Couple months ago my Peugeot started making “grinding” noise from the gearbox, the noise gets louder and more high pitched when accelerating but it can also be heard when in neutral, when i press the clutch pedal the sound disappears. Both diff bearings and 1of the input shaft bearings were replaced the clutch was replaced as well including the release bearing. But sadly after the first couple of kilometers i started hearing the sound again at first it wasn’t so loud but after around 50 kilometers it was loud as before, any idea what could the problem be ? I am suspecting the other input shaft bearing that wasn’t replaced but the mechanic that checked them before replacing them told me the other bearing was fine.
