(Raymond/r35-c35tt) as for the serial number is 05953. It bounces when lifting up and down, when I let go the control handle it bounces just a little. It does have a bleeder but already did that. I noticed on other truck same model it doesn't bonce when you release the lift **** instead it stop at once. and it bounce with or without a load.

A little more information may help us give you a far better guess as to what you are asking.
model? serial? make?
when does it bounce? driving empty and not touching the controls? while lifting? when you stop lifting? loaded or unloaded? in reverse? only when changing directions?
how high does it bounce? does it have a bleeder on the lift cylinder? does it have fingertip controllers or levers and linkage to the control valve. does it have a hydraulic accumulator?
