply the brakes? - could be loose pads/retainers
As RH says CV joint ... pull the driveshaft take it round the bock see if the noise has gone ... don't leave a dodgy CV joint, they 'let go' quickly ...
you cant just "pull a drive shaft " on the front requires stub axle removing ,cv would be worse in lock ,but does sound like pad retainers is a good start
300tdi in first post ,and pad retainer is common with them ,though more info gives better diagnosis
