Deere 290G boom shutter/jitter

[Md00738]

Have a 2012 - 290G w 3,500 hours on it. The boom has a shutter/jitter most noticeably when pulling the control back, does it a few times when extending out. It almost seems like the house is loose to the carrier, not a hydraulic issue of sorts, or a bushing is out. All bushings seem good shape. How do you check the house to carrier/slew tolerance? Other thoughts? At times it will jar you out of the seat before you can get it stopped from jerking. Has the 12'4" arm if that matters and a JRB quick coupler. 48 inch bucket. Sucks.

What do you mean, it stutters on boom raise and stick out or just one function

IIRC boom up is the highest pump pressure rating. Set your machine for max power and max rpm and pull the boom up against the stops. Hold it for a little bit and see if you feel vibration. If so, you may need the pumps rebuilt.
