Summary
Some 2019-2023 Edge/Nautilus, 2020-2023 Escape/Corsair, 2021-2023 Bronco Sport, 2022-2023 Maverick vehicles equipped with all wheel drive (AWD) may exhibit chatter/shudder during low speed turning events. This may be due to fluid contamination in the rear drive unit (RDU). Drain and refill the RDU, refer to Workshop Manual Section (WSM) 205-02. Drive for 5 miles (8 km) in stop and go conditions with right and left turns and re-evaluate. If the issue is still present, continue with normal WSM diagnostics. For claiming, use base (4000) causal part.
