    Default Annoying knocking - radiator mount?

    So far replaced the front springs (snapped), top strut mounts, arb-bushes, drop links and the car still knocks when I drive off.

    How would I check if the radiator mounts are broken? Could it be anything else?

    If it's just as you move off, I woun't have thought a radiator mount.

    Check for play in wheel bearings and ball joints

    The ball joints were replaced some time in July last year (17k since) and the noise was present then too. Everything seems to be fine at the wheels.

    I thought worn CV joints clicked when worn? How do I check/know which one is faulty?

    There was a VX technical note on rad mounts. It is possible that they are knocking.
    Now I need a turbo to keep up!

    Check engine mounts as the engine rocks backwards and forwards during acceleration/deceleration.

    Or anything obviously loose in the engine bay.
