ACDelco 15521872 Front Differential Bearing Adjuster O-Ring Seal

The ACDelco 15521872 is a Genuine GM front differential bearing adjuster O-ring seal designed to provide reliable sealing for differential bearing adjusters in select GM vehicles. This precision-engineered O-ring prevents differential fluid leakage at the bearing adjuster interface, maintaining proper lubrication and protecting internal differential components from contamination.

Key Features:

• Genuine ACDelco GM OE part ensures exact fit and original equipment quality
• High-grade elastomer material resists differential fluid, heat, and pressure
• Precision-molded dimensions seal the bearing adjuster to prevent fluid loss
• Prevents contamination of differential bearings and gears
• Direct replacement for worn or damaged original O-ring seal

This seal is a critical component during differential service, bearing replacement, or any repair requiring removal of the differential bearing adjuster. Replace this O-ring any time the bearing adjuster is removed to ensure proper sealing and prevent costly fluid leaks.
