Hi bro, tumpang thread too. My persona also having same problem. When release your hand, steering adjusted to center, the car pulls itself to the left. The pulling angle is quite serious. I understand that ppl will say it is normal for dragging to left due to the road surface. But this is abnormal as the car goes to the left in just a second, on any speed.
Went to different shops and got the result as below. All are different ans:
1st shop told me is the tyre giving this problem. So I swapped the tyres left right, but problem still exists. --> so, not the tyre problem.
2nd shop figured out that my lower control arm bush (rear bushes, the bigger one) were loosed, so got free play on the steering. I replaced them to those caster kit. for your reference:
PU Caster Bush Wira Satria Waja Persona Gen2 - Car Accessories & Parts for sale in Puchong, Selangor
But after replacement of bushes, the problem still exist.
Went to 3rd shop, told me my caster need adjustment. I have no idea on this because he mentioned caster adjustment will require magat shop / car body repair workshop to do this.
