Check your wheel bearings

[RocketMoto]

Changing my rear tire for the first time, and checked the wheel bearings for grease. Guess what? Hardly any in them. Whenever you have a wheel off, pull the black cover and the white plastic piece out and pack them suckers! It may save you one day.

Good work. SOP for every wheel I remove prior to fitting a new tyre. Easy to have a good look at the brake pads while you are there.
