2000 ford f150, i have a bad hop in the rear when slowing down around 40 mph, turned the rotors and put new pads on, u joints, drive shaft? any ideas?

 

Tires balanced? Any recent excursions where you could have bent your driveshaft? If you have been in any mud, could have caked into your wheels on the inside. Slipped belt in your tires comes to mind too. ??

 

yeah it does it even if i rebalance the tires, and no it hasnt been in the mud or off road really.. it stays clean.. ill be buying new tires sometime soon.. thanks for the ideas.. if you think of anything else let me know..
