Front end grinding noise when 4 wheel drive is engaged, only when I let off gas. Noise will not go away until I disengage automatic lock outs. Differential/auto lock outs? Have already replaced front u joints and wheel bearrings.

Check axle fluid first then have the lockout s checked it may be the thrust washers worn out. See pics
