Clacking Noise in Torque Tube

Clacking Noise in Torque Tube
Several days ago I began hearing a clacking, metal to metal noise.
It would happen in the lower gears when the Car is generating that
Intial thrust. It would also sometimes happen during certain car jerking
movements. But under normal driving conditions, the noise does not occur
I had a local tech, who I somewhat trust, through the use of Sound detecting equipment and headphones determine that its definietly coming from within the Tube assembly (running from the engine all the way to the tranny.)
He feels a bolt has come loose and in certain thrust conditions, it is making contact with something. But he also has conveyed the possibility of damage where new tube assembly ($2k!!!) would be rEquired
Anyone ever have this happen?

These are the "star" bushings that sit on either end of the driveshaft, that carry the power from the clutch to the driveshaft, and the driveshaft to the transmission input. Ekler sells a nice solid aluminum replacement part if you don't want to go through this a second time down the road. High HP will cause them to fail before their time, but I suppose enough hard launches w/ a stock motor will eventually come to the same conclusion.
First of all thank you for posting your answer. I haven't received many responses about this issue and being that a new C5 TQ assembly unit costs $2400, I'm sure you can understand my anxiety over it.
Only certainty so far is the noise is coming from the tube. Possiblities are:
1. Loose Bolt with no damage to housing
2. Loose bolt with damage to housing requiring a rebuild or brand new assembly unit
3. TQ Tube bushing failure.
Any other possibiities?
I was given 5.8 RR hours from the dealership (I guess that appies to whatever the problem is within the tube). Of course that doesn't include parts. If you are right, how much are the bushings? I'll be smelling like a rose if I have nothing more than a $500 repair bill.
It has gotten a little worse within 10 days weeks and she's not even a DD. BTW, under normal "babying" conditions it is fine. Being she's not a daily driver, I have time to decide but not to long because i have a roadrace event coming up in 4 weeks.
Thanks so much for your post.

John Shiels has this problem earlier this year. If I remember correctly, and from his pics, the bushings had disintegrated. Don't remember if he
replaced only the driveshaft, or the whole T-tube assembly too.
So this is not an isolated incident.

You can also purchase the torque tube guts, shaft, bushings and bearings, as an assembly from GM. I believe it cost about $600. It is not necesary to replace the whole tube. Call me if you need part numbers 908-317-4496. Good luck with your car.

I have a good realtionship with my dealership but I am still a little cynical because letting them know you are happy with them is also letting them know that you have dropped your guard. Sorry for the OT Rant

Is that the same thing?
If you do have to drive the car, like down the block to the grocery store or on the way to the dealeshjip to fix it, baby the hell out of it.
Mine is not a Daily Driver so I have time to think about this. Thats the luxury of having another car. It gives you the time you need to step back and think without makig impulsive desparate decisions. And that will save you $$ and minimize the chances of being taken. I've had several instances when I have told dealerships, "Let me think about it" and to later discover a better solution.

If it were my car, I'd do all of the labor myself, so I'd only be in it for 400.00 dollars or so. But if you can't (or choose not to) do the repair yourself, I suppose you are at the mercy of whomever swings the wrenches.

One thing I have learned - the majority of dealerships are opportunists. They are experts when it comes to Omission and people like myself generally are forced to accept whatver they say, especially when they have your car in pieces. You cant say "Put it back together and I'll try someone else."

Well, the consensus is that the clacking noise is due to the bushings
starting to come apart.
Other possibility is that a bolt or 2 may be loose, making contact, which might be the best case scenario although that may be unlikely.
And I guess ther could always be something else wrong but in gathering information and opinions from a few of you guys, it sounds like the bushings.
So I ordered the upgraded aluminum bushings from Ecklers today. I now need to work on getting the TQ Tube taken apart by someone who I can rely on and not rape me and sell me something I dont need, like a brand new tube (of course If I truly need it then so be it) once they have it apart. I'm definitely at the mercy of someone here butif I can come out of this with a $800-$900 bill I'll take it!
I'll let you guy know what happens. Thanks for all your input.
