Could not find a thread about this
So here I go

When riding off road, I get a rattle from the rear end/wheel somewhere
I thought it might be the chain rattling against the swingarm, upped the chain tension to minimize this, but it's still there
Quite a harsh rattle

Could it perhaps be the bearings? - all seems fine with visual inspection
Can it be the cush rubbers?
There is a bit of play but I did the tube conversion

A bit of a guessing situation - quite irritating but more concerned it might be something that's in the process of breaking

Thanks in advance
