Detailed Description

Part number 1644660081 is a power steering return hose engineered for Mercedes-Benz ML350 fitment from 2006 through 2011, cooler to pump. Replacing a cracked or leaking return hose helps maintain fluid level and reduces the risk of cavitation and pump damage caused by running low on fluid. The hose is manufactured to OE dimensions and uses reinforced elastomeric construction to handle heat, oil exposure, and pressure pulses in the steering system.

This part cross-references URO-015629 for the same application.

Common Issues It Can Address

• Power steering fluid leaks from a deteriorated return hose
• Low-fluid cavitation in the steering system
• Pump wear caused by running the system dry
• Fitment problems from an incorrectly sized replacement hose
• Heat and oil damage to an aging hose assembly

Installation Notes and Tips

Verify the hose routing and connection points before installation. Inspect adjoining steering components, clamps, and fluid condition so the replacement hose is installed into a clean, leak-free system. Confirm the cooler-to-pump application matches the vehicle configuration before ordering.

Quality Assurance

URO backs this hose with a 24-month unlimited mileage warranty.
