    Thats a good question mate
    No I have not had the gearbox oil checked
    I’ve got it booked in next week for gearbox oil check

    Hi guys.
    If my Drive shaft or CV joint was nackered would the knocking noise be there all the time ???
    And would it have any thing to do with going away when I put the clutch down .
    The noise is deffo coming from the drivers side front.
    Iv taken it to a garage quite a few times now but there is no noise when I go to the garage.
    I need to know if I should be looking to spend money on the shaft cv joint etc or the gearbox ??

    Driver's side front would tend to exclude gearbox.

    Thats what I was thinking it can’t be gear box
    All the gear changes are smooth No crunching or Stiff gears etc.
    Selects all gears very nice and smooth

    Hi guys
    I took my car to a good garage today the mechanic drove the car whilst it was making noise.
    He then put it on the Ramp and did some good looking around.
    He found that the Wishbone bushes are badly worn with loads of play in there.
    The gear box looks in good dry condition with no leaks The Driveshaft & CV joint also look good.
    So I’ve decided to change both the Wishbone’s on the car.
    Would anyone know if the Jetta came with Aluminium bush’s on the arm ??
    Thanks
