Unhook the supply hose this will break the vacuum. The only Toyotas without a seal on the rod are the reach and order pickers. All others have seals on the rods. If the rod is hanging up in the same spot then you have a dent in the tub. It will need to be replaced. If you have a little more time and sometimes it will cost less, but only if you have a very talented hyd shop who can make you a new tub. Keep in mind is going to need to be a metric size. The newer Toyota's starting with the 7 series has a valve built in the bottom of the rod. This valve moves oil from the top of the piston to the bottom as the rod moves up to provide a cushion while staging. As the rod seal goes bad this valve has a tendency to stick and cause a hyd lock and cause the mast to miss-stage.
There is a snap ring that holds it in place. once you remove the ring. With the snap ring plier's pull the valve out and with some brake clean, clean the valve ***'y and with a round punch push down on the poppit is not stuck. The Toyota seal kit will come with tool to get the piston rod seal past the threads.
