help rear end noise

[mkturbo3]

i started to get a really bad sound on the way home today it almost sounds like dunking sound. as i go faster and let off the gas pedal i hear the dunking sound faster and as i slow down it gets louder its hard to explain but it goes like dunk dunk dunk dunk and gets faster dont really hear it much on wen im accelerating. i had this sound a few weeks ago but went away and now it came back again. wen i had the car on jacks a while back i had some play in my rear driver side axle and had the same sound just weaker wen i shooked the axle. could this be my axle ?

might be a wheel bearing. jack the car up and spin the while, while it is spinning grab the spring and if you feel a vibration it is the wheel bearing on that side. not uncommon

i will check again for any broken mounts its not a wheel bearing noise. sounds like a big rock on my tire
