I did the flush this weekend and overall it went ... messy. I wanted to say it is imperative to route a 3/8th line extension into whatever container you choose. Since I didn't have a way to connect to my 3/8 hose extension, I just zip tied the return line to the tie rod and aimed it down into a drip pan. This work awesome until I started flushing while turning the wheel. Since the mess was already made by the time I realized what happened, I just continued making a mess until I was through the process. My recommendation: use a cardboard or tarp and make sure you have thought out your line extension and catch pan system!
I was getting some rattling and whine the first couple times I've driven afterward but only for about a half second. I think the noise is gone now but why would that happen? I kept the fluid purges quite short (2 seconds as recommended) but I feel like I must have emptied the reservoir at some point to have it get noisy. Do I need to bleed the system in a particular way? I feel like there is slightly more general whine than there used to be but I'm likely listening more closely.
Thanks for the writeup!!!
EDIT: Pump and fluid were at 105k but making no noise or issues, just wanted new fluid inside.
