I just noticed this issue. When I'm going about 30 and take my hands off the wheel it will move on its own from left to right - almost as if one of my tires was hugely out of round. I'm not sure what it could be.

I'm thinking maybe I bent a rim? I did nail a pothole pretty bad one day but that was a couple of days ago.

Any other places I should check? Tie rods?

 

Could be a # of things tie-rod, ball joint, rack and pinion, bent rim, alignment or off balance tire. Check the tire you hit for any bubbles in the tire or dents/cracks in the rim. Jack the car up and wiggle the tire top-to-bottom and side-to-side to see if there is any play. Then check the tie rods to see if they are bent.

 

start with tire pressure.

 

and after tire pressure, check your tire balence.
if you have acces to a machine
also, you can check for a bent rim on the same machine, lol
put it on a lift and make sure eveything looks okay, and nothing bent or broken
