Yes, its a problem in local suzuki alto. it creates idiotic noises on bumps. i think it is due to the fact that pak suzuki has raised the height to approx 1 or 2 inch higher than the Japanese variant and used standard shock absorbers while using high springs which cause them to make tha tha and thup thup noises on bumps. moreover the japanese comes with 14 & 15 inch tyres while local one had 13 inch, so raised height and smaller tires.
Drive carefully, or get a japanses brand set of springs and shock aboserbers. maybe that resolve the issue.
