Review on Ford Racing M 1225 B1 Axle Bearing by Marcus Krieger

I bought this kit thinking I might have messed up the driver side gasket and bearing due to a small diff fluid leak while driving. I took everything apart and found no bearing issues and no real sealing issues. I knew what it was doing though, so I pulled out the old one and installed another one from the kit. Regular gaskets differ from the kit in that they have a lip. However, the gaskets in the kit are the correct diameter. After installation and a few track days there are no more leaks. So I can vouch for the seal. The stock will have to be made up for later as my car is only a few years old.
