My most recent maintenance embarrassment is regreasing my headset (kind of still in progress). The irony is, I did this for the first time a couple years ago with no problems at all. This time, I've made every mistake you can make. Mistakes included:
- Overtightened top cap, steering way too stiff
- Under tightened top cap - front wheel shuddering when I braked
- Put the compression ring in the wrong sequence (I know, how can that happen!) - steering wobbly
- Cable housing tangled and steering constrained because I put the handlebar back in with cables not repositioned correctly
- Tightened all the screws and handlebar not aligned correctly
- I'm going out for another ride today - I really, really hope I finally got it right
