Why is there oil leaking around your rear differential?

Oil leaking around your rear differential could be due to a worn or damaged gasket, which can fail over time and allow fluid to escape. Another possibility is a damaged seal or bearing that may cause oil to seep out during operation. Additionally, overfilling the differential or excessive wear and tear can also contribute to leaks. It's important to address these issues promptly to avoid potential damage to the differential and ensure safe driving.
