Lower front ball joints have to be replaced. Rear rotors and brakes have to be replaced. I have new tires on the truck. When I get on the hwy the truck vibrates,especially the bed of the truck up to around 65mph then it's little vibration. When I brake I get vibration up front. When I'm traveling down the road, the front vibrates from time to time. What is the deal?

 

You have loose parts, its gonna vibrate. Worn shocks can also cause vibrations. Vibration when braking usually warped front rotors.

 

something lose bad ball joints would do that.and I agree with warped front rotors fix as soon as you can.
