I change I CV joint and it leaks fluid from where the CV joint connects to the differential?

This is an axle seal, and it needs to be replaced pretty soon. It is not a good idea to let these go too long because the differential fluid is not easily checked to see how much is left.

Here is a video of a different vehicle but this is what is going to need to be performed:

Please see the info below on the axle which will need to come out in order to replace the seal.

Please run through this info and let us know what questions you have.

Thanks
