My 2003 expedition is very rough on bumps. My suspension almost doesn't absorb any bumps. Also I have vibration starting at 50mph. I got one of my ball joints and 2 bearing changed, but the problem remains. When I got my suspension lubricated, the problem was gone for a couple of days. Need help

Has your car changed in ride height? If yes, it's the springs.
Otherwise have the shocks and their bushings checked out.
You can do a visual inspection yourself. If the shocks are leaking oil or smell like gas when compressed, or the rubber is cracked and hard.

That is probably the gayest Expedition I've seen in a while.
