I have had a few run ins with wheels coming off, first time was in my 79 cutlass. Cruising down a back road, car seemed to lose its "drive", being that it was having transmission troubles, I figured it finally blew. As we were flat towing the car to see what had happened, the left rear slammed to ground, axleshaft and wheel hit the car a couple times then took off for the ditch. Next, not in a G body but, I was driving my friend's Jeep home from a mud bog/fest, as we were passing through a small town (30mph), left front of the jeep dropped, and out came a 32 inch super swamper (that was fun), luckily it didn't hit anyone or anything. Lesson learned- offroading with over size tires and aluminum wheels is a bad idea (lug nuts have a tendancy to loosen). My malibu, Taking off from a stoplight, got on it a little, as soon as I clicked it in second I heard a nasty noise. I immediatly let off the gas and pulled over. Put the car in park, got out and gave the car a little push......yup, exploded another carrier. While flat towing it home (no I didn't learn my lesson from the first time 😳 ), we took a left hand turn and I saw the axle and wheel start exiting the car in my rear view mirror, caught it in time, was able to pull over before it came all the way out. Called a tow truck after that. :wink:
