the ball-joint on lower arm-joint .... ok noted wif tks .... will ask mechanic to check again ... tks.
after months of bz schedule, manage to squeeze some time today and get it replaced;
1. lower arm-joint both side
2. rubber mounting both side
driving, braking, over humps is

but workshop say due to KYB-gas-shock is firmer than stock-shock, therefore might reduce the lifespan of arm-joint & rubber mounting

Have a great New Yr !!
