Hi, I run a 1986 Ex Mod 90 which is converted to Disc 200tdi, im having problems with it recently beening sluggish and heavy- bad to drive, i noticed today that the diff lock lever was in lock- took it out and put it in normal but realised that it just moves across again without using the gate- neutral, holding it across now with a bungee strap but is the box toast? It is really stiff anyway and hard to engage reverse

theres no gat neutral for diff lock it can be moved side to side at any position of the lever, if it wont stay in place have a look at the linkage
have a look at the rev plunger its possibly siezing up can be stripped and cleaned or lubed using a vice to compress it
