checking the steering rack bush is easier if u can see it from the top plus no need to spend RM60 which can fuel me to work for around 5 weeks. Start the engine and have someone to turn the steering left and right...no need to turn much 90 degree left and right will do. U peek under the bonet and see if there is excessive movement of the steering rack. Allignment cost will depend on what/how many parameter needs to be adjusted. Without getting on the allignment computer, u will never know.
