This viscous coupling reconnects front and rear drive when traction differences occur, eliminating the shudder or loss of rear drive caused by a failed original. It suits Sienna owners and shops servicing 2011-2018 AWD vans.\u003c\/p\u003e\u003ch4\u003eBuilt For Performance\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDirect replacement for OEM part number 41303-28013\u003c\/li\u003e\n\u003cli\u003eSealed viscous design provides progressive torque transfer\u003c\/li\u003e\n\u003cli\u003eSplined interface matches the factory differential shaft\u003c\/li\u003e\n\u003cli\u003eHeat-resistant housing for sustained AWD operation\u003c\/li\u003e\n\u003cli\u003eRestores rear-wheel engagement under slip conditions\u003c\/li\u003e\n\u003cli\u003eBalanced internal assembly for smooth power delivery\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFits These Machines\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003efor Toyota Sienna 2011 AWD\u003c\/li\u003e\n\u003cli\u003efor Toyota Sienna 2012 AWD\u003c\/li\u003e\n\u003cli\u003efor Toyota Sienna 2013 AWD\u003c\/li\u003e\n\u003cli\u003efor Toyota Sienna 2014 AWD\u003c\/li\u003e\n\u003cli\u003efor Toyota Sienna 2015 AWD\u003c\/li\u003e\n\u003cli\u003efor Toyota Sienna 2016 AWD\u003c\/li\u003e\n\u003cli\u003efor Toyota Sienna 2017 AWD\u003c\/li\u003e\n\u003cli\u003efor Toyota Sienna 2018 AWD\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eOn-The-Job Use\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFixes driveline shudder and binding on AWD Sienna models\u003c\/li\u003e\n\u003cli\u003eRestores rear-wheel assist on wet or slippery roads\u003c\/li\u003e\n\u003cli\u003eCommon replacement during rear differential service\u003c\/li\u003e\n\u003cli\u003eUsed on family haulers and high-mileage AWD vans\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecs At A Glance\u003c\/h4\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Number(s)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e41303-28013\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRear Differential Viscous Coupler\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eLocation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRear differential assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch4\u003eGood To Know\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e How do I know if my Sienna needs a new viscous coupler? \u003cstrong\u003eA:\u003c\/strong\u003e Common signs include shuddering during low-speed turns, binding in the driveline, or a loss of rear-wheel engagement when the front wheels slip.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Does this coupler fit front-wheel-drive Sienna models? \u003cstrong\u003eA:\u003c\/strong\u003e No, this viscous coupling is only used in all-wheel-drive Sienna models that have a rear differential, so verify your drivetrain before ordering.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eSlight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.\u003c\/em\u003e\u003c\/p\u003e","brand":"Solid Spare","offers":[{"title":"Default Title","offer_id":50556848767062,"sku":"ZZ3P00515","price":503.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0697\/8460\/0662\/files\/s-l1600_d247f00c-198b-401f-a2da-2ec0d354c626.jpg?v=1790942623","url":"https:\/\/www.solidspare.com\/products\/rear-differential-viscous-coupler-coupling-for-11-18-toyota-sienna-41303-28013","provider":"Solid Spare","version":"1.0","type":"link"}
