Hi chong, since david called me here I try to know more detail about the problem. Your Vios is NCP42 or the 93?

1. Will the sound appear if you start car car and just drive without turning the steering?

2. Does sound only appear when steering input is given?

3. Does the sound appear everytime you come to a stop example like traffic light and move again?

4. Sound only appear when the car move forward or in reverse also?

Here's what you can do at home, get under your car and have a look at the front drive shaft, then look at the inner CV joint rubber boot. See if the boot is wet or covered in grease. If it's wet means the rubber boot tear already and dirt have gone into your CV joint and cause damage to the joint. If no, then your rubber boot is fine.

Now, get another person to drive the car and replicate the same situation as you mentioned and you stand beside the vehicle to listen to the sound and to find out the sound came from which side. Driver side or passenger side.

FYI, the ABS sensor uses a non contact sensor (proximity type) at the wheels to sense the vehicle speed when the car moves and ABS will only cut in when the ABS module detects a sudden reduce in speed of the wheels from the sensor.

I'm now no longer with Toyota so I'm not associated with them.

About the brake jam matter, this happens only with drum brakes be it for hand brake use or normal use.

Usually the jamming won't be so serious but it only happens if you wash the car at night or park at high humidity area and with the handbrake engage park overnight. Rust build up in between the shoes lining and the drum lining. fusing the 2 together. But with some force you can separate the 2.

The worst case that happen to me before was the rear drum jam at my 206 so hard that it rip the brake shoes lining off from the base because the shoe lining is just glued using epoxy but I think such cases very seldom since shoes lining now some use rivets to secure the lining material.

if you wash car at night, after washing just drive it around to dry up the brakes.

Hmm....then as david mentioned do check the front absorber strut. Maybe can try with the bonnet open, put your hand on the top of the strut then get ur bro to input the steering. you will be able to feel a knock if the kruk sound happens. Last time I have a customer with a NCP42 that has a kruk sound is because the spring moved away from the bottom absorber seat when he turn the steering. What I do is put a rubber sleeves over the bottom of the spring seat and re-tighten the bolts. Problem solved. I'm not sure will this solve your problem because can't test your car.

my customer is after turn steering to left side and go back straight got sound. It happens every time for him when he turn left so I don't know for 100% your problem is same with him. Best is to still let the tech that can drive your car to check since I'm giving info via cyber space only. Just trying to help out
