When I'm on the road, I don't have a torque wrench, but using one has given me a better feel for how far to push things when using the lug wrench. Now I might use the impact to spin the nut on, but on its lowest setting, and I don't keep hammering - I stop knowing I'm well short of the required torque (or I'll just spin them on by hand). I found I had real trouble assessing just how tight I was getting things. To locate your free Harbor Freight Tools manual, choose a product type below. Then for a while I switched to an impact wrench. I used to use the "two grunts and a fart" method of estimating the proper torque on my lug nuts. just a word of warning to folks to remember to double check. I'm not saying either of these problems were Rangerfredbob's issue. Once a fastener has been over-stressed, it just can't be relied on.
This can happen with an impact wrench or when tightening by hand. It's not difficult to do damage to a fastener by overtightening, and it's not always apparent by looking at it. Too tight is an issue that far too many people ignore. I know they didn't bother to clean off the rust/dirt/crud that was on the mating surfaces prior to mounting. I'm not sure if they just did not tighten some nuts properly.
Worst case was when I got in a jam and had my winter tires put on by one of those "quick-lube" type places when my regular guy was too backed up to get to it. The Camarillo, California-based company offers more than 7,000 varieties of tools on its web site, mail order catalog, and retail stores. Most of the time, things are fine, but occasionally I'll find a couple that are not to spec. Harbor Freight Tools is a retail tool and hardware company that started in 1968, primarily selling through its mail order catalog, which still exists today. Rechecking tightness after a wheel has been mounted is something I've gotten into the habit of always doing: I usually do it after 50 miles or so of driving.
