Sounds like what my WD45 did when the shoulder broke off the relief spool. Had to remove the pump and rebuild it with a new spool.

I'd check the oil level in the HYD and trans/rear end first, if you have lost hdy oil and now the trans/ rear end oil level is now over full then I'd look at the lift cyl or hose.

3 WD45's with power steering,G,D15 fork lift,D19, W-Speed Patrol, "A" Gleaner with a 330 corn head,"66" combine,roto-baler, and lots of Snap Coupler implements to make them work for their keep.

I would agree with Don. Start with the hydraulic hose that feeds the cylinder. You need to pull the rear housing off the tractor to do that.
