Hi all: Here is an excerpt from a web site that I found. "And for a bunch of years, and I don't know exactly how many, Chrysler, on the driver's side of the car, made the wheel nuts left-hand thread, the idea being as you went down the road the wheel nuts would tighten themselves up as opposed to loosening themselves up. So, as your wheel turned, the nut would be turning in the same direction that it would turn to tighten it, and there'd be no risk of having the wheel nuts fly off." Sounds off the wall but that is the answer. Same thing I heard as a kid. Dan Reitz Northridge, CA [Non-text portions of this message have been removed]
