Product Details

Cardone’s CV Axle Assembly line is engineered around the failure modes commonly seen in original drive axles, including boot cracking, grease loss, contamination, and vibration from shaft runout. The 66-1325 uses a neoprene outboard boot with reinforced bellows where required, pneumatically crimped boot clamps, and quality grease formulated for heat and torque load. This part number is a direct-fit driveline replacement for applications such as Chevrolet Silverado 2500 HD, GMC Sierra 2500 HD, and Hummer H2, and it is also listed for Chevrolet Suburban 2500 and GMC Yukon XL 2500 front axle service. This part cross-references Chevrolet/GMC OE numbers 15868120 and 20875738 for the same application.

Common Problems This Part Can Address

• Clicking or snapping during hard turns
• Grease on the chassis or suspension from a ruptured boot
• Front-end vibration caused by axle runout or shaft imbalance
• ABS warning light after axle replacement when the sensor ring is damaged or missing
• Grinding noise from a worn outer CV joint
