Strange Noise??

This week my car developed an annoying knocking from the front passenger wheel and on a 400 mile round trip then developed a terrible noise from the front of the car at about 70mph.

Car was dropped in to local dealer and found to have a loose droplink (?). This was fixed under warranty but in driving the car today the noise remains.:rotz:

Now, i took it to 80 and disengaged the engine (just in case it was engine noise) but the noise remained.... it's defo a new noise and i wouldnt say it was wind related.... so....

has this droplink thingy possible caused any damage or is it something else. (and yes, car is booked in for monday)
