203 Part Time Kit question

[franken]

You should have locking hubs on the 205 and they should be unlocked on pavement or a hard surface if in 4 whatever.
Its a gear coupling and will bind. The 4 tires turn at different rates, and bad things will happen. The wheels turn on a different radius do the outers have to travel a different distance to get to the same point. A gear system will bind or break. Draw 2 circles on paper, one larger than the other. Which took longer? A 4x4 has to do both at the same time.

The 203 was famous for eating front driveshafts and eliminating gas mileage.

One reason we love locking hubs, the 205, and 4x4 in general...
