John Deere 770CH low serial number, oil migrating

oil is migrating from hydraulics differential, seems to be coming from differential cooling pump, brakes are holding. Any ideas?

    Pull hoses off diff lock pump and put hoses in bucket half full of oil and start. If main pump is dumping oil in diff pump bucket will fill up.
