Ford 655 awful hydraulic noise

[Dannydp]

Hey guys my first time getting to use the backhoe since I bought it and done a lot of work on it. The hydraulics in the rear or making an awful noise a little slow and jerky as if it has air. I just rebuilt the boom cylinder but all the cylinders are making that noise. I can't figure out what it is any ideas? Thanks

I can post a video if it will help.

Did you try removing and reseating the hydraulic feed line/return couplers?
