Rear Upper Ball Joint Replacement

I'm getting ready to replace my rear ball joints. Moog has a problem solver ball joint that they made available in 2013. www.moogproblemsolver.com/_pdf_en1/MOOG_PS_Bulletin_213011_K500208_Eng.pdf (http://www.moogproblemsolver.com/_pdf_en1/MOOG_PS_Bulletin_213011_K500208_Eng.pdf)
I'm looking for any tips or info since this topic is really scarce. This also applies to the Taurus and Sable Wagon 96-05.
Thanks
