3 point started making mild squealing sound

[DHJR43]

Good Morning Gentlemen,
First I would like to thank everyone for sharing your wealth of knowledge
and experiences. My question is my 09 kubota L2800 has started to pick up a slight squeal when i pick up my 3 pt grader. Other than the sound it picks fine. Probably does it approximately every other time but not consistently. Sounds almost like fluid traveling thru a
valve or something. All fluids and filters were changed 60 hours ago. It's not a loud squeal but might be getting a little worse.
Tractor has 160 hours on it and is still under warranty so gonna take to the
dealer but still curious if anyone has any ideas on anything to check.
THANKS FOR EVERYONE'S INPUT
Don

Does it sound like a relief valve going off. If you raise the 3pt lever up to max, do you hear anything?

You might install a 3000 hyd gage in the hyd system and monitor the pressure when using the valves.

I APPOLIGIZE FOR THAT LATE REPLY J J ! I was out of town for the weekend
and wasnt able to try the gauge on the hydraulic pressure. I will try that and thank you very much for your advice. Oh and as luck would have it my warranty
ran out in july !

THANKS
DON
