Hi and thank you for your question.

If the noise came from the lower left, that is drive shaft area. The clutch is on the right side and typically does not make a noise, clunk or otherwise, when it fails and is slipping. I suspect you have either broken a drive shaft or stripped the splines in it. Sounds like you are going to have to pull the rear wheel then take the swing arm off to inspect where the drive shaft engages the transmission output.

That is a link to a parts diagram of the drive shaft assembly. Typically when they break they will break the threads off just above the splines. They can strip the splines on either the front or back end of the shaft, where they engage the U joint (tranny side or drive shaft side) at the front or the coupler at the differential.
