Sometimes my blower motor for the HVAC makes a rubbing sound when I make a sharp right turn. Any ideas why?

Please add the model and year for you car when asking for help...

If a motor bearing is failing/failed, then the centrifigual force of a turn will shift the weight of the motor shaft, causing the noise. In some blowers, braking will result in the same sound due to the deceleration forces.

I took the blower out 6 month ago and put a drop of oil on both sides of the motor so the bearings should not be dry?

the blower motors are made pretty bad.. i have gone through 3 blower in the 16v in a few yrs that dont like taking corners the bushiing wear out fast , yours is toast it needs replacing , i dont think anyone sells just the bushing either good luck
