Did you send that clip to RW? Their service response time must've improved by now...Hi folks and redwood
I got AWD GT coils
Recently I got sound from rear. Recorded sound see attached.
First look show its somewhere on top hat or rear suspension (redwood unit)
We decided to change it from right to left, and sound moved as well.
So obviously its top hat (oem) or your unit.
We planned try to replace both rear absorber/damper back to oem, so to determine is that top hat or rear absorber/damper.
If that's happening (or the most audible) at low speed/rough-ish road, then in sounds like the rear spherical bushing/bearing binding, where the shock mounts to the suspension arm. A few of us early adopters had it. If you have the metal rear bushing version then spray some lubricant in there to see if it quiets it down for a day or two.
If you have the rubber bushing version, it's possible that the tophat is loose.
