Mechanic (thankfully) is someone I've known for about 8 years (and 3 cars) now, and has proven to be very trustworthy, and reliable. He has checked CV joints, bushes etc. all to no avail in finding a root cause. Hence the testing today which has caused the knocking when steering is on full lock at a standstill. I'm just curious if that could be a likely root cause for the knocking, and general feeling of increased 'bumping' when going over bumps over the last few weeks.
