When doing our 95, I had to drop the axle on the passenger side to access one of the fittings (not sure if a professional would need to do that, but its what I needed). I'm not sure I would do them myself again, not because of any technical difficulty, but the absolute time sucking tedious boredom it takes to get it done. My worst stumbling block was getting the threads of the small pressure lines started (even with the spheres loosely mounted and allowing movement to line things up). I was not about to risk any cross-threading and having to start over. I hope they have a long, long service life
