You don't wanna use 4x4 (4hi or 4lo) on dry pavement. Your part-time 4x4 system requires that the tires be able to slip when you turn, otherwise you start binding up the axles until one of the tires breaks loose from the pavement. That's probably the shuddering you feel. Oh, and I just bought those same Yokohama's for my Sierra, they rock... anyway, try engaging the 4wd on gravel or mud and see if you still get the shuddering.
