Noisy freezer evaporator fan motor

Removed the shelves from the freezer and the brackets holding it along with the covers for the light and plate for the ice maker (we don't have one). Pulled the ground wire from the tab off the port for the ice maker. Removed back plate exposing the fan motor and then the 4 hex screws holding on part #23 of the diagram which the fan motor is mounted to. Flipped it over, unscrewed the 2 hex screws from the fan motor mounting and removed it. Removed and replaced 3 wire connectors on new fan motor. Installed new fan motor and new grommets but used the old screws because the provided screws were larger. Pushed the new fan on to the motor shaft. Reassembled. Half hour most.
