Cat 315 CL pump noise/vibration

2005 Cat 315CL with 9000 hrs. Last fall this noise started. Would only do it when using multiple functions at once, like digging, or extending out to dump. Its a grinding/vibrating type of noise coming from the pump side of the machine. Well, i discovered I had metal in the system, so off to a Cat dealer it went. They put a new pump on. I've just got back to digging with the machine after the long winter up here, and wouldn't you know, that noise is still there at times. I just did an oil...
