I have looked at this with the car jacked up as high as I can get it and it looks tight as far as room to work, I was wondering for those of you that have done this in the driveway how hard is it to replace the rear output shaft seal in the driveway. question #2 the gaskets for the shifting lever can I do those from inside the car,thanks for the advise.

topic says it all...

i would like to start by saying i am sorry for the picture size. all the photos of parts for sale are on my photobucket.   http://s1275.photobu...810513905744902             i have a bunch of random things here and i would like to get rid of it all   40 dollars for the fog light pair plus S&H   30 dollars for the koito sealed beam lights plus S&H   make an offer on anything else you need and ill see what i can do plus S&H   climate control has an imperfection in the display.        

Why do people do it? How to do it? And pro and cons on Doing it ?thanks
