ok so im comming home after a 4 hour drive from the beach, right as i get near my house i come around a turn and as i straighten the wheel i there a thumping\tumbling kinda nouse from the from of the car...then the shaking starts when im not giving the car gas...i can tell which side its comming from....seems like the middle

ive got pretty much NO ideas on what this is.....describing the noise is kinda hard....
but its a pretty decent shaking

the cv joints are all intact...
lug nuts all tight....

any help would be greatly appreciated

thanx in advance guy
