A couple of days ago my son hit a deer on the right front of the car. Didn't seem like anything other than the grill, light and hood were damaged. However, after a couple of hours of driving a knocking sound started to show up and it turns out the flywheel/flexplate is cracked.
Any opinions on: 1) Whether the jolt could have caused the plate to flex and crack, or should I just chalk it up to coincidence? 2) Would a cracked flex plate cause the car to run rough at times? This has also started to happen in the last couple of hours of driving.
