Bad noise/feeling after doing rear brakes.

[liftedranger]

I just did my rear brakes on my 1999 Ford Ranger 3.0 all wheel abs. I replaced Drums, Shoes, Springs, Adjusters, Wheel cylinders. Now everytime I hit a bump my truck shakes like a bastard and then ill hit another bump and the truck drives very very smooth like it used too before I did them. It almost sounds like the tires are rubbing on something? I though I blew my rear end. It will not go away, I took the tires off drums off and could not find anything wrong with it, I check the diff fluid and its clean and full, I really really do not want to take it to a dealer/shop. I need this truck to work 100% as its my daily driver. Please any help would be GREAT!
