Superior Protection: helps block dirt, dust, and moisture from reaching the sealed components.
Versatile Range: part of a line offered in a wide variety of sizes to fit domestic and import applications.
The seal body stays stationary while its sealing lip rides on the rotating pinion shaft, retaining differential gear oil and keeping contaminants out. Gear oil weeping around the pinion yoke or fresh fluid on the front of the rear differential are signs the original seal may need replacing; if a failed pinion seal is the cause, this replaces it.
This part cross-references / interchanges with the following part numbers:
1C2Z-4676-AA, 100715V, 18741, 4132923100
Frequently Asked Questions
What does the SS2923 seal do?
It seals the rear differential's pinion shaft. The stationary seal body holds a lip against the rotating pinion, keeping gear oil inside and blocking dirt, dust, and moisture.
Where is this seal located?
It is cataloged for the REAR (rear rearward) pinion position, where the driveshaft yoke meets the rear differential.
How do I know if my pinion seal is failing?
Gear oil weeping around the pinion yoke, or fresh fluid on the front face of the rear differential, can indicate the original seal is leaking. Diagnose the source before replacing.
