118,000 miles. Supercharger sounds like the bearings are going bad on the drivenose section. No noise until it warms up. Nose feels rough when I touch it while it's idling. More so 1/2 inch from beltdrive end. Noise goes away at off idle and up. Can a person replace just the bearings? The oil looks brand new.

Thanks in advance,
Gayle

Magnusun products sells reman superchargers
Ive used other companies remans, but
they have not been the quality of the magnusun
You can purcharse just the nose assembly, but
after 60k it is recommended that you rpelace
the entire unit.

OK, you have just described the most common problem that the M90 supercharger has. Noise at idle that goes away with rpm. Chances are it is the drive coupling that connects the drive nose to the supercharger gears. The way to check is as follows. Pull the belt off the supercharger pulley. Move the pulley back and forth. If you feel a clunk with change of directions, it is the coupling. The supercharger should spin easily and smoothly, if not the nose drive bearing are going bad.
