So about 8 months ago, I was on the highway and someone had cut me off on the first day of snow of the year. As an inexperienced winter driver, I braked hard and turned the steering wheel to avoid a collision. At the time, I was probably going around 90km/h, and the car spun out. Luckily, I didn't hit a car -- but as I was spinning a good 720 degrees or so, I heard a large banging sound from the back before coming to a stop.
When I got the car to a stop, I parked it a good distance away from traffic and looked at the back of the car -- thinking there'd be significant bumper damage from the loud sound. But instead, the car had no visible damage and the tires/rims were fine.
But as I was driving from that point onwards, I noticed my wheels were off balance -- if I had my steering wheel straight, the car would slant to the right. I had the wheels adjusted to correct the steering problem. Clearly, the wheels had hit the curb hard at some angle and misaligned the wheels.
I had the misalignment problem fixed, and even though the steering is much better, I've noticed my car still felt very unstable during winter driving. It would slip and skid quickly. Now that it is summer time, when I drive faster than 80km/h, I would notice my steering wheel vibrate.
Would anyone here have a guess as to what may possibly be wrong and how much it may potentially cost to correct it?
Since I have been driving since that time (8 months or so), and a mechanic at the dealer did realign my wheels immediately following the accident (if there was a bigger problem than that, he would have noticed it right then and there), I don't believe there's a huge structural risk in keeping it this way. However, it could get worse and I would like to fix it when I can.
Thanks a lot guys!
