Maintenance

To ensure the longevity and optimal performance of your power steering system after installing the seal kit, consider the following maintenance practices:

• Inspect for Leaks: Regularly inspect the power steering rack and associated hoses for any signs of fluid leaks. Address any leaks promptly to prevent further damage.
