On Thursday afternoon I drove to Sarver with an elder to have communion with a shut-in. On the way back I suddenly started hearing an alarming knocking sound from direction of the left front wheel. From that point on I drove very slowly back to Tarentum.
I did not know what the sound was, but whatever was wrong sounded very expensive.
At my earliest opportunity on Friday I got the car to a garage to be checked out. I sat in the waiting room unsure what the news was going to be.
Eventually the mechanic came back and gave me the bad news: the wheel was falling off. The good news was that it was only caused by loose lug nuts, that the wheel had not fallen off, and that they had fixed it by retightening all the lug nuts.
It is still sinking in to me that I had been close to having a wheel fall off, and I easily could have been driving at highway speed when the failure occurred.
