What would help are the specs of your truck. Year, mileage, etc. I'm assuming these are stock components we're talking about??? As already stated it could be a number of things. Shocks would be the first place I'd look. Also, if you're control arm and A arm bushings are worn the bumps will feel more pronounced. At least mine did until I changed them out. The only thing left to change in my truck are the shocks, they are due.
