41303-28013 Rear Differential & Viscous Coupling Assembly for Toyota Sienna 3.5L V6 2011-2018 41303-28012 41110-45010

This Rear Differential & Viscous Coupler Assembly (Part Number: 41303-28013) designed specifically for Toyota Sienna equipped with the 3.5L V6 engine 2011-2018. The differential is a critical component for Sienna's AWD (All-Wheel Drive) system, responsible for transferring power to the rear wheels and allowing them to rotate at different speeds during turns. This assembly includes the integrated viscous coupler, which automatically engages to provide traction to the rear wheels when slippage is detected at the front, enhancing stability and control in challenging road conditions such as rain, snow, or light off-road situations. Ideal for addressing issues like whining noises, vibrations, fluid leaks, or AWD system failure, this complete assembly saves you time and labor costs compared to rebuilding individual components. Before placing an order, please confirm whether the product is suitable for your vehicle or send us the VIN number for confirmation. If you can provide a photo of your old part or its part number, it will greatly help us confirm compatibility.
