Gear/Transfer Box Problem

Ive got a problem with the drive on a 1985 ex military 110.

Taking it out at the weekend a friend knocked the diff selector with his jacket. Trying to get it back in to drive, I could get the high/low/diff lock etc to engage but when I select a gear and lift the clutch I get a horible gratting.

Ive checked the linkage on the diff selector and they look fine and I can get all the ratios etc but I cant get into gear.

Im trying to decide it its a gear boix or transfer box problem. Any suggestions?

hi/lo lever linkage probably needs adjusting or slack removing it can be ajusted at lever end by moving it around on the splines or by nuts at rear end

There did seem to be a fair bit of slack in the linkage, but as Ive never worked on it befor eId not considered that. I will have another look tonight and see what if anythng I can do.
