my 4runner has developed a clunk noise recently. I can feel it in the floor and i can hear it as well. it seems to be coming from the driver side rear, but i cannot be sure. i replaced the sway bar end link bushings in the rear, and i removed the drivers side rear shock to see if it was blown and it was good. the truck actually made the noise with out the shock on. i also unbolted the panhard bar and it seems to go away when i shake my truck,

Im lost on the cause!!!

it feels that the rear of my truck moves side to side on the axle. if that makes sense. the body moves side to side, not swaying, but actually left and right movement. but the axle stays. its really weird and hard to explain any ideas
