Haz Posted November 9, 2023 Report Share Posted November 9, 2023 (edited) SSM 52051 - 2019-2023 Edge/Nautilus, 2022-2023 Maverick - AWD - Chatter/Shudder During Low Speed Turning Events Some 2019-2023 Edge/Nautilus and 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 causal part 4000. Supplemental information from 2019-2023 Edge-Nautilus Workshop Manual RDU Diagnostics and Testing document... Axle Fluid Analysis The appearance of yellow or green axle fluid in early mileage axles is a result of yellow marking compound used at the assembly plant to verify gear mesh contact pattern. The marking compound within the fluid will darken some over time. Appearance of milky fluid could be caused by water intrusion. Drain and refill the fluid and retest for normal operation.
