    Gearbox input shaft bearing noise ?

    Getting slight noise when clutch is out but dissapears as soon as clutch is depressed. Is this needing urgent attention or can I run the car indefinatly and sort it when and if the clutch ever needs doing.

    Frank, depends on how noisy. Mine has been noisier with the clutch out for most of the 11 years I’ve owned it. Will rectify it if and when the gearbox has to come out, but would suggest if yours is not too excessive, then leave well alone.

      Frank. Ditto with Ian. I have had a noisy input shaft bearing for longer than I can remember. It started not long after the gearbox was rebuilt, but hasn't got any worse since then. I would leave it until it becomes worse. It is a very robust bit of kit, and highly unlikely to fail.

          I have just rebuilt a box that had this problem, but it was really the knackered synchro rings that needed doing.

          This time I paid extra for the proper quality bearings, as one I did a few years ago that was previously fitted to the car was also starting to get noisy.

          Some years ago I was talking to EJ Ward at a show, and he said they had tried using the cheap bearings and had both the first two boxes back with noisy input shaft bearings within 3000 miles. This cost them a lot of time money and needless to say they were not going to do it again!

              Sorry, tagged but posted accidentally.
              Thanks for all your replies. It's not really that bad and now feel happier just to leave till something more serious arises with the box. Out of interest, it was rebuilt about ten years ago so maybe it had the suspect bearing fitted.
