I noticed that it was a bit tricky but also that it was the top cover that was a bit loose. So I took the bolts off (the ones behind the wheel) and they were a bit loose. Then, re-tightened them. Made a difference, at least in the local roads on which the noise showed up. Haven't heard anything since hopefully it will stay that way, cross fingers.
