FAQ
What does the inner axle seal do?
The inner axle seal prevents differential fluid from leaking out of the axle housing while keeping contaminants such as dirt, water, and debris from entering the differential.
What are the symptoms of a bad inner axle seal?
Common symptoms include gear oil leaks near the axle shaft, fluid accumulation around the differential, low differential fluid levels, and contamination of axle components.
Is this a genuine Mopar part?
Yes. The 5086686AB is a genuine Mopar OEM inner axle seal designed to factory specifications.
Will this fit my Ram 2500 or 3500?
This seal fits many 2003-2024 Ram 2500 and 3500 trucks equipped with the AAM 9.25 front axle. Verify your axle application before ordering.
Should both axle seals be replaced at the same time?
Many technicians recommend replacing both inner axle seals during differential service or axle repairs to help ensure long-term reliability and prevent future leaks.
Can a leaking axle seal cause differential damage?
