Hi! I just went through the same thing the other day, an unexpected noise coming from the rear of my bike, however. Nothing when i wasn't on the bike and minimal sound when i moved my weight forward. I snapped the axle. This can cause your wheel to lose alignment under load and rub your brakes or fork. Inspect your fork and brake for any strange deposits on one side or the other. Rubber dust buildup would be an indicator that you're rubbing the tire against something, which means loss of alignment.

I rode my bike for a good 20 miles before discovering my axle break. It didn't seem bad at first, but by the time i got home i was worried and annoyed. Catching this now could save you quite a bit of damage to repair later.

You can check for this by removing your front wheel, removing the QR skewer and any bolts or washers threaded on your front wheel axle then attempting to twist the axle. If one end turns and the other doesn't, you have a broken axle. You may not even need to do that if it is broken, as the axle will probably turn while you're removing the bolts.

Initially i was distracted from the hub/axle/freewheel by the squealing noise coming from my tire rubbing my chainstays and brakes. Sometimes the noises are just symptoms of the actual problem.
