How to lubricate a plain bearing

Question

I am trying to repair a squealing heating blower motor.
The shaft doesn't have feel-able tilt play in the bushings, so I suspect the bushing isn't yet worn out. The shaft looks scratched, but I barely feel something with a fingernail. Previous attempts at just dropping in some oil didn't last long.

Update:
I tried to soak the bearings in oil, by vacuum-sealing them. For now the squealing is gone.

If that is an oilight bush / bearing then I would soak it in oil - overnight if you can arrange it and a light oil so it goes in easily even heat it a little.

The first picture looks like a needle -rolling element - bearing , not a bushing. Can't tell from picture but if it is silver , not red or yellow ,it is a needle ( steel). If a needle has spun on the shaft ,your motor is dead. A new bearing would be relatively costly and may also spin on the shaft , depending on wear. If a plain bronze bushing ,put oil on it.
