Recently I have been noticing a noise coming from my drivetrain. It is most noticeable in the lower gears but I can hear it in all gears. It almost sounds like a scraping or rubbing sound. It goes away when I enguage the clutch or if I put the car in neutral while driving and I let the clutch out. Any ideas what this could be? Throw out bearing? Synchros?

Thanks,

Charley

Yes but it's not. We changed it twice. Now we think tranny of torque tube.

diff for sure.. if you notice it dosnt matter what gear you are it the whine is consistent with the over all wheel speed in your video ,,the other thing that shows me its the diff is that it only make the whine when you are under a load not when you are coasting... its the diff for sure

check you rear end gear lash .. on the ring and pinion or the ring and pinion have gone bad...

Just to be clear, the OP posts a question.

Then Bossv8 finds a video & asks the OP if it sounds like this.

So the video is not, at this point, necessarily what the OP has.

We need the OP back to confirm or not if it sounds like that.

sorry i thought it was a video of the OP car...

BossV8

My fault. I am sorry for the OP. I hijacked his post without wanting.

No the sound mine is making is quieter than that. Also mine seems to varry by engine speed where yours seems to varry by vehicle speed. I tried videoing mine but the noise wasn't loud enough to be heard.
