Spicer 2-86-418 Double Cardan CV Ball Stud Dust Seal Boot (1310 / 1330 Series Non-Greaseable)

Protect your CV centering assembly from premature failure, lock out destroying road grit, and complete your front driveshaft rebuild correctly with this genuine Spicer Double Cardan CV Ball Stud Dust Cap Seal. Custom-engineered by Dana as a specialized original equipment manufacturer (OEM) replacement component, this high-durability steel-and-rubber boot seal (Part Number: 2-86-418) is designed explicitly to service non-greaseable 1310 and 1330 Series CV centering yoke joints.

On four-wheel-drive trucks and SUVs, a Double Cardan driveshaft utilizes two closely paired universal joints sharing an internal centering ball mechanism to cancel out rotational vibrations at high working angles. This small internal socket joint relies entirely on precision needle bearings packed around a static ball stud yoke. Because it sits completely exposed beneath the chassis, it faces constant exposure to highway salt, abrasive trail mud, water, and road grime. Over high mileage, the factory protective rubber boot splits, rots, or tears. Once the seal is compromised, external contaminants quickly migrate inside to grind down the needle bearings, while the vital internal grease escapes. This causes severe mid-chassis vibrations, a loud, dry chirping noise (often described as "angry sparrows under the truck"), and eventual total binding or destruction of the driveshaft CV head. Installing a fresh, genuine Spicer dust cap seal locks out dirt and preserves your smooth, quiet ride.

Manufactured by Dana Spicer—the industry benchmark in global drivetrain engineering—this round seal features a premium multi-lip elastomeric rubber boot permanently vulcanized to a rigid, high-strength structural steel collar. Measuring 1.83 inches (46.48 mm) in outer diameter and 0.755 inches (19.175 mm) in thickness, the collar is engineered to provide an absolute press-fit over the centering socket yoke, ensuring it stays firmly anchored under intense rotational force. It is an unwritten rule among driveline specialists to always discard and replace the dust boot whenever swapping out universal joints or rebuilding a Double Cardan CV head. Sourcing this authentic OEM replacement component guarantees your high-speed balancing limits match factory blueprints.

Component Highlights:

• Vital CV Centering Protection: Replaces dried, cracked, or missing factory boots to completely seal off delicate internal socket needle bearings from outside moisture and grit.

• Metal-Reinforced Collar: Outfitted with a precision-stamped steel mounting ring that presses tightly over the stud yoke flange, providing maximum retention against high-RPM centrifugal expansion.

• Premium Elastomeric Boot: Fabricated using oil- and heat-resistant synthetic rubber compounds engineered to maintain structural flexibility in freezing temperatures and off-road flexing.

• Genuine Spicer Blueprint Tolerances: Manufactured to the exact dimensional standards utilized on vehicle assembly lines, preventing binding and ensuring seamless articulation.

Drivetrain & Component Specifications:

• Driveline Series Architecture: Fits 1310 Series and 1330 Series CV Drivelines.

• Joint Configuration Style: Fits Non-Greaseable / Maintenance-Free Double Cardan CV Centering Heads.
