Default torque tube

I have a 2002 coupe,auto.trans. The driveshaft is making noise. Any idea what I can expect to pay? Thanks!

depends what's wrong with it... you could expect to pay at least $800-1000 in labor plus whatever the parts cost that need to be replaced

Less than that for the TT. I paid a corvette shop $1000 to install a new clutch, trans and rebuilt the TT.

Sounds like you got a good deal.

I'm in Waco and don't have many choices. The only place I know of is the Chevy dealership. I may have to use them. I guess I could try the Dallas area.

I had a hard time finding any shops around me that would service the torque tube. The Chevy dealer would only replace the whole thing at a ridiculous cost, said it was "non-serviceable". Our local driveline "specialist" wouldn't touch it either.

So I disassembled the tube, created some simple instructions based off the Service Manual and went to NAPA. They said no problem, and pressed in some new bearings for less than $100 shop labor. The couplers are the other wear items, and they're easy to change with the right socket (Torx Plus 45IP).

the labor should be pretty much the same because the whole rear still has to come out to get the torque tube out

if you were closer I'd give you a hand... it really isn't that bad of a job if you're mechanically inclined and have the required tools... there are plenty of LS specific shops in the Dallas area if you decide to bring the car this way

What all has to be removed to remove the torque tube? I have tried Bing & Youtube with no luck. If you know a site that has this info please let me know. Thank you!

Here's a basic list of things I remove.

pull brake calipers, like you are changing the pads
pop the tie rod so you can remove ebrake cables
support rear suspension to remove upper shock bolts, upper control arm bolts
pop axles from the diff, to navigate lowering past the brake lines
exhaust mid pipe
tunnel plate
shifter cable at trans
clamp from input shaft in bellhousing
torque tube bolts to bellhousing

start lowering the rear, remove wire clips and brake lines that are attached as you go
eventually end up with something like this:

That is EXACTLY how I did my drivetrain maintenance. When I reinstalled mine, I installed JUST the TT and then assembled the trans/diff onto the TT. Makes the single person reinstall a LOT easier..

If you have a place to work on your car, get the tools and GETERDONE!

So, are there any symptoms of needed overhaul and are the effects gradual or sudden?

I am asking because my 2002 MN6 has 148K, not really been hammered on and no noise or vibration.

The bearings will just start to make noise. When they start to make noise, you need to change them because if the front bearing fails, it will destroy the clutch pilot bearing.

The couplers will deteriorate over time. The rubber cracks. Inside the rubber is a special very heavy duty fabric chord that allows thee rubber to flex and not deform and stay in shape over prolong engine loading.

When the rubber breaks down to the point that it no longer works to keep the inner core supported, it will deform enough and start causing drive line vibrations. There comes a point in time that the chords get destroyed and you get LOTS OF NOISE and sometimes TT damage.

I disassembled my 02 Z TT and everything looked 100% and sounded solid when rotated. Back together she went!






My buddys 2000 A4 Coupe had some heavily cracked couplers. He was at 100,000 miles.

This is my driveshaft with worn out bearings, out of a 2003 corvette z06 that had 58k miles at the time. After I installed the new bearings their was zero noise.
The bearings I installed were
One SKF 6007 2RSJEM
Two SKF 6008 2RSJEM
and two driveshaft shop couplers(guibos).
5k miles later with much spirited driving no noise, no vibrations, just smooth.

When you have everything out TT, transmission, etc. Go over everything and make sure everything is fine you do not want to pull out the transmission twice like I did.

Noise is the first sign of worn out bearings. I had a slight vibration on mine at the time. Vibrations happen from neglecting to replace the bearings once they are worn out. Worn out bearings put stress on the ends of the driveshaft, prop shaft, end shaft which then cause the vibrations, they can become damaged permanently. Then again that was what I was told by the corvette shop who rebuilt my driveshaft. After I installed everything back together everything was back to being smooth.
