2003 Expedition Tremble

When I Am Driving Down The Highway, My Expedition Shakes Bad When I Hit A Bump. You Almost Would Have To Stop To Keep It From Shaking (tremble) Please Help

Sounds like you have an extremely loose component in the steering or suspension. I would get it checked out soon.

Follow the previous recommendation before it comes apart and you need a tow.
Go to a good alignment shop or the dealer.
