Squealing clutch

So as you all already know mechanics are not my strong point. Got the engine all up and running and bar a fuel leak on the waste return it is pretty perfect. The problem I'm having is just at the bite the clutch is squealing. Seems to e working fine no slip when driving and changes pretty well actually. It was originally seized. It wouldn't change gear until I put transfer box in neutral then selected 1 then but the transfer box back and it seemed to free it up. Just left with the squealing.

If it has been siezed live with it for a bit it may go away. Is the wading plug in place? It my have been through deep water and not had the plug removed to drain it off. A lot of people leave the wading plug out because the rear crank seal leaks but then get water ingress problems.

Likely just to be rust on flywheel and splines run it awile and monitor.

Good that's what I thought.
