Part #: 38353AA050. When installing the Differential Cover, it's a great idea to replace the differential gasket. This OEM gasket creates an ideal seal. Warranty note: Subaru of America only warrants parts installed on a car with a matching VIN, and the parts must be installed by a CERTIFIED Subaru Dealership. For example, if you install an STi block in a WRX at a non - certified place, don't expect a warranty claim if something goes wrong. Use your common sense!

Using this Subaru rear differential gasket is easy. When you're installing the differential cover, just replace the old gasket with this new OEM one. It'll make a perfect seal to keep everything in place. Remember, for the warranty to be valid, the part must be installed on a car with a matching VIN and by a certified Subaru dealership. As for maintenance, keep an eye on it during regular car check - ups. If you notice any signs of leakage or damage, it might be time to replace it. And always use your best judgment when it comes to handling and installing car parts.
