Detailed Description

FAG SS2528 is a differential pinion seal designed to seal the pinion area of the axle housing and help maintain proper lubricant retention at the driveline end. The seal construction combines nitrile material with a rubber profile, spring tension, and an auxiliary lip to support sealing performance in demanding axle environments. With precise dimensions and application-specific coverage, this seal is suited for Suzuki Samurai, Sidekick, Vitara, Grand Vitara, XL-7, as well as Chevrolet Tracker and Geo Tracker models across the listed front and rear positions.

What It Helps Address

• Gear oil leakage at the differential pinion area
• Contamination from dirt, dust, and moisture entering the axle
• Seal wear that can lead to lubricant loss over time
• Noisy or dry driveline operation caused by low axle fluid
• Service replacement needs on front or rear differential assemblies

Installation Notes and Tips

Verify bore diameter, outside diameter, and seal width before installation to confirm the seal matches the axle housing and pinion specification. Clean the sealing surface thoroughly, inspect the pinion yoke and shaft area for wear, and replace any damaged components that could affect sealing performance. Confirm whether the vehicle uses a front or rear axle application before ordering.

Quality Assurance

FAG designs seals to meet vehicle manufacturer specifications and works with suppliers to maintain FAG quality standards. The SS2528 is engineered for demanding wheel-end and driveline sealing requirements, with materials selected to help protect axle components from contamination and lubricant loss.
