My 2002 F150 squeak when i begin to drive. its only when i start to drive or when i slow down. What could it be? Is it Breaks or seals?

 

Good possibility it is u-joints. They can squeak or click.

 

its a loud squeak. not so much a click. if it is the u joints whats my solution

 

when i put it in reverse i do hear a clink

 

Replace them. They have dried out and the bearings are being turned into dust. And it does not have to be both a squeak and a click from u-joints. It could be either. You also did not say whether you have a 4x4 or not. If you do, it could also be the CV joints on the front axles.
