After years of spraying WD40 on them, my driver side seized up. I bought new motors on fleabay for about $70 each also a bushing kit, figuring it would be an easy swap out. Ended up unbolting (very easy) and worked on them on the bench. Like the previous post it was a bear to remove motor. I decided to not use the plastic bushings and bought bronze ones from McMaster Carr. (They had to be drilled and reamed out to match shaft). Applied a generous amount of heavy grease to all fittings ( should be done regularly). Haven't had a stick since. Sorry I didn't take any pictures or make a video (would have been lots of bleeps). I have the greatest empathy for those Expeditions and Navigators out there with dropped boards.
