Had 4x4 specialists check it out............unfortunately noise had stopped as i'd not driven it 4 a while and as stated b4 the blasted thing does'nt do it unless i drive it for a long time. He said he could'nt see any fault with the transfer box bushes/mounts at all, and perhaps i should bring it back when noise has returned (very annouying) :?
As 4a skidplate on transfer box...........can't say i saw 1 there, so i'll have 2 check that 1 out?, but as i said b4, it only does it on heavy break'n after driving it 4 a couple of day, though it does'nt sound like that type of knocking noise (if you know what i mean), it knocks in rotation, i've changed front disc's & pads so its not them!
