hub overhaul question
hi folks,
Last night I took apart/repacked my front hub, first time after a few years of riding. It all went smoothly, a little too smoothly maybe. My book (Zinn art of mtn bike maint) made it sound like the final adjustment would be a tedious process. I put everything back together again, and it sounded, well, like it sounded before. I tweaked it a couple times, no change that I could notice. Put it back on my bike each time, the wheel spun fine. Rode it to work this morning, no problems. The only difference I could notice is that the front brakes squeal like never before.
So the question: how do you tell when the final adjustment is right? The book really wasn't clear, except when it sounds/spins right.
Thanks a bunch

It's a subjective/feel thing. If you can feel any indexing at all as it spins it is too tight.
Ideally you want a minute amount of play after your final adjustment to compensate for the preloading exerted by the frame or fork on the hub when mounted in the bike.

I'm a newbie at bicycle maintenance. What is "indexing" as used in your sentence?

Kirk, practice does help. I'm sure you'll get it.
Indexing is where it feels like there are little detents as it spins-this is probably a lousy analogy, but picture the way a socket wrench feels as you turn it. It's kind of like that but much less pronounced.
