New problems.

took my rallysport down the road this morning to wash it and it drove funny. (my tire pressure is fine) but when i go around a curve my steering box seems to have slack in it and it causes the car to weave all over the road. now my dad said for me to park it! that it wasnt safe to drive. could be a bad ball joint, tyrod end or the steering box knuckle worn out. what you guys say? is this something that will cost me an arm and a leg to fix? ( my car drove fine until i put them wider tires on it ) and i drove the car 2 years with out a problem, but i drove it over bumpy roads for a while, that was before i got my truck.

take it in to a suspension shop to get an alignment.. If anything is badly worn, they wont be able to align it and they'l let you know what the problem is
