There has been this knocking noise coming from my left rear side/tire. I don’t remember exactly when it started but I can say it has to be about 3-4 months already. It started out as small noise but has gotten bigger over time. However, when I brake the noise stops. I don’t really know what to do. I would at least like to go in to a shop having somewhat of a knowledge regarding my issue. Thank you in advance.

That may well be a loose hub bearing, especially as you say the noise disappears on braking.

Take this in to be seen to ASAP as in the worst case you could loose the wheel...

  • Yup. Has happened to me once. Missing lug nuts, actually, Ultimately found it was a missing lug nut (from a previous repair shop - which I make sure avoid - a national muffler chain). Very risky and I was lucky indeed . In hindsight it was embarassing.

There are a number of possible reasons for the noise, from the hub/wheel bearing mentioned above, to simple loose lug nuts.
