Oh well, I managed to drive my car onto a sidewalk going at some speed. It hit about a 45 degree angle with the right wheel on the sidewalk and the left wheel still on the road. No damage on the outside.
I've now noticed a ticking sound/feeling when I turn the wheel, about six to seven ticks when doing a u-turn. Also while on the freeway, there's a periodic, but constant, low hum and whine... probably matching the wheel rotation. Strangely, the wheel alignment appears fine. It's a lowered car.
What's the probable damage and about how much would it cost to fix, before I bring it into a shop? Thanks.
