FAG SS2393 Differential Pinion Seal - Rear

FAG SS2393 Differential Pinion Seal

The FAG SS2393 differential pinion seal is built for rear axle sealing performance on select Ford and Mercury applications. It uses a metal, spring, and auxiliary lip design with polyacrylate sealing material to help keep gear oil contained while blocking dirt, dust, and moisture at the pinion area.

Compatible with 1987-1991 Ford Tempo rear and 1987-1991 Mercury Topaz rear, this seal is specified for vehicles that need a precise differential pinion seal replacement. The FAG SS2393 is sized with a 2.000 in bore diameter, 2.004 in outside diameter, and 1.375 in width for application-specific fitment.

Detailed Description

FAG SS2393 is a differential pinion seal designed for rear axle service where accurate sealing at the pinion shaft is critical. The metal case, spring-loaded sealing edge, and auxiliary lip work together to maintain contact and help protect the differential from contamination while retaining lubricant. For Ford Tempo and Mercury Topaz rear applications, the SS2393 provides the dimensional accuracy needed for a proper service replacement.

This part cross-references Bosch 13562 for the same application. It also references 471268N and 4132393100 in interchange listings. Use the SS2393 when servicing a rear differential on 1987-1991 Ford Tempo or 1987-1991 Mercury Topaz and you need a seal matched to the listed dimensions and vehicle fitment.

Common Problems This Seal Addresses

• Gear oil seepage at the differential pinion area
• Contamination from dirt, dust, and moisture entering the axle housing
• Seal wear that can lead to lubricant loss over time
• Noise or driveline concerns caused by low differential fluid level
• Service replacement for a worn rear pinion seal on Ford Tempo or Mercury Topaz

Installation Notes and Tips

Confirm the bore diameter, outside diameter, and width before installation to match the axle housing and pinion seal seat. Inspect the pinion yoke and sealing surface for wear, scoring, or corrosion before installing the new seal. Clean the housing thoroughly so the seal seats evenly and the lip can maintain consistent contact.

For best results, verify rear axle application details against the vehicle build and compare the removed seal to FAG SS2393 before assembly. Proper installation helps the seal maintain lubricant retention and contamination control in the differential.

Quality Assurance

FAG designs seals to meet vehicle manufacturer specifications and works with suppliers to maintain FAG quality standards. The SS2393 is engineered for demanding wheel-end and driveline sealing requirements using materials selected for durability and application-specific fit.
