thx!
So replacing the seals is pretty straight forward correct? Just pry out the old ones without scratching the diff. Press in the new ones and thats it? No extra parts needed besides the Seals?

Thanks.

what else besides the seals is needed? (ie. clips, dust boots, etc.)

Theres a spring clip that comes installed with the new seal. When your removing your old seal make sure the old spring comes out as well.

do you have to drain the diff fluid before you change out the seals? I mean common sense says yes, but eh.. never did it before.
