Good job Randy on putting together this kit. To elaborate on your emergency kit:
1. Assuming that the small screwdriver is used for removing the cap off the wheel hub, make sure it's a slotted screwdriver.
2. If you use wire cutters to remove the cotter pins, then make sure you have two new cotter pins in the kit. Another option is to use a set of needle nose pliers to remove the old ones and then straighten them out. The new spindles come with a new design - there is no cotter pin, but a retaining washer that goes over the threaded spindle and has a tab on it that gets pressed into a slot in the new nut to lock the nut in place.
3. Make sure that you have a tool to remove the old nut and put the new one on. A pair of groove joint pliers will work, or you could carry a socket and ratchet/handle.
4. A cold chisel might be necessary if the bearing gets seized to the spindle
For those of you not inclined to make such a repair your self, I would highly recommend that you at least carry the bearing and seal kit so that a repair shop would at least have the parts.
