Tech Need help - something's broken...

Apr 22, 2014
Noticed quite loud clanking soudn delivering soft pushes into frame (CrMo bike), coming from the front wheel. As faster I go, as louder are sounds. The wheel itself rotates with an irregular noise which is coming from the front hub.
The wheel (A-Class) is almost new - did not run even 500 kms.
I've never had any hub problems before and have zero experience with them. What are the preferred actions with such symptoms?
Thank you.
