  • The sweet sound of metal grinding!

    First let me say hello to everyone. It has been a long time since I have been here and am glad to be back.

    Now to my current issue. My bird's has been singing a different tune as of late. When and only when accelerating from a complete stop where I bring the rpm's above 1500 I get the sound of grinding, though not like gear on gear grinding. To me it sounds more like a bearing that is bad. You know the sound, and it's not quiet. When it happens I am typically at an intersection and it get's the attention of all those around. The sound makes me picture a disc spinning on a bad bearing that causes a wobble. Like a bad wheel bearing but not that deep and spinning at 1500+ rpms. By the time the clutch is totally enaged/pedal released the noise is gone. I can reproduce the sound in 2nd and 3rd though I really have to try for it, ecspeically in 3rd. This leads me to believe it is nothing to do with the gears.

    Initially I was thinking my clutch or or throw out bearing. Though after reading my manual I haven't seen the mention of a throw out bearing. I am not experienceing any slipping at all.

    No matter what I will be fixing this myself though I am certain someone here must have experienced this before me.

    I am at 126,000 miles and had a new clutch in around 75,000.

    Let's see some thoughts and thanks in advance.

    sounds kinda like a problem i have, i took it to a transmission place and said it was just from the shifter and the vibration. although your situation sounds a little different then mine.

      My first thought was the throw out bearing. Put it up on jack stands, pull the clutch fork out and see if the noise goes away.

        ok

        Thanks for the replies. I think it has to be more than the shifter and vibration though i would love to be wrong.
