whining noise from new driveshaft
 

Hey guys I just installed a new 1 piece aluminum driveshaft cause my old OEM 2 piece broke. But now witht the new aluminum ` piece shaft i get thise whining noise thats driving me crazy.
I can hear it from inside the car and ppl outside can hear it while im driving by.
need help fast!
possible defective part?

Is it any beefier than the OEM? Perhaps it's rubbing on something underneath while the car's off the jacks. If you check that double check the installation. I imagine it's fairly straight forward but you never know, right?

I did double check to see if its rubbing anything
make sure it wasnt tocuhing the exhaust heat shield
and im sure it was installed correctly
theres only one way to fit the driveshaft
and its about the same size if not slightly smaller
its the z1 1 piece driveshaft
