Actually, I use to own a Vios, funny is, after they service, there was knocking noise coming out of the suspension, after repair noise even worst!

I just ignore the noise until few years later when it become unbearable...so I took it to a so call Suspension specialist, the workers couldn't find the problem, so the boss himself looked at the suspension..

Immediately notice the antiroll bar bushing cracked...maybe because previously, UMWSC over-tighten all the screws. After changing the bushing at tighten the screw to an acceptable limit, the knocking sound was solved.

Lesson learned:
1. Some of the UMWSC so call technician know nothing about trouble shooting...all they know is tighten all screws and bolts as much as they can, they say only follow standards

2. Sometimes its better to have a so call outside suspension specialist look at the car, they probably can repair the car even better than UMWSC...but trouble is, they can be cut throats too while doing it.

3. Now I own a conti car, and....also got pulling to the left issues and high speed vibration issues....after a few times repair also cannot, most of the similar car owners also complain about it.....but its OK, I can life with it. Nowadays, they dun make cars like they used too...whatever common car
