Have had alot of wheel problems where i am. I believe they have finally accepted that they have been over torquing. One truck has spoke wheels and never could keep wheels tight. They were crushing the spacer. Rotated wheels on truck i drive (hub piloted) and two days later had a set of duals come loose. He was ramming wheels on with a 1" gun.... The list goes on....
After long enough, i guess they learned? Sometimes it is fun to watch the "experts" in action....

700 is what Petro was starting to do a few years ago for the typical hub/wheel set ups on OTR trucks, don't know if they still do that or not. From what the local manager was telling me, (A good guy who's been there for several years) I guess they got sued pretty good after a truck lost it's wheel shortly after being serviced at a Petro so for awhile (don't know if they still do it) the driver would have to watch and sign off that the mechanic torqued the lug nuts to 700ftlbs. After being sued, I'm assuming Petro did their homework and I'm guessing 700 was the magic number between making sure the lug nuts wouldn't work loose, but not over torqueing the studs. Personaly I always thought that was kinda high since I remember seeing 400-500 stamped on some wheels depending if you lubed the nuts or not. However, since Petro has so much to loose by being wrong and since I have never seen any definitive charts, I just went by what they did. 450 is probably fine if the wheel isn't rusty, however I noticed no ill affects on my truck when they were torqued to 700. Studs never broke, threads didn't show any signs of stretching nor any change in resistance when spinning on the lug nuts, drums never warped, and the seals/bearings never leaked or showed signs of premature wear. I don't know if that policy has changed since it's been a few years. I'm not saying what is right or wrong, I'm just relaying what my experience was.

daytons are 250 -
I have 2 1" guns. one is stronger than the other but I just hammer them on for my hub pilot wheels. I don't hit it so hard on the ball and seat type. Haven't had any come loose.
Have any of you noticed when you get your paperwork from these truckstop shops that it states you have to re-torque the nuts withing 50 miles? Thats how they get out of paying for their stupidity! -
But yeah, whos gonna stop a truck in 50 miles? -
I've never had any come lose as long as they was tightened properly.
-
They shipped it to me fedex, and it came to my home in only 3 days. -
Because of the corrosion at the wheel and hub mating surface. If the wheel and hub are cleaned its not an issue. That stuff can be hard as a rock but you start working it as in going down the highway it turns to powder. Then you have a loose wheel. -
