Installation Notes and Tips
Verify the end fitting sizes and hose routing before installation. This assembly includes a PS switch port and is specified for Acura MDX applications without bracket. Inspect mating seals, mounting points, and surrounding steering components for wear before completing the repair. Proper bleeding of the power steering system after installation helps restore smooth operation.
