Low speed + braking howl
Hey,
I have noticed a low pitched howl between 20-30mph that comes up when I take the foot off the gas and gets worse with gentle braking. It almost feels like a regen noise from the BiSG. It also happens if I change it to Neutral. I had the rear diff replaced 2 months ago. Front diff had fluids replaced 5 months ago, no shavings then. Tcase was not done yet. Maybe the generator belt?
Do your L663 have any low speed howl or on braking?
