My 1998 4x4 was in accident. Thought it just needed alignment. Now front tire is bending and front end needs replaced. What does that consist of? Parts?

What does it mean by "front tire is bending"? The wheel is bent? Something is wobbling visibly? First of all, if your wheel is damaged to the point where it is "missing a spoke" and there are only "4 of 5 spokes with lug nuts", do NOT drive the vehicle until this or any wheel like this has been replaced! This is a major safety hazard, and you could have another accident if the wheel fails. It was never meant to be used without the appropriate structural integrity of a complete wheel. Start by fixing any broken or damaged parts and then recheck. A physical inspection by any body shop or mechanical repair shop would be a good start. Once you have the vehicle put together properly, then start looking at the acceleration problem / engine running rich.
