I recently bought a 2005 f250 xlt. If I hit a bump when I am going down the highway my truck will start bouncing really bad. It is a really smooth ride other than that. I've read some forums about problems with shaking, but mine isn't shaking, it is bouncing up and down. It only has 113K miles on it and it is in really good shape. If anyone has any advice I would really appreciate it.
