I assume so. How would I know it is bad?
The truck had some major work done to it just prior to this noise starting. All fluids changed. Coolant, P/S fluid, brake fluid, trans fluid, rear diff fluid, A/C manifold line replaced and system recharged, rack and pinion replaced. I pulled the serpentine belt and all pullies spin freeley with no noise or binding.
