A while ago i hit a kerb and damaged my wheel the wheels repaired and everything seemed ok , but my steering sits of centre which i never used to do , and steering shakes quite bad when driving think ive damaged something but everything looks fine underneath , nothing out of the ordinary so what could it be sometimes i think the wheel sits out at the bottom a bit really not got a clue with steering comopnents and stuff

Any help would be appreciated on what could be wrong
