Hi. I have a LG refrigerator model 349R. It is in very good condition, the only problem is the condenser fan motor that gets noisy some time. I remove the part and spinned the axis. I heared some squeaking so the problem is the motor. I opened it and here are the pictures. Is there an alternative to replacing the entire motor :
1. Can the ball bearing be removed and replaced?
2. Is there a way to grease it (although I believe those bearing are not meant to be greased)
3. What is the purpose of the hole on the side. I found some sort of gum in it.
Thx for your help
