On Sunday, my car drove just fine, no problems.
On Monday, I did not drive my car.
On Tuesday, my car started bouncing pretty hard once I got up to 50 mph the first time driving it since Sunday. Suspecting the tires were out of alignment, I looked and indeed my front passenger's side tire is visibly pointing a slightly different direction than my front driver's side tire. Specifically, with the steering wheel in a straight position, my front driver's side tire is straight but my front passenger's side tire is pointing out by maybe 5 degrees (the misalignment is visibly obvious).
The only thing that happened to my car between driving Sunday and driving Tuesday, to my knowledge, was shortly before driving my car on Tuesday. There was a snow storm, and the people hired to do snow removal at my apartment complex were taking a lunch break parked right behind my car. Immediately behind my car were two trucks parked perpendicular to my car, taking up the entire aisleway in the parking lot.
When I was getting ready to leave, the truck immediately behind me moved out of my way, but the next truck did not move, so there was no enough room in the aisleway for me to back my car straight out. Thus, I back my car partway out, then turned right to try to plow through the snow on the right side of my stall (there were no cars parked on that side of me, so I had room to drive through the stalls). I got stuck doing this. Some people from the snow removal company came over to help me get my car out (which was nice, considering it was their fault I couldn't back out of the stall properly and avoid getting stuck).
Here's where stuff started actually happening to my car. My tires were spinning out a lot as I revved my engine to try to get traction (I know that's not the right thing to do, but I was stressed in the situation and not thinking well). The snow was quite uneven and my front passenger's side tire was perched higher than the rest of my tires for a minute or so. And one of the workers was pounding really hard around my tires to try to dig out the snow. The front passenger's side tire was the one that got pounded the hardest; I knew he was making contact with the tire directly.
After this, I parked my car in a different stall and then later went driving on the highway, which is when the front of my car started bouncing and I noticed my tires were misaligned.
Were any of the things that happened to my car while trying to get it out of the snowbound stall sufficient to knock my tire significantly out of alignment? If so, which ones? And if multiple, which is the most likely culprit?
Edit: I went to a garage and had my wheels and suspension inspected. They concluded that it was just my wheels were misaligned, they aligned them and now things work well.
