2003 Chevy Impala what can it be?

When you say "I can't move my front passenger tire", do you mean that you turn the steering wheel but that wheel doesn't move? What about the driver's side wheel?

If your wheel has moved out of its normal position (weather the steering wheel moves it or not), then you could've broken a tie rod, control arm, hub/steering knuckle and/or axle.

Unless you're a mechanic, then there's absolutely nothing you could do other than take it to a shop. If you want to jack up your car and remove the wheel, you can describe to me everything you see. That way I could give you an idea of the work and prices you'll be facing.

At least you'll be armed with some ammunition in case you run into a dishonest mechanic. Which there are a hole lot of out there!

Yes, that's your tie rod. And if you hit a pothole hard enough to snap that metal bar in half, then you definitely bent something else.

You'll have to take it to an alignment shop. Sorry. But make sure you find one honest enough to give you a free estimate. Then you could get back with me with their repair order and prices. I'll let you know if it's a fair deal.
