Saxo VTR 1.6 wheel knocking (left)?

when i drive aboce 30mph the left wheel starts to make a lous knockinh noice, it can be felt when you place your foot on the floor in the left seat,

ive been reading up and some people say it may be the Cv join(worn) but it only started making this noise when i got it back fom the garage after having the hub and nuts replaced.

To get it back to that garage is 120 miles away (2 hours drive), Is it safe to drive the car to that garage with this knocking sound anyone?
