• Seal outside diameter: 4.943 in (125.552 mm)
• Seal width: 2.938 in (74.625 mm)
• Designed for differential pinion seal applications in driveline and axle systems

Detailed Description

FAG designs sealing components to meet vehicle manufacturer specifications, using materials selected for durability and dimensional consistency. The SS3862 is a differential pinion seal intended to help keep gear oil contained at the pinion area while limiting entry of dirt, dust, and moisture into the axle assembly. Its metal-reinforced construction, spring tension, and auxiliary lip support stable sealing performance in service environments where the seal surface and lubricant retention are both important.

This part cross-references SKF 29471 for the same application. If you are sourcing a replacement differential pinion seal for FAG SS3862, verify the bore, outside diameter, and width against the original component before installation. It is commonly searched as a differential pinion seal for axle repair, driveline sealing, and rear axle maintenance on vehicles such as Honda Civic and similar make/model applications where the correct seal dimensions are required.

What It Helps Address

• Gear oil leakage at the differential pinion area
• Contamination from dirt, dust, and moisture entering the axle housing
• Seal wear caused by age, heat, and lubricant breakdown
• Loss of lubricant that can affect driveline operation
• Noisy or dry-running axle components related to poor sealing

Installation Notes and Tips

Confirm the original seal dimensions and sealing style before installation. Inspect the pinion shaft surface, seal bore, and surrounding housing for wear, scoring, or corrosion that could affect sealing performance. Clean the mating surfaces thoroughly and install the seal squarely to avoid distortion of the metal case or sealing lip. For fitment-based searches, use the exact vehicle application and position information from the catalog listing; this part is commonly referenced in searches for Honda Civic differential pinion seal replacement and similar driveline service needs.

Quality Assurance

FAG states that its seals are engineered to meet vehicle manufacturer specifications and are produced with supplier support to maintain FAG quality standards. The SS3862 follows that approach with a material and construction package selected for axle sealing demands and long-term contamination control.
