Hello,
I finally upgraded to the 13/14 CF driveshaft with Tob's adapter. So I take the car for a drive and I hear a strange humming sound coming from the rear end. It only came on at higher RPMs and load didn't seem to effect the noise. I took the car back and lifted it up, I checked the pinion angle and adjusted it so that it is 2 degrees off the trans angel, I checked all the bolts and rotated the driveshaft, nothing looks, sounds or feels wrong. I took the car out again and its still there.
Since I got the driveshaft used from a member here I'm thinking I was sold a bad DS and the CV joint is the culprit, I'm really hoping it isn't that but if it is, how long would a bad CV joint survive? Any other ideas? Could it be just a side effect of a 1 piece driveshaft?
EDIT: For those who did the upgrade, was there an increase in NVH? Can you describe it.
