I originally took my car into the dealership for a driveline vibration and they said it was my differential so they replaced it under warranty, but im still feeling the vibration. They swapped out driveshafts with another s2k and the vibration was still there. I feel it coming out of 2nd if im pushing the car hard its most noticable, all the way up to 80 in 5th then it smooths out. Its almost like its clicking and I also notice it more when Im cornering hard. Can somebody please tell me what this is!

 

i had the same problem.
if i took it to redline i would feel a shuddering feel from the rear end. and when i made like long right turn sweepers it would shake the whole car as well.

then later on my driver side drive shaft snapped. and my diff broke at the same time. replaced both and now it drives smooth.

it seems like you've done both already and its still doing it?!!?

 

Yeah they swapped the driveshaft just to check if the driveshaft was out of balance but the vibration was still present so they ruled out the shaft. Could it be one of the joints? Now I'm feeling my car pull to the right or left unexpectedly. Sort of like when driving on 2 differnt road surfaces. Could it be becuase my rear tires are very worn down?

 

Did the dealership check for wheel imbalance? what about the half axles? These could also be a cause of the problem.

 

sounds like a rear cv shaft not the main drive shaft have them check the rear cv joints/shafts.
