To my mind a high shrieking means a problem with gears.So a service woud be best.

When you say that you oiled the bearings, are you referring to the motor bearings? If not, put oil on them. All you need is a very tiny drop.

Or wrapped around an axle or drive shaft? Hi shriek usually means binding?
Can you remove gear cover? Check each axle to make sure it’s not cracked?
