I know I've done this -- let me see if I can recall the procedure. I need
to replace three more sometime soon (they're contagious -- once you get
one on a wheel they start to multiply). I didn't completely remove the
tire and tube, although if you're doing several it might be more
convenient. I have chrome wires so new paint wasn't an issue.
1. remove wheel from vehicle
2. deflate tire completely
3. use spoke wrench (and penetrating solvent, usually) to loosen nipple
4. sometime around this step the broken tip should be encouraged to fall
out through the center hub, if it hasn't already
5. remove long end of broken spoke from nipple (taking care to observe
exact position relative to neighbor spokes). If you're planning on
keeping the nipple, don't let it fall inside the rim.
6. if you need to replace the nipple, break tire bead loose from rim on
one side and squish it down to expose inside of rim. Pull away protective
rubber band (if present) that covers spoke ends and nipples. If rubber
band not present, consider acquiring one.
6. feed new spoke through hub, threading it through neighbor spokes, and
try to start it on nipple
7. tighten nipple with spoke wrench, but not all the way tight. Tap
several other spokes (of same length) with loosely held spoke wrench and
listen to the tone. Memorize that note, and tighten new spoke to match
(higher note is too tight; lower note is too slack). Recheck adjoining
spoke tones and opposite spoke tone to make sure you haven't altered them.
8. if you installed new nipple, make sure rubber band is replaced,
covering new spoke end. Inflate tire carefully, making sure inner tube is
not pinched or twisted, and that tire bead seats in rim. Recheck spoke
9. (optional handy hint) Clean all grease from inside hub. Use clear
silicone sealer to cover spoke heads. This will keep hot grease from
flowing out along spokes, thereby attracting dirt. Let dry. Re-grease hub
10. replace wheel on vehicle
Hope this helps.
