Wheel lugs?
Alloys on 4 lug hubs. I use it and check torque about every 1000 miles. Never found a loose lug. Got yelled at when getting the wheels balanced. What's right? |

I know adding a lubricant will greatly change the actual torque on the bolt. From what McMark posted, I gather the bolt torque is for dry threads. Putting 108 Ft lbs on lubricated threads is like 140-150 dry torque. Maybe a little more. You could be stretching the bolts excessively. Reason for this is when torqueing dry, a lot of the rotational torque is thread friction, not bolt stretch.
Funny that this should come up as I was wondering what to torque the suspension bolts to and looked it up, but no mention of dry or lubed threads. I took a class years ago and the instructor made it pretty plain that anyone torgueing a bolt dry would fail the practical. What I got from this was to always lube bolt threads, now it seems some torques are engineered for a dry torque spec. If this is so, how is one to know which are OK dry and which need lubricant?
