Clunking from rear of midget

[Mark Jermy <mj2@ukc.ac.uk>]

Could this be a propshaft CV joint?. If it always happens going from reverse
to forward, it could be that the CV is worn and has some backlash, taken
up when direction is changed. It could also be axle CV joints, I don't know
if the Midget has these. Or, possibly diff, I don't know much about diffs.

Just my 2p worth,
Mark.
