Common Steering Issues This Part May Address

• Power steering fluid leaks from a worn or damaged pressure line
• Loss of steering assist caused by pressure loss in the hose assembly
• Corrosion-related hose deterioration on BMW 740i and 740iL models
• Noise or inconsistent steering operation linked to restricted fluid flow
• Failed original hose connections at the banjo fittings

Installation Notes and Tips

Verify the banjo fitting size, hose length, and routing before installation on your BMW 740i or 740iL. Inspect mating sealing surfaces, related steering components, and fluid condition during replacement to help ensure proper operation after installation. This hose does not include a PS switch port and does not use a bracket.

Quality Assurance
