Suddenly for no apparent reason, i took the car for a drive, after my girlfriend came from work and car was feeling a bit unstable and the ride was harsh. I check tires and pressure seems ok, 36psi, for 205/55/16 tires, i think its ok. But car feels like something is wrong with suspension. I change my springs ans SHocks to TRD shocks and springs 3 months ago. I dont know why the car is doing that, i know i baby the car and never jump over bumps. What can possibly go wrong with the suspension, or is it anything else? Please help, i am afraid to drive the car more than 40mph it feels like its not safe
