Plz do visit to Ustad Mohayyudin. His workshop is situated behind Auto Plaza. He is expert in suspension works. And costs depends upon the condition of ur car's suspension, but it will be around 10k-15k max.
thank you dear for your reply, my friend suggest me to replace shocks instead of repair, what kind of shocks available in the market.? like air, or oil type.
yeah, he suggested u right. Get ur shocks replaced. U can easily get a pair of shocks for around 3k from auto plaza, but first do visit some mechanic then he will guide u further upon inspection. And shocks in our hondas or toyotas are filled with oil not air type.
