There is, but the snap rings just hold the spider on the shaft and the rollers on the spider. It should just slide back into the tripod. There is nothing actually holding it in there except for the boot clamp, and then of course when in the vehicle it can't pull out because the shaft is attached to the hub.
Needs to have sufficient grease but don't overfill it. It needs to be able to move in and out with suspension motion.
Then just use the 4" hose clamp to clamp the boot back in place.
It'll continue to pull back out if you don't have the axle nut removed and the splined shaft loose from the hub (at least moving freely). Otherwise the spindle swinging outward while the upper ball joint is disconnected pulls the shaft apart.
