I completed this on Father's Day during 3 hour afternoon nap time. By far, the hardest part was removing the rear-most bolt holding the AHC tubular guards in place. I apparently did not have the correct combination of fittings to easily reach it. I eventually managed to drop it on the driver side only to realize that you can take all but the rear most bolt out and drop/slide the tubular assembly off to the side to facilitate the removal and installation of the globes like I did on the passenger side.
@grinchy @TeCKis300 how the hell did you reach it?
Like
@TeCKis300 suggested, my cordless impact did a great job; however, my lack of a quality impact rated socket did round off nearly all of the existing globe hex-heads. Fortunately, my 14" Knipex Cobras were enough to loosen and remove the globes. I suggest the purchase of a tightly fitted impact rated 21mm socket without internally tapered chamfers on the apexes of the hex to ensure proper engagement on the rather short stub.
I went from DSF/DSR/PSF/PSR doing 3 complete bleed and purge cycles per corner. The DSF took the most cycles to see fresh fluid come out due to its distance from the reservoir. I jerry-rigged a funnel that hung from the gas cap to keep the reservoir full of fluid. I received no AHC errors during the work and the pump kicked on re-pressurizing the system and lifting the unloaded corner each time.
Like last time, I was unable to evacuate any of the old fluid out of the reservoir - even after the removal of the inline filter screen. I simply diluted it with fresh fluid and flushed a total of 5 quarts through the system. The old fluid was purple/brownish after ~50k miles of street/mom duty. The original fluid was slightly darker when I changed it at 70k miles 4 years ago.
Overall, the ride is slightly improved. Perpendicular seams in the road are not as jarring as they were before and there is a more noticeable difference between Comfort/Normal/Sport settings. Placebo or not, it feels slightly more stable at highway speeds in excess of 90mph. I think one of the most noticeable differences is when idling forward and braking - there is no longer any bounce on the front end. Further, brake dive appears to be less as well. Dampening appears to overall be slightly better.
FWIW, the 2020 LX, even with 21s, still feels like it rides smoother than the 2014 with 120k miles. The Michelins on the 14LX are approaching 5 years and 60k miles so this may be a contributing factor.
PS - proof a 200 can withstand salt if cared for. Woolwax is an amazing product.
