I have a Ford 5610S. Just changed the five O-rings under the unload valve on top of the Hydraulic Lift Cover. Very easy and simple job. However, when I got things back together and tightened down, there is a squealing sound coming from the rear 3-point hydraulic when lifting. I think there is more than likely air in the system, but I have no idea where to start on bleeding the air out of that is the issue.

It did not make this squealing sound prior to replacing the O-rings under the unload valve. I tried to attach video but it won't allow me. If you want to hear it, message me your email and I'll forward it

I gave permission to a Ted Johnson. If that wasn't you, can you request permission and I can go to email and give the okay. Not sure why it is asking permission.

Is the sound coming from the unload valve?
