Recently when i have been backing up out of my driveway and cutting the wheel (not locked) it makes a wierd noise like a knowcking or thumping and you can feel it in the car what could this be. tia

 

Need more info... where does the sound, sound like its coming from. The front or the rear???

 

Is it only when you are moving, or does it do it the whole time? I know one of my tires was unbalanced and it made this really wierd kind of "thump" as I turned, consistent with speed, I could only feel it turning on smooth pavement. Rotated the tires and it went away. Can't think of anything else. Most of the steering whines when something is going wrong.

 

Its when moving only and only when im in reverse its coming from the front and you can sort of feel it through the steering wheel.
