Freewheeling in both directions

Was accelerating from a stop when I heard a snapping sound from my old cheapo freewheel, and felt all the resistance suddenly go off the pedals, like what happens if your chain falls off the sprockets. But the chain is still engaged.

The freewheel is now spinning freely in both directions and makes the clicky, ratcheting sound when the pedals are turned both forwards and backwards. Pedaling forward doesn't turn the wheel anymore.

Is there any chance of a flush-and-oil process reviving the freewheel? I had thought that was called for when the pawls were stuck in the up position... but if the pawls were stuck up, wouldn't the freewheel be silent when spinning forward or backwards? I guess I don't understand how the freewheel is able to make clicking noises in both directions.

It's broken. You heard it break. Get a new one, they're cheap.

You can try flushing it with oil but I expect it's truly broken and the only "fix" is replacement. As noted, they are too cheap to spend much time and effort on.

No sense doing all the work in an attempt to revive this freewheel. You heard it break and are seeing the results. Time to replace your freewheel.

You stated the freewheel is a cheapo freewheel in your very first sentence so get another cheapo freewheel and be done with.

All the responses are appreciated.

I was wrong about the noise - after getting broken, the freewheel wasn't making a true clicky ratchet in both directions, more of a dull whirring. For fun, I gave it a bath in odorless mineral spirits, and it spins cleanly both ways now with a dull, metallic scraping sound.

So I guess it really is a case of something truly breaking (either pawls or springs or whatever), and not just a case of the insides getting gummed up. I guess that shouldn't really have been a surprising conclusion, given the sudden nature of the failure and the fact that I had just flushed and re-oiled it just months ago, after the winter. I just like to be able to visualize how things work (or don't).

I'll get a replacement soon and keep the freewheel to disassemble as a rainy day project, just for a learning experience. I was planning on replacing the freewheel eventually anyway, cuz it and the chain were getting up there in mileage, so it's not much of a loss. Plus, now I get to practice installing new stuff.

Thanks again.

Probably need a new chain, too. Old chain with new freewheel can result in chain slipping.
