Yeah it is kind of like that, only way to describe it in words is: digga digga digga digga etc... But last time i had the car serviced i asked them to check the bearings due to a noise that i thought was coming from the right front wheel, but they said that there wasn't anything wrong with the bearing..
There is a little movement but they said that they were ok...
Also while driving there is a whiney kind of noise which comes and goes as well...sounds like it's coming from the right front area..disappears around the 70km mark
