I was investigating a squealing rear brake at the weekend - the brake seems fine but there's lateral play in the wheel which is causing the brake to drag.
The axel appears solidly held by the QR but there's quite a lot of movement between the hub and axel. Not enough for the wheel to foul on the chainstays, but still an alarming amount of movement.
I've never dismantled a hub, so:
- what's the likely problem? Is there something which could just need tightening up, or am I more likely looking at replacement of the loose hub bearings. Or could the whole axel be worn?
- how straightforward is it to replace the bearings? Looks easy enough on Youtube, but in reality....?
