need a recall number i was just wondering what the number for the technical service bulliten for the drive shaft on our cars where they replace it with an aluminum one from the ls1 cars . i remember reading somewhere there was one, but i can't find the number for it. also i already went to the dealership and asked them about it, but they couldn't find it on their database. now they did say that if i found a number for it, they would do it for me.

OK.... Bare with me here not sure whats corerct so Il post all I have.
Was told this is the number,
#67-41-01
published march 14, 1996
--- Then theres this post that shows a bulletin number.
Q: What is that vibration I feel around 1800-2000 RPM?
A: This problem is an unbalanced driveshaft. Most people with the problem feel it at its worst between speeds of 90 and 120 MPH. Others claim they can also feel it by slowly bringing the RPMs up to the 1800-2000 range with the car in park or neutral. But that isn't necessarily the same problem. Some even start to feel it as low as 60 MPH. It usually starts with a mild resonating vibration you can feel through the gas pedal. Then in at 80 - 90 MPH, the vibration intensified and feels as though it's coming from the center of the car.
It seems cars are coming off the assembly line with the unbalanced drive shafts. A Technical Service Bulletin (#674101) addresses this calling for replacing the stock driveshaft with a 3rd generation all-aluminum driveshaft (part #10085375) which came with the 1LE equipped cars. Although there have also been instances prior to the TSB where it was replaced with the standard 3rd gen steel driveshaft (part #26004464). Either seems to work just fine (although the aluminum one is lighter in weight). Make sure you let your dealer know what the TSB number is as it will be fixed under warranty.

If you want to read info on this, people were discussing this topic in a thread I started about somghing irrelevant, read pages 4 and 5.

Here's the actual bulletin.
Document ID# 225209
--------------------------------------------------------------------------------
VIBRATION AT HIGHWAY SPEED #67-41-01 - (Mar 14, 1996)
SUBJECT: VIBRATION AT HIGHWAY SPEED (REPLACE PROPELLER SHAFT)
MODELS: 1993-96 CHEVROLET CAMARO 1993-96 PONTIAC FIREBIRD WITH 5.7L V8 ENGINE (VIN P - RPO LT1)
CONDITION:
SOME OWNERS MAY EXPERIENCE A VEHICLE VIBRATION AT HIGHWAY SPEEDS. WHEN MEASURED AT THE DRIVER'S SEAT TRACK, THIS VIBRATION WILL BE A 1ST ORDER DRIVELINE FREQUENCY. THE SAME VIBRATION CAN BE CONFIRMED AT THE AXLE PINION NOSE AND AT THE REAR EXTENSION HOUSING OF THE TRANSMISSION.
IMPORTANT: WHEN MEASURING VIBRATION FREQUENCY ON A HOIST, THE REAR OF THE VEHICLE MUST BE SUPPORTED BY THE AXLE TUBES IN ORDER TO MAINTAIN THE PROPER VEHICLE TRIM HEIGHT. THIS WILL PREVENT VIBRATION DUE TO EXCESSIVE DRIVELINE ANGLE. ALSO, ANY VIBRATION DUE TO EXCESSIVE DRIVELINE ANGLE WILL APPEAR AS 2ND ORDER DRIVELINE FREQUENCY VIBRATION.
CAUSE:
FIRST ORDER DRIVELINE VIBRATION MAY BE CAUSED BY BEAMING BETWEEN THE ENGINE AND TRANSMISSION.
CORRECTION:
A PREVIOUSLY RELEASED PROPELLER SHAFT IS AVAILABLE TO ADDRESS THE HIGHWAY SPEED VIBRATION CONDITION. THIS REDUCED MASS PROPELLER SHAFT IS CONSTRUCTED OF ALUMINUM LESS A PINION DAMPER.
VERIFY CONDITION PER ABOVE NOTE THAT THE VIBRATION IS 1ST ORDER DRIVELINE DISTURBANCE; PREFERABLY USING AN ELECTRONIC VIBRATION ANALYZER (EVA).
OTHER CONDITIONS SUCH AS EXCESSIVE DRIVELINE ANGLE DIFFERENCE MAY PRODUCE 2ND ORDER DRIVELINE VIBRATION CONCERNS. THE PROPER PROCEDURES TO MEASURE AND CORRECT FOR EXCESSIVE DRIVELINE ANGLE CONDITION ARE NOT SHOWN IN THE CURRENT SERVICE MANUAL. CONSULT A 1992 SERVICE MANUAL FOR THE PROPER PROCEDURE. THE FRONT AND REAR PROPELLER SHAFT ANGLE MUST BE LESS THAN ONE DEGREE OF EACH OTHER.
IMPORTANT: DUE TO THE REMOVED DAMPER, THE ALTERNATE PROPELLER SHAFT MAY UNMASK EXISTING REAR AXLE NOISE. A LIGHTER PROPELLER SHAFT WILL REDUCE VIBRATION BUT WILL POSSIBLY UNMASK AXLE NOISE, WHILE A HEAVIER PROPELLER SHAFT WILL MASK AXLE NOISE BUT MAY CAUSE VIBRATION. THIS INHERENT CONDITION IS ALWAYS THE TRADEOFF. IT IS SUGGESTED THAT THE VEHICLE BE TEST DRIVEN TO EVALUATE AXLE NOISE BEFORE AND AFTER PARTS ARE INSTALLED.
INSTALL ALTERNATE PROPELLER SHAFT, PART NUMBER 10085375.

I had mine repaired under Warranty in 1998. The problem seemed MUCH more apparent after a trip or to past the peg that stopped the speedo from advancing 
It took a few visits but they did replace it under warranty.
The true problem seems to be spinning the driveling faster then it is capable of handeling with out warping I am sure 14Psi of boost did not help it out much

i bet it didn't. do you think if i tell them that when i race, at the end of the track i got a really bad vibration. and each time it gets worse, and it happens at the most dangerous part of the track, they would have to replace it.

Yes, the car would have to be under factory warranty or extended (gmpp). Like the bulletin says, bulletins are to inform technicians of possible conditions on some vehicles, they are not recalls. If your car is not under warranty then you will have to pay for the driveshaft. They would only have to replace it if you were willing to pay for it. I knew a guy that got his replaced, but the car covered under gmpp. If you have gmpp, then you don't want to tell the dealership you are racing the car, unless you have a connection at the dealership, ex. you know the drivetrain tech or service adviser. I have an extra alum driveshaft I could sell you if you were local, Dallas area. I do not want to ship.
