Transfer 'clunk' ?

[KERRSURF]

Hello troops, I replaced a knackered hardy spicer joint on the rear prop, it was making orrible noises ( must remember to grease em in future!). Job was fairly easy and the noise dissapeared but I have a new noise.
I have manual hubs fitted and without engaging them ie: not locked for 4wd, when I press the 4wd selector button on the shifter I get a regular clunk from transmission.
The front prop is well greased (now) and turns freely by hand when 4wd is disengaged and no squeaky or grinding noises and I can't detect any free play in the joints.
could I have a transfer or gearbox issue?
The clunk is gone as soon as I turn off 4wd with the switch.

I was offroading a while back and I got the clicking thumping broken CV joint noise and I replaced this but not used 4wd since so I dont know if the noise was there a while back.

Any help is of course greatly appreciated. cheers Alan.

I think I might need a font diff first richard, if my fears are realised.
I'm gonna get it on the axle stands this week and run it without rear prop to see if it is in fact the front diff making the clunk.

I'll be in touch for spares if I need them.
