So I thought my gearbox had blown but when I transferred to 'diff lock' car was drivable. Without 'diff lock' when lifting clutch I get a knocking/slapping noise. Please advice and please advice in a cheap fashion, rather broke. Cheers

sounds like front axle but could also be center diff ,jack a front wheel up and see where play is

So it doesn't move if it's not in diff lock, or it does move but sounds bad?

Moves fine with diff lock on. Doesn't move when not in diff lock and that is when the noise occurs.

Check front and rear props and diffs. Take rear prop off, stick in diff lock and if it drives it's the front diff or thereabouts. Vice versa for checking rear

Easier still - leave it out of diff lock and with the handbrake still on try pulling away. if it movers its the rear diff or half shafts, if it doesn't then either front diff, half shafts, CV's or drive members. Just use this to prove what it is - don't drive any distance like this!
