>You're turning to merge. And turning reduces traction. So the combination of turning, accelerating firmly and rain makes the traction situation poor.
I mean making sharp turns with part-time and front axle engaged is sketchy, the result (understeering or oversteering) depends on which wheel breaks traction (because you can't turn without that), and that depends on their individual (dynamic) load, road profile, road condition (including bumps and water) and so on. Accelerating in a straight line is fine though.
