Hello this is my first post. I have just bought a used 2003 x5 3.0i and noticed when going slow over uneven surface there is a faint knocking sound from front left wheel. I looked over a few forums and it seemed quite a common fault with people saying its either the anti roll sway bar link, anti-roll bushes or steering control arms. Just wanted to ask if anyone could advise how I can check for each of these without first going to a garage? Many thanks in advance
