Everytime I accelerate I hear a knock/clunk noise from my wheels and I feel it in my truck, it clunks faster with more acceleration and when I apply brakes the clunk goes away and when slowing doing it'll softly knock, I have wheel spacers on it, my truck squeaks when I accelerate like my suspension needs greasing, what do I do!?

 

Check your front shocks. Had similar issue on Right Front. Lower mount was gone...
