Ouch, Mick!
Odd thing is, I too have heard an occassional clunk--
in the area of the undercarriage behind passenger seat.
But other than that, seems to be running fine.
I had new CV joints, rotors, ball joints, etc before leaving
for Mexico last December.

Yesterday, I heard a soft clunk just after disengaging the
clutch out of first, then again, out of second gear.
I wondered if it was just stuff under the jump seat shifting.
No trouble shifting, tho reverse has always seemed stiff.

I am *concerned.
Anyone have a clue as to what these "clunks" signify?
