I just changed the front shocks ,tie rods and got an alingment, the truck ran great for a while but now have a vibration if go over 55mph or slow down. I notice that the front wheels were not spinning as freely as before and wounder if the brake calipers need to be changed.

 

Do you feel it in the steering wheel, when you hit the brakes?

 

no, it is a constant vibration when the truck go's over 55 or when it slows down without touching the brake. I changed the front and back pads and rotors within the last year.

 

Have the tires been balanced lately? It could have lost a weight.
