Ok guys i know this has probably been covered elsewhere but just need to pick your brains.When i turn on full lock i get what i would describe as a knocking noise.The car drives fine no noises whatsoever it only happens on full lock.Anyway the reason i ask is the car is going into my mates garage next Saturday and i am hoping it is nothing too major (costly) i'll be happy if is cv joints.What do you think.2004 TD4.Thanks.
