Mk3 1.8 ticking when moving ??

A&Q about 350Z
Q:

Clutch in/out makes no difference, i jacked it up today and looked for play in the CV joints, they seemed (on rough inspection) OK but when i turned the wheels there was a light knocking from inside the gearbox. Any ideas? Terminal? cars done 250K BTW.
TIA Mark
EDIT: Acceleration/decelertion makes no difference.
A:

does it in neutral too, any ideas?
A:

Thrust bearing at a guess.
