its kinda like a rotational grind, as you can hear it going round when going very slow in traffic.
I also hear it when on full lock.. and most of the time when going along at about 30mph i can hear it but sounds like a clicking very fast as the wheel goes round..
also it doesnt do it when accelerating,.....it makes the noise just when coming to a stop say 15mph downwards then when rolling in traffic and also when turning sharply.
