My fan bracket bearing was noisy when taking it off for a timing belt change and I attempted to disassemble it to see if I could replace just the bearings.

The fan bracket bearings are NOT replaceable!

As has been mentioned previously a lip of the bracket breaks off when pressing out the bearing and rod. When attempting to press the rod out of the bearings the assembly explodes due to the way the ball bearings on one side ride in a channel in both the rod side and outside bearing race. Luckily due to the sketchy nature of what I was attempting, I was shielded behind a makeshift blast shield when the outer race let go. The other side has needle bearings it looks like.

A new Aisin fan bracket from amazon is now on the way.
