  2. Found out what the steering knock was

    Alfa 159, Brera & 946 Spider
    Got some time to investigatetoday. I Thought it was blown out bushes on the lower wishbone, or a buggered rack, but it was just a loose steering rack bolt!! It’s a common problem apparently!? The knock from left to right is gone now, I’ve felt it flopping around for a while now, when i...
