Knocking Sound

ShutterBug SG

Hi People,

I drive a small Extol van, and lately, over the past months, I have been experiencing this muffled light knocking sound from undercarriage whenever I go over a hump at an angle, or make a turn. I can also feel the knock-knock on my clutch pedal when depressed during a turn or when uneven road rocks my van.

Can anyone tell me what it is? Cause, the people at Sin Tien Seng, can't seem to troubleshoot this, or are unwilling to own up to the flaw.

If there's a knocking sound when steering wheel is turned, esp to near lock, it's usually the drive shaft going up the lorry...... though if this is the case, the sin tien seng people should be able to solve this as this is common for knocking sound when steering is turned....
