I know that many of y'all use Ford F-150s to tow your Oliver, so I thought you might be interested in this issue. About a week ago I had a routine oil change and tire rotation done on our 2017 F-150. When they had finished, the mechanic suggested that I should consider replacing the lug nuts, as they were showing signs of swelling and could prove to be difficult to remove should I have to deal with a flat tire. I checked online and found that mid-2010s F-150 models have two piece lugs, which are prone to swelling, to the point where a standard lug wrench won't fit. Also, the outer piece could detach, making it even more difficult to remove the lug. My mechanic recommended ordering new lugs online, as it would be less expensive than having him order them. So short story long, check your lugs and maybe save yourself some trouble.
