What causes a Chevy venture steering to get hard to turn?

Hard steering in a Chevy Venture can be caused by several factors, including low Power Steering fluid levels, a failing power steering pump, or issues with the steering gear or linkage. A worn or damaged serpentine belt can also affect the power steering system's performance. Additionally, problems with the steering rack or alignment issues may contribute to the difficulty in turning the steering wheel. Regular maintenance and prompt attention to symptoms can help prevent these issues.
