5.0 ecoboost Posted April 7, 2023 Share Posted April 7, 2023 My 2014 2.0 eb awd suddenly started making a loud clunk when turning either direction at low speed forward or reverse. Straight line or higher speed no vibrations no noise. It might be the half shaft CV joints but I have kind of ruled it out. The rear joints don't articulate when turning like the fronts. I placed a camera under the vehicle and can see the differential moving (jumping slightly) in accordance with the noise (Clunk). Seems to happen about twice per inside tire rotation. I have dealt with differentials in the past but I can't seem to find information about the guts of this thing. Do these have any type of traction aid, and is there a clutch or viscous coupling between the drive shaft and pinion? Has anyone experienced these symptoms before? 0 Quote Link to comment Share on other sites More sharing options...
WKelley Posted April 8, 2023 Share Posted April 8, 2023 Ford Fusion TT 2.7 rear diff fluid change - Bing video MAKE SURE YOU OPEN THE FILL PLUG FIRST. If you can't get the fill plug off then you can't refill it. Sounds like there is a special fluid with LSD additive, but I am not positive there. If you already hear noises it may be too late. 0 Quote Link to comment Share on other sites More sharing options...
