light popping/clicking in rear hub after cleaning

...and it's driving me nuts. As the title says, it's a light clicking random like popcorn kind of sound. It doesn't happen the same point of each wheel revolution for instance. Might I have to relube something that may have gotten wet during cleaning?

Someone help me, I need a quiet bike!

After looking further I've also discovered that it doesn' t make the sound when I tilt the wheel on it's side, only when rotating upright, it's a very delictate kind of click.

I have something similar at the moment, which I was just going to search. In my case, I think it's a loose lockring on the cogset... is it only in one gear or across all?

You might have fushed a piece of sand or grit into one of the rear bearing races. That used to happen pretty regularly to me when I'd bomb my hybrid down a levee-top dirt road got get to work & back. Bike would end up caked in trail grime, but worked just fine... Until I'd wash it.

Only way to tell is to repack the rear hub. It isn't difficult, just potentially messy. Keep a big magnet nearby to catch and hold the bearings, wipe 'em off, wipe off the cones & races, and apply some big dollops of grease.

Only part you'll end up doing several times is adjust ing the bearings so they're not wobbly, but aren't grindy-tight.

Once you quell the noise, apply some Vaseline to the area around the lock nuts to keep out future sand particles.

If you have cup & cone hubs, make sure you adjust the bearings slightly loose. You'll be able to feel wobble in the axle by hand. And with the wheel installed and QR barely tight enough to hold the wheel on, you'll feel some wobble when pushing the rim sideways between the pads (2-3mm). But, when you tighten the QR fully, it'll compress the axle enough to remove all play.

Cartridge-bearing hubs should be adjusted for no play since there's no lateral loads on the bearing from the axle or end-cups. But some poor designs actually load the bearings sideways.
