Inner Differential Seal Small Type

Set of 2 pieces

High-quality oil seal for mounting directly on either side of the differential carrier. This small seal prevents differential oil from leaking along the axle shafts towards the wheel hub and keeps the lubricant where it belongs: inside the differential.

Material

NBR (nitrile rubber) with steel reinforcement

Application

Front and rear axle

Set contents

2 pieces (complete axle)

Type

Inner axle seal (small type)

Features

  • Mounts directly against the differential carrier
  • Seals the axle shaft where it enters the differential
  • Prevents oil loss and contamination of wheel hub bearing
  • Manufactured from oil-resistant nitrile rubber
  • Suitable for Dana 25, 27, 41 and 44 axles

★ Essential component during any differential overhaul. Replacement prevents costly damage to bearings and drivetrain components due to oil loss.

Application

Front and rear axles on vehicles as listed in the categories where this product appears. Mounting location: inside the differential, directly against the carrier on both sides where the axle shafts enter the differential.

Installation notes

Disassembly of the differential and removal of the carrier is mandatory for replacing these seals. Use a suitable seal driver or homemade pressing device (long threaded rod with bushings) to position the seal straight and fully. When fitting the axle shafts, take care not to damage the seal lip. Always replace both sides simultaneously.

Compatibility

Please note: this is the SMALL inner seal that sits directly against the differential carrier. Do not confuse with the larger outer axle seal located at the wheel hub. This seal fits Dana 25, Dana 27, Dana 41 and Dana 44 axles as used in the relevant vehicle models.

Historical context

This seal is a crucial component of the Dana axle design that has served unchanged since WWII. The original leather version has been replaced by modern nitrile rubber for improved durability and oil resistance.
