The actuator malfunction is typically caused by the failure of the hub diaphragm material, which wears out over time from fatigue and ozone degradation. This Dorman OE FIX 4WD actuator kit features an upgraded diaphragm material that is more resistant to wear and environmental contaminants than the factory diaphragm. The kit also features a new vacuum solenoid for precise engagement of the 4WD system when conditions demand. This kit helps restore proper actuator vacuum performance and 4WD locking hub operation. The kit is engineered to match the fit of the original actuator and solenoid for a complete, long-lasting repair.\u003c\/p\u003e\u003ch3\u003eFeatures \u0026amp; Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eUpgraded repair: this 4wd actuator features upgraded diaphragm material more resistant to fatigue and failure\u003c\/li\u003e\n\u003cli\u003eDirect replacement: engineered to match the fit and function of the original equipment 4wd actuator and solenoid\u003c\/li\u003e\n\u003cli\u003eRestores function: designed to help ensure proper actuator vacuum performance and restore 4wd operation when the factory actuator has failed from diaphragm and solenoid degradation\u003c\/li\u003e\n\u003cli\u003eQuality: backed by a team of product experts in the united states and more than a century of automotive experience\u003c\/li\u003e\n\u003cli\u003eLimited Lifetime Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eLimited Lifetime Warranty\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e3.1 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e12 x 5.5 x 5.5 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eDorman\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer Part Number\u003c\/td\u003e\n\u003ctd\u003e600-305\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003e019495546429\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cstyle\u003e\n.product-faq { margin: 2rem 0; }\n.product-faq__title { font-size: 1.25rem; margin-bottom: 1rem; }\n.faq-item { border: 1px solid #ddd; border-radius: 4px; margin-bottom: 0.5rem; }\n.faq-item__question { padding: 0.75rem 1rem; font-weight: 600; cursor: pointer; }\n.faq-item__answer { padding: 0 1rem 0.75rem; }\ndetails.faq-item \u003e summary { list-style: none; }\ndetails.faq-item \u003e summary::-webkit-details-marker { display: none; }\n.related-items-table { width: 100%; border-collapse: collapse; margin: 1rem 0; }\n.related-items-table th, .related-items-table td { border: 1px solid #ddd; padding: 0.5rem; text-align: left; vertical-align: top; }\n.related-items-table th { background: #f7f7f7; }\n\u003c\/style\u003e\u003csection class=\"product-faq\" aria-label=\"Frequently asked questions\"\u003e\u003ch2 class=\"product-faq__title\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails class=\"faq-item\"\u003e\u003csummary class=\"faq-item__question\"\u003eHow do I verify fitment before ordering?\u003c\/summary\u003e\u003cdiv class=\"faq-item__answer\"\u003e\u003cp\u003eCompare manufacturer part number 600-305 against your existing part and your vehicle or equipment.
