I was on my way to work this morning when I noticed a vibration in my vehicle like my tires were not balanced or something. (Half way which means it didn't start until I was well into my trip to work) As I approached a stoplight and speed > 30 my car began to "wobble" from side to side as if I had broken lug nuts or something. I pulled over and checked everything but nothing was broken and all lugs were tight. I got back in and proceeded to work and the wobble continued until I reached 40mph in which the wobble was replaced with the sound of a thumping wheel (kinda like the flat tire sound only not as extreme) which sounded like it was coming from the rear of the vehicle from inside. I need help!!

 

busted axle, busted bearing

reach up under the car and shake your axles
put your hands on either side of the wheel and shake it back and forth
anything happen?
