I put one of these units in my T way back in 2010 before setting out on a 14000 mile journey all over North America.It worked great and continued to work great for the next 80 to 100 thousand miles.I replaced it with another in 2019 and now I want to rebuild the original one that was so good to me.Is there anyone here with any experience with these . Are there special tools required ? Torque specs ? Centering ? So many questions ,I know but I'd like to see what makes it tick and replace the worn disc
