I showed by Ford service manager the thread on this forum that discussed CV joint problems. They said they checked it and there was no problem with the Axel.
What is suspicious is that we had no problem with this until right after we got the truck back from the recall service
We have the lariat hybrid. Previous recalls went ok, but the latest, for engine fire, resulted in truck shaking on acceleration.
Dealer claimed we had a bent rim. Took it to 2 different tire shops. Both shops said all rims were perfect.
Dealer still replaced "bent" rim. Truck still shook on...
