4-wheel drive models have sealed, non-adjustable front hubs and bearings. There are darkened areas surrounding the bearing races in the hubs, which are the result of a heat treatment process; the darkened areas do not signify a defect.
Check to see the inner cones of the bearings are free to `creep' on the spindle. Polish and lubricate the spindle to allow `creeping' movement and to keep rust from forming.
