might be your lower arm...during u turn, does your steering tendang balik as usual or stuck there?
could be either your tie rod end & rack end......common problem in pv6 using 17".
some ppl call the rack end tulang anjing...cos it looks like 1...the tie rod end is connected to the rack end.....they will know wattudu....just jack the car & goyang the tire...if there is free play, the rack end already mkn...
