Hello, I'm Chris.I will do my best to answer your question fast and accurate using the info you have provided. Thanks for visiting Just Answer.
Does this occur more with weight in the bed or with a trailer attached?
Have you tried a lower tire pressure like 65 PSI?
Are you still on stock size tires?
Is the bouce more in the front or rear or center?
Is there any steering feedback at all when this occurs?
I have the same truck except its a V10 F250.
Mine has I would not conside a bounce but it is a harsh ride due to the truck being so rigid and that high tire pressure. I recommend trying a lower pressure i nthe tires especially if your not hauling heavy loads. I would not go below 65 PSI this might help bring the bouch down some for you. The next thing to do is try about 500 lbs in the bed up against the tailgate since the trucks suspension is built and designed to always haul or tow a load. Thats why the suspension in the rear is so much higher. Its assuming the load added will level the truck out and take some of the weight off of the front suspension. Next approach is going top be spending money and replacing the front springs and shocks.
