Some interesting news and possibly unintended consequence of the pinion brace. This is a quote I pulled from a friend on BookFace who just installed the brace over the weekend here in TX.
"Ok folks, I found a fix for a problem I have had on my 2017 Sling for a long time. I have taken it to the dealer numerous times and they have never been able to correct the loud whine I get when I am driving 50 or above and when decelerating. Well today my son installed the ZZPerformance pinion brace kit on my Sling. How I don't know and don't care but it completely eliminated that whine. Never expected that result, I bought the kit for what they advertised it for, but it also fixed an irritating loud whine I have had for a couple of years." - Richard Wiley
