How do I know if my bike headset is broken?
Diagnosing a loose headset
To be sure, raise the front wheel off the ground about 4 inches/10 cm and drop it and see if that re-creates the clunk or rattle. Another test is to hold on the front brake and rock the bike forward and back to see if you can get the front end to knock or clunk.
How do I know if my headset is worn?

How do I test my mountain bike headset?
To do this, place one hand over where your fork crown and lower headset cup meet and use your other hand to hold your front brake on. Now gently rock the bike front to back. If your headset is loose you’ll feel a knocking through the hand that you’re holding over the lower headset cup.
How long should headset bearings last?

When should I replace my headset?
If your headphones sound okay at low levels but get increasingly worse as you turn them up, replace them. This is mostly an in-ear headphone issue. If your headphones keep falling out of your ears, then it really doesn’t matter how great they sound. You’ll only get to enjoy them if they stay in.
Do you grease headset cups?

How do you test headset bearings?
Diagnosis. If you can’t get the fork turning smoothly without the headset rocking or rattling, check the bearings. To do this, pull the fork out of the bike and pop the bearings from their cups. Roll them between your fingers – they should feel buttery smooth; if not, it’s time to replace them.
How tight should headset cap be?
When tightening the headset top cap it MUST push down on the stem, or the spacer above it, and not the fork column itself (the top cap pushes down on the headset which tightens it up). Do up the headset top cap until it is just tight — at this point you should be unable to turn your stem spacers. Do not overtighten it.
How do bike headsets work?

Are all bike headsets the same size?
Threaded headset sizes are designated by the outer diameter of the steering column. This can seem confusing, because the head cups do not measure the named standard. The threaded standards are 1 inch, 1-1/8 inch, and 1-1/4 inch headsets. The various standards are generally not interchangeable.
