Hi Bosswrench,

Thanks for popping in and taking a look at this thread...

I don't doubt that other cars have had success with the OEM halfshafts, even the modified cars that you mentioned.
But that doesn't change the fact that I do have a driveline vibration with my car.
There are not many parts that rotate outside of the wheels, tires, and halfshafts, so that's where my troubleshooting began.
And since the vibration was aggravated by lowering the car, I immediately faulted the halfshafts.

When I open up the throttle in any of the lower gears, the vibration is so bad that the shift lever feels like its going to shake right out of my hand!
I am absolutely not opposed to doing further, in-depth troubleshooting to figure this out.

If there is another issue (or issues), I'd love to find it.
Any ideas where to begin?
