    Engine/Gearbox mounts
    Exhaust rubbers - check for free play in the exhaust the rubbers, mountings & conponents (ie) heat shield.
    All steering & suspension wishbone conponents if it's feels the nocking noises comes through the steering wheel.

    I have a nocking noise also when moving mine turnt out to be bottom ball joint. Don't always feel it through the steering. Could be anything from top donut to wishbones to anything tiny like a bolt :-( I hope you find the problem soon, let us know if u find it.

    My partner whos a mechanic said - hows your brakes? They could be stuck on to cause the nocking noise
