Can my bad 02' C32 s/c pulley bearing be robbing me of power or is it just noisy??
My s/c pulley on my 02' C32 is making grinding/rattling noise and needs replacing and I am wondering if it is robbing me of power or just noisy not hurting my power??

Not an AMG :(
Bearing failure = increased frictional force.
Increased frictional force = decreased efficiency and ultimately more work required to turn the pulley.
Never mind the power loss.
Replace the bearing NOW before it seizes and causes significant damage that will cost you dearly.

Otherwise, you will be looking at a $1200 + repair.
Good luck!!
