The steering pulls hard to the right when I let go of the steering wheel.

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your Envoy. If your Envoy pulls hard to the right after hitting a sunken manhole, it's likely that something was knocked out of alignment. The problem could be due to damaged suspension components such as a bent control arm or tie rod. If you're comfortable, you could inspect the steering and suspension parts for any noticeable bends or breaks. Still, I'd recommend getting the car inspected by a trusted repair shop to fully diagnose the problem. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
