When last had my spider serviced, about 300 miles ago (very approx) chap said was good example but had few things which will need looking in future, one of these was front wishbone drivers side, anyway kinda forgot about it. Now its knocking badly, i'm still driving it to work, im getting this booked in to be fixed but won't be till next week maybe 2 weeks!! should i not drive it? or unlike rear bushes thing can i drive with knocking untill it's replaced, and am i risking killing myself or others if i drive with knocking? i.e. is my wheel gonna fall off??
