Freehub has started slipping, what can I do?

Check the freehub for wear to see if it needs replacing or just cleaning and relubing. To do this, firmly grab the splined body and give it a wiggle. If it moves more than a couple of millimetres side to side, replace it. Otherwise, a good clean and oil will do fine.

Can a freehub come loose?

If the freehub has come loose for whatever reason and the bike has run any distance with the bolt loose then the hub interface could be damaged.

Freehub vs freewheel

Freewheels predate freehubs. They’re still found on older bikes and the majority of modern single-speed bikes. They’ve been superseded by the freehub on multi-speed bikes though, as it’s lighter and more compact, so it can handle smaller sprockets and wider gear ranges.

Why does my rear cassette slip?

Why do freewheels click?

When the freehub body is driven in the opposite direction, the pawls can’t engage with the teeth of the drive ring, so it is able to spin freely. The pawls click up and down over the teeth, which is what produces the buzz of the freehub.
