I was not very clear I realized:
I'm expecting the tires to scrub when the 203 4x4 is engaged and the hubs locked. (just like my 205 does).
However, with the 203 (hubs locked) in 4x4Low no scrubbing happens.
I basically was driving in a figure 8 in the parking lot.
I'm assuming this shift pattern (From

4x4 Low <-- this is where my shifter is for this test
2x4 low
Neutral
