The Snap-In Thrust Bearings are easy to "snap in".
One key is that there is a small diameter retainer ring on one end and a larger diameter ring on the other. We want to insert the small diameter.
You'll quickly get the feel for how to get them inserted. Push on the left side of the bearing so that it's all the way in. Work your way around the bearing counter clockwise pushing the bearing towards the center and down into the hole. They install very quickly once you get the hang of it.
They should all be inserted the same direction so that the hinge pin is inserted from the end with the larger diameter retainer rings. I choose to orient the larger diameter so the hinge pin would be inserted from the tip of the stab.
