KNOCKING SOUND - HELP!!!

Hey friends,

so this morning i spent 3 hours trying to troubleshoot this knocking sound coming from my front wheel.

I have narrowed it down to the wheel bearings or the wheel balance.


i will hear a constant cyclical knocking sound in neutral, in gear, when the bike is on or off. I removed the calipers from the rotors and the sound is still there.
I removed the front fender and the sound persists.

I removed the wheel and the forks and reinstalled per the instructions in the service manual.

First i did the forks and tested. The issue persists. Then i removed the wheel, the gaskets and the bearings and the middle tube thing. I put them all back in correctly and took the bike for a ride. The sound was GONE!

I went out for a ride and 10 min in, the sound came back.

Here is what I am thinking

When I originally had my wheel powder coated, i did not replace the bearings (even though the service manual says to) because the bike was under 1000 miles. I recently had my front wheel balanced and the guy stated that it didn't need weights. He just re aligned the tire dot with the stem valve.


The sound is getting progressively worse.

Do you think I should get new bearings and take the wheel back for another balance?

I am not sure if this is doing damage to the wheel, but I am not riding it until its repaired

I need all of your expertise.

please help a brother out!
