Factory Aluminum Driveshaft?

[JoeliusZ28]

So I have two aluminum driveshafts, one of which I just bought in an effort to try to fix a driveline vibration. Both individuals I bought these driveshafts from claim they are factory driveshafts (and I believe them).

Question is, whats the difference? Were there two part numbers GM used? Does one of these not look factory? There isnt any particular reason i want to know, just curious.

Believe they are both correct . A4 damper, m6 no damper

I have the bigger looking one on my car now, pulled it from my neighbors 1999 Camaro SS A4.

Believe they are both correct . A4 damper, m6 no damper

Whats the technical reason behind that? Is there any reason not to interchange the two?

Mine is the same as the bigger/cleaner one.

I have removed two aluminum driveshafts from M6 cars and they both had the dampner.


Do they both have a three rivers sticker on them?

I have two aluminum driveshaft at the shop and they both have the dampner. They also have the plastic U-joint piece that you have to melt to remove the U-joint.

Thanks Fred, always going the extra mile

I will check this the next time I am at the garage.

interesting, i need to replace my driveshaft. looks like it was spun up and dropped on a drive shaft loop. engraved all the way around. rather strange.

Maybe smaller one is from v6 and larger v8.

[JoeliusZ28]

Nah ive owned V6s, they didnt come with aluminum driveshafts not even the Y87 performance cars.

I think Larry is closest to the answer. It looks like the smaller one is the earlier 3rd gen / 1LE drive shaft and from the sounds of it is actually the stronger of the two. Hmm.

I wonder if i can remove the damper by the yoke?

[MunsterZ28]

correct me if i am wrong, but the v6 cars came with a 2 piece drive shaft correct?

[1BADAIR]

i dont think the dampner will be a bad thing,

[JoeliusZ28]

its additional rotating mass is it not?
