help

Hello,
About 6 months back I made a u turn and hit the curb. It hit and hit the other side too, so luckily nothing happened to anyone. Unfortunately the wheels and suspension got messed. Since it is a new car and im the only driver in the family, I had no knowledge about cars. I took it to a Honda company and they replaced the tires and rim. They also said they tried flushing out the fluid from suspension. I have no idea what that means. After I took it back I noticed the car was fine, but I heard a little noise on the drivers side, which didnt really bother me. When I stop the car I hear the noise actually. After I realized when I made turns the wheel turned back slowly. I took it back and they said it will cost 1000 something to replace the steering rack. I didnt have the money, so I didnt fix it. Im use to it now and it does no harm. I plan on fixing it after few months when i have the money is it ok? Is it going to create more damage?
thank you for ur response in adance
