It has been a week since I changed the motor oil and filter, drained transmission, removed hydraulic filter and cleaned and replaced it,filled trans with new fluid, changed fuel filter. I asked if there was a way to purge the air from the system and told to move the 3 pt up and down to remove any air in system. I tilled about a1/3 acre with no problem. Yesterday will till a small spot in garden the 3 pt started squealing when beening raised. What could be the cause of this? Speedy2

The squeal is probably the overpressure bypass.
It can squeal when the 3-point is raised too high. Adjust the feedback rod so it pushes and resists your attempt to lift the last few inches.
Or if you hear the overpressure bypass squeal before the implement is lifted very far, then possibly the implement is too heavy, or the shutoff valve under the seat is near closed.
I doubt this is a trapped-air issue.
