2002 Dodge Dakota truck bounces

How is it going over bumps with out braking?

Not sure on the description.

But two thought come to mind. First is weak shocks, in which case you can do a bounce test. At each corner of the vehicle, put your weight into it on a downward motion and release it. It should come back up and thats it. No recoil beyond that.

Second is the braking is causing it to lurch forward/downward? The rear brakes may not be working weel and the front brakes are grabbing.
