Just a couple of questions for clarification:

What exactly does "honing" involve? In which dimension is it honed? Does it have to be fitted and marked?

What if I can get the kingpin bottom caps loosened from the tapers? Does that mean I can do this in the car?

What are the upper pivots that I may need to replace?

I've heard a lot about watching the spring. I've removed hubs and springs frequently without a problem. I've always used a screw spring compressor. Doesn't anyone use these anymore? They compress the spring and keep it that way until you are ready to release the tension.

Thanks for your input. It's a great write up so far.
