Narrative:

Coming in; I noticed a noise in back of the plane. We both reported it to captain upon landing. Upon re-boarding flight; the #1 flight attendant allowed the flight to board the aircraft without the #2 on board. During boarding; the mechanic asked to speak to me and the #2 flight attendant. We both went up to cockpit to talk to them. We both expressed the plane was broken; loud noise in back. They said they didn't find anything. So on taxiing and takeoff; #2 flight attendant and I were on the phone to captain letting him know. When we heard the noise about 1 hour out; the captain called and said we had a hydraulic pump out and the other leaking; but we would make it to ZZZ. I was not comfortable with that. Then the captain called and said 'maintenance said to land in ZZZ1.' thank god.
