J.D. 3320, rear lift groans when lifted

[foodplot123]

Hey Friends, My 3320 has a lift noise that occures every time i lift it even with no implement,but loader with one, i can feel the line chatter coming from the pump behind the seat, there's plenty of fuid and have no problems lifting anything it just makes that groaning sound like air is in it ,could this be a filter problem? sounds like the pump is starving for fluid, mabe a vavle? can anyone tell me what the problem may me? thanks friends, foodplot123

There is no "pump behind the seat" on a JD 3320.

I know, my Dad's 3720 does that too. All right, 500 posts!

It's normal, mine has done it since it was new, and so have many others.

My lift is barely audible. I have the power beyond option installed which re-routes some of the lines. This may make a difference.
