Having just done a lot of work on my front end, I can tell you that it's a PITA to replace that seal. You have to tear out a helluva lot to get at it, and while you're in there it sure wouldn't hurt to replace the inner bearings(I did) since they are pretty cheap, and after you know what this is like, you're probably not going to want to do it again. Be very careful getting your upper and lower balljoints separated. I tore two of the boots on mine, and just ended up buying four new complete units. You pill probably need a balljoint separator(AKA pickle fork) and a bearing press helps a lot too. I know mine were in plenty tight and after soaking them well in advance with PB blaster and beating on them with a 5lb. sledge for quite awhile, they still didn't want to come out. The book is goin to tell you that you need some special tools, but they can be ignored if you have a little ingenuity and some common sense. I would take a good hard look at those CV boots while you're in there. Mine were showing signs of dry rot cracking from the nasty desert I live in. Good luck.
