07 vibe radiator fan noise

[oldsman350]

Guys i noticed a noise from the fan on the the radiator. The motor is still working but it makes a knocking noise. I checked the fan blade and it seems very loose and this is the probable cause of the noise. Is there a nut or something that could have loosened on the motor to cause the fan to come loose. I've already priced a motor and they are around $100 from O'reilys. Can anyone provide any pics of the front of the fan where it attaches to the motor.

try this. I have the same issue and have been looking at a new assay. or an aftermarket retrofit. Not sure what is the best choice. I will be pulling the shroud this week to see if I can tighten the nut.
