Check power steering fluid - we do this for you! Older vehicles and some new models have a hydraulic power steering pump that is lubricated by power steering fluid. The pump’s reservoir has a screw-type cap that lifts off, so the fluid level can be checked. If the pump runs dry, it can fail and require a replacement costing hundreds of dollars. A few symptoms of a power steering problem are squealing noises when turning the steering wheel or heavy or stiff steering. Newer vehicles have electric power steering; there are no fluids.
