My corsa keeps getting a knocking sound on full lock. I understand this will be the CV joint? However, it doesnt do it all the time which is confusing me. I was in a car park which was empty, went on full lock several times and didn't hear a peep, yet after half an hours driving i turned the car round and it started knocking?
I didn't have any problems with knocking on my corsa, but within 6months, both my CV gaiters had dislodged themselves (there was a rubber bit holding each side on to the wheel, dad did show me but I'm not good as explaining, 1st was noticed at an MOT, the second when dad serviced it) anyway the rubber was all hard and brittle (05 corsa) and this happened on both sides. This could be your problem...
