Still has to bolt on to the dampeners on each end???

Yes, but I've had it off several times trying to figure out the issue. There's nothing wrong with the bolts. I may put the stock driveshaft in and see if I still have issues. I'll have to get some new bolts since I didn't keep mine. Plus, if that's the problem, I'll have to get another driveshaft and swap again. I just want it fixed. I'm tired of messing with it.

More than likely the Driveshaft itself is not at fault. Something is not lining up in your car like it should.

Sounds like something is flexing.


Check the Diff bushings and the transmission mount and motor mounts.

Also check the cradle bushings.


If the fuel tank has ever been removed it may not be seated all the way. Same with the heat shield.

Good Luck!

Well if you took the drive shaft out yourself then you would know.

Hell, other than checking of the mounts and bushings I haven't got a clue.

Before I replaced my drive shaft when the hanger bearing came unpressed I had a similar deal. Only on acceleration would it shake. Replaced the stock shaft (with another stock shaft) and all was good.

BUT, I had a noise AND it was a two piece shaft. Obviously yours isn't doing that with no bearing in the middle.

The fuel tank has been out, but the issue was there before I took it out. I put solid mounts in the cradle when the fuel tank was out. Motor mounts, trans mount, and differential bushings appear to be fine. The problem started after the LS Fest where I autocrossed and took two runs down the drag strip. The driveshaft wasn't assembled properly and when I put some power to it, it crushed some of the aluminum in the driveshaft. I sent the driveshaft back, they rebuilt it and I received the same one back.

put stock driveshaft back on and then try it !

Did you ever get the issue fixed? I'm getting a heat shield rattle and can't seem to figure out where its hitting.

If you have the stock mufflers it could be that. Sounds like what you'd expect from a heat shield rattle. I had it bad when I had the stock cans on.

These things are so hard to find sometimes.

Yes, the driveshaft was not assembled properly from DSS.

Well thatnks for the update doo doo head. :laugh:

That's awesome. Glad to hear it's all good.

I'd like a better DS. I couldn't believe how thin these things are when I replaced my broken one for another stocker.

My bad. Been dealing with other issues.

Holy crap. What kind of power did THAT? :confused0068:

625 at the wheels and some wheel hop. DSS said that driveshaft had a defective weld. It was 2 days old.

I had the same issue with my driveshaft hitting the heat shield. We have to bend the shield up so it would stop hitting. I also have a lot of vibration abouve 90mph, rotated the DS a couple time and it temporarily fixes the vibration but it doesn't go away completely.
