Hi there.My car on little bumpy road makes ‘gur gur ‘noise. At clean road it is perfect even while on turns. It is 70k driven Suzuki Swift.
To start with check the brake callipers steering joints and suspension bushes. Very often these are brake callipers.
I have kept 2 Suzuki Swift JDM's ,they have steering box problem and Gur Gur noises are 1) shocks,2)Steering box,3) or Underarms bushes check it from a good mechanic.
