Good morning,
The first thing I would check is the tires. Make sure the tires are not worn where there are high spots that will cause the car to ride unevenly.
Did anyone check the tires when it was aligned?
The other thing is the shocks. If they are worn out, it will not stabilize the ride and allow the car to constantly bounce giving you an uneven ride. You should bounce the car by hand and it should only bounce 1 complete time and return to being stable. if it keeps on bouncing, the shocks are worn out.
