Lug Nuts

Has anyone had problems with lug nuts after a blown tire. A year ago we blew a tire and had no problems. This last May I had the bearings packed. No problems until today when I was checking the torque I noticed (4) nuts missing upon inspection I notice the studs were broken off.
At this point we are just starting to look into the problem.
Any suggestions.
Thanks in advance.
Jack

Sounds to me like they were over torqued.

Jack, I'd go back to whoever you used to pack the bearings! I would say they have a rookie there that has no knowledge of the use of an air gun for torqueing the nuts on a Monte!

Proper torquing can only be done correctly with a calibrated torque wrench NOT a pneumatic impact wrench.
I'm willing to bet you're hopping mad about this... I would be.

I agree with the others. There is only one obvious cause for this and it's the people you trusted not knowing what they are doing.

I would be going back to the outfit that did your your wheel bearing pack and do some serious chewing out. New studs at their exspense and free service. That could have been a major problem if you had not checked.

You need to replace all of them. If they pulled 4 in to what do you think happened to the rest of them. I wouldn't even pull the camper until they were replaced. To do so you are begging for serious trouble and you are going to get it.

I would check the torque on the other lug nuts. That would answer the question, how they were torqued.

Hey guys - what is the correct torque foot lbs. I may be over doing mine. I had a wheel run off my unit a few years back and have been anal about keeping them tight every since.

120 foot pounds. First torque to 60 foot pounds and then to 120. Recheck after travelling about 50 miles.

I too feel they were over torqued. As stated by others, the only way to get the proper torque is with a manual torque wrench. They make a product called torque sticks that attach to an impact wrench (between the wrench and the socket) which work pretty well, and some shops swear by them, but they are only as good as the tech that's using them. If the impact wrench isn't set to it's highest setting and in good shape, the torque applied isn't enough. If they happen to pick up the wrong stick, it can be too much or not enough. We use them at our shop, but I check them against a torque wrench periodically, and my guys are well trained in the use of them. We do not use them on trailer wheels though, I prefer the accuracy of the hand held torque wrench.

Hi all....I have a different opinion . The lug nuts where loose...maybe just finger tight....this will cut studs off big time.

I he d a tire shop use the torque stick on my car. They used the wright one, I watched them. It still had over 120 pounds on my lug nuts. I took the car back, they said that couldn't happen until they checked and then we don't know how that happened.

I can pretty well tell you how it happened. Torque sticks that to be checked against the air impact they are used on, at a specific air pressure to make sure they are imparting the correct amount of torque. Once verified, any change in impact wrench or air pressure can also change the torque specs. That's why even though I use them, I still check with a torque wrench for verification when done.
