Understanding the Purpose of the Toyota 90311-38014 Rear Differential Oil Seal

The Toyota 90311-38014 Rear Differential Oil Seal is specifically engineered to prevent oil leaks from the rear differential housing.

Without a proper seal, you're inviting metal abrasion, overheating, and ultimately, catastrophic failure that might require costly repairs. But how do you know when it’s time to replace the oil seal?
