No, nothing major. Youll need a new gasket set thats used to shim the ball collar at the back of the tranny. Its not a hard process but it may take a good hour or so. Im not a big fan of the new replacement u-joints as I had one fail on me, so I would suggest looking for an original replacement or a good used one as they are much stronger.
If you dont have a shop manual, nows a good time to get one.
