I've had an annoying knock from the front of my car for a little while now so I decided to have a look at the causes. Lower Arms - Nope, bushes seem fine Drop Links - Nope, all ok Bottom Ball Joints - Not them ARB Bushes - possible although they look like they've been changed Top Mounts .....ahhhh. Rubbers appeared ok, changed the brearings, put some H&R springs on, put it all back together and no more knocking noise.........UNTIL TODAY!!!!!!! AAAARRRRGGGGGHHHHHHHHH!!!! * Note to Voorhees......No Swearing!!!
