Diesel rattle below the transfer case lever at 1800ish rpm

[Murray]

has anyone solved the odd rattle coming from below the transfer case lever adjustment knob. It's not the linkage to the cable and the collar still has the split pin. Any accelerations at low speed around 1800rpm seem to cause this rattle/buzz. Dealer has tried a few things. I have requested access to the technical documents to see the schematics! Bottle of red to anyone that can solve it !

Have you had hands on the transfer cable linkages to check their locknuts are tight and that the lever balljoints are still good and tight? Access via the transmission tunnel side panel and down from the top by removing the gaiter surround and pulling the gaiter up. Also worth checking the lever housing securing bolts are tight too.
