Dump Truck Bed drops

Dump truck bed lowers too fast slamming onto frame. It’s a single cylinder lift with fluid in cylinder itself no tank. If any load is in the bed you can not lower at all it will almost free fall . I have to dump all material at once

what model do you have / the year
2004 international 4300
If you raise the bed and release the control, does it stay up or start to sag ?
If it sags, it is a leaking packing
If it stays but you can't control the descent it is a bad spool valve.
