for 9 yo car .. better get it fix outside if cost is your concern. stabilizer bush only cost few bucks per piece. few other possible cause is absorber mounting/absorber/lower arm. can check the price at sparepart shops / lazada / shopee to get an idea how much it cost. SC sure cut throat price ler.

why dont u open the hood n push down the front bumper. get someone to try to identify where the sound coming from.
