Might seem like a no brainer, but sometimes we overlook the obvious.
Coming back from the Spring Fling we were on I-97 and all of a sudden the Jeep became very hard to control.
Pulled over and looked underneath for anything broken, didn't see anything.
Third time we stopped I thought to look at the wheels.
I was missing 4 lug nuts off the driver side rear wheel.
Jacked it up and replaced the missing nuts and made it home without further trouble.
I had that wheel off 2 weeks prior working a shock problem and had torqued them down but hadn't driven it until the trip to the Fling so hadn't rechecked them.
Wallowed out the holes on the rim, but it could certainly have had a much worse outcome.
