Just adding it to the thread in case someone else ever does a search.
The rear steer tire shaft is held in by 2 saddle clamps, each with 2 bolts on either side of the tire. They are removed from below. The bolts take a 1-1/8" socket and are fine thread so it seems like it is taking forever to get the bolt removed.
The saddle block which the bolts hold in place to clamp the shaft are quite large, at roughly 2" x 2" x 5"
Once the saddle clamps are removed, you need to jack the tail of the forklift quite high to roll the tire out with the shaft in place. It is held to the tire with a screw-on spacer and a castle washer to lock it on each side, similar to a front wheel bearing on a car. Bearings on each side are standard tapered roller bearings, 13687/13621 are the numbers of the cone and cup portion respectively.
That side-hole which makes it look like the shaft slips out sideways is a ruse to send you on a wild goose-chase. The only thing it is good for is holding the steering mechanism still while you crank with the ratchet to remove the large bolts mentioned above.
