I've been trying to identify what's causing a transmission 'clunk' which started making itself felt on Friday. I had a clunk ages ago but got rid of it with new drive flanges, suspension joints and bushes last year. The propshaft joints are new-ish and there's no detectable slack on them. And now there's a new clunk. This one sounds higher pitched than the old one, like tapping a resonant piece of metal with a hammer. There's a bit of rotational slack in the drivetrain (haven't we all got this?) but it's no worse than usual.
I might have a bit more fiddle later on and see whether I can narrow it down a bit.
