I'm really not sure what's going on either, but apparently there's a service bulletin on this that affects basically every car with this RDU, and shows exactly the part number Boss7t mentioned... The service bulletin is as follows, posting it here in case it helps anyone else in the future. SSM 46965 - 2013-2018 Various Vehicles - Rear Axle Noise – Low Speed Parking Lot Maneuvers – After Extended Driving Some 2013-2018 Escape/EcoSport/Edge/MKX/MKC/MKT/Fusion/Flex/Kuga/Mondeo all-wheel drive (AWD) vehicles may exhibit a clunk, thump, grinding, popping, shuddering or chattering from the rear axle when the vehicle is turning during parking lot or figure 8 maneuvers at low speed after extended driving. Replace the RDU clutch using service kit CV6Z-4A232-A. The Workshop Manual (WSM), Section 205-02 has been updated to include this repair. For claiming, use causal part 4A232 and applicable labor operations in Section 04 of the service labor time standards (SLTS) manual.

Fair enough, I can't argue with that. Thanks again for responding, I'm having the same issue with a 2017 Fusion Sport. I'm not sure if we share the same RDU but this is the best answer I've seen so far, I can't find any info on this specific shudder anywhere else.

Thank you for the response! So was Waldo incorrect in saying that the Fusion doesn't have a viscous coupler? I searched for that part but it looks like it is for a Ford Edge, can't find it anywhere that shows compatibility with a Fusion.

Hi there, I know this is an older post but did you happen to fix this issue?
