The dreaded 'death wobble' can occur with any vehicle with a solid front axle. The only way to stop it is to slow or stop your vehicles. I've experienced it twice with my Equinox and it's not fun. Even with a 45' coach we were shook pretty violently. There are several 'fixes' that can be applied. Jeep designed a $200 work around with a pigtail that needs to be installed. Chevy changed which fuse to pull. I haven't heard of a Ford fix yet. As stated, a bungee wrapped on the steering wheel will prevent it. Put 'death wobble' in the search box above and you'll get lots of reading. I filed a complaint with the NHTSA and while waiting on Chevy to figure it out, I put an eye hook in the floorboard in front of the drivers seat, hooked the bungee to that and thru the steering wheel. Worked great until Chevy came up with their fix. Below is one of the best videos of this issue. Use the bungee method until you check with Ford for a permanent fix.....Dennis
