Funny I work with a Realtor regularly who bought his F150 after seeing mine. When I texted him about my Wrench he let me know he start noticing similar symptoms so he had already traded it in on a Navigator.chasing a vibration/shudder on my 2019 f150 xlt 4x4 extended cab 8' box with 5.0l right now. have 63000 km on it and i did buy extended warenty because of this. since 58000 km it has had rear drive shaft replaced, rear end replaced, left front wheel bearing and a transfer case solenoid/vacum valve as it was howling like i had 35" x 12" wide super swampers on it on stock street tires in 2wd.
