Torque Tube Bearing

The Precious has a buzz coming from the "clutch area" when it's cold.

With the clutch out, in neutral, buzz with the rpm.

With the clutch out, in gear, buzz with speed.

With the clutch in, in neutral, no buzz.

With the clutch in, in gear, buzzes with the speed.

Following this page:  It's an input shaft bearing.  There's, in effect, four of them on a C6.

One at the input end of the torque tube, two at the output end and one at the input side of the transmission.

The sound appears to be coming from the front bearing.

Unfortunately, it requires nearly all the steps to change the clutch to get at the damn things.

I can't find a reliable listing for the parts I need either.  I hate asking the dealer for part numbers.

      Here we go again!
      Same old shit again!
      Drop the trans and torque tube.
      Take up the ass without lube!

      You left your left...

      They're nearly always cheaper to fix than replace. Especially when it's got the sentimental value of your mom, on her death-bed, saying, "I saved and saved and never had any fun with it because I was going to retire and THEN have fun. I've been retired a year. Take the money and get something FUN!"

      A Civic or a Focus... I'd have replaced that shit. The Precious? As long as it's fixable, I'm fixing her.

      Now that I've done this irritating rear drop once, it's not near as intimidating. Still irritating and not made better by not going ahead and doing the torque tube while I had it out for the clutch.

      OK, understand now.

    I did the equivalent job on a Porsche 928 recently.

    Same-same really, I suspect. In my case, remove the exhaust to remove the rear suspension to remove the rear-mount transaxle to remove the torque converter to remove the torque tube to remove the faulty bearing to install the new bearing. As the manual says, reassembly is the reverse.

    If there are other bearings in the path as you say, I would be considering replacing those at the same time.
    On the 928 that meant $50 worth of torque converter and gearbox input bearings and a $20 set of seals for the gearbox to avoid having to do the same job in the near future.

    Good luck!

      I think I will be doing the axle seals while it's out.
