    2014 - Mileage loss 4A vs 2H

    My 2014 Expedition (107k miles) was in the shop a couple weeks ago to replace four struts and install new front end stabilizer links. After getting the car back, I've got a front end grinding noise in 2H that lasts less than a second under light acceleration, typically 15 - 25 mph. I figure...

    Had an IWE fail in an interesting way (2008 4x4)

    Normally IWE failure on these presents as clicking/popping in 2WD, and shifting to 4A or 4F resolves it. I had the exact opposite, where 2wd was normal but in 4wd the failing side had a loud repeated clunking under acceleration. Turns out the IWE was being pulled into shape by vacuum under 2wd...

    Entire IWE tested/working but CVs/DS spin at 10+ mph

    I'm tracing a separate issue in my 07 EB EL and decided I needed to eliminate IWEs/CVs/Diff bearings, etc from the equation, so I rigged up my GoPro to see what is going on. I knew my IWEs worked (hold vacuum and can spin the wheel only) but the footage revealed that there is indeed some...

    4WD Engaging/Disengaging (IWE operation) in 2019 Expy/F-150/Navigator

    I have a 2019 Max and hear subtle metallic noise and vibration randomly from near my front wheel (They are usually pronounced within first 5 minutes of driving in the morning). From my service visit, I have learned new information to share with you. SSM 48088 - 2019 F-150/Expedition/Navigator -...

    Wheel Hub & IWE

    Have a 2015 EL XLT 4x4 with 106K. Been having intermittent front end/axle shake, generally when 1st start driving and between 20 and 40 mph. Jacked up and checked wheel hubs, FR had some slight wobble (1/2-in top to bottom). Subsequently replaced wheel hub with Moog hub from RockAuto for...
