Should I be worried if I hit a curb?
Hitting a curb hard enough can shift your axle and wheel shaft into the transmission. Even a slight jolt to the case can do harm. If you run over a curb and scrape the bottom of your car, it can even disconnect linkages and cables from the transmission case housing itself.
How fast do you have to hit a curb to cause damage?
Hitting a curb at speeds of just 5–10 mph is enough to cause significant damage. Even if the impact feels insignificant, you should still pull over to assess the damage. Check the tire, especially the sidewall, for damage.
What to look for if you hit a curb?
- Check tires/wheel for any obvious damage. Look for cuts, scrapes, or chips out of the wheel or tire.
- Check under the car for any obvious/visible damage. If you see parts hanging low it could indicate damage to tie rods or control arms.
- Check for steering problems.
