Torquing Lug Nuts

I looked around and don't find where it tells you if the lug nut is torqued dry or lubricated. Not
even the official users manual tells you. I like to put 3-4 drops of rear end fluid I have in a squirt
can on the threads and seat. Don't like it when I can hear and feel the lug nut chattering as it
tries to slip on the aluminum wheel.

The torque is suppose to be 150 ft/lbs on a 14 x 2.0 threads. I decided on a 130 ft/lbs with
lubrication. I can hardly pull that much in a slow and steady fashion. And I have to go around
twice on the same wheel making sure I didn't miss any of the 6 lug nuts.

Opinions about using 130 ft/lbs ???

Go 150 ft/lbs Rick.
Oil on thread studs.
Pretend your younger.
Use both arms.
Pull 150.
 
I have done the same as you Rick ,with adding a few drops of oil to the threads. I usually recheck the torque after around 50-75 miles and all have been holding. I also don,t like to hear that chatter sound either, makes me think i,m about to snap the lug off..
 
I use moly grease on the threads and have never had any issues with using 100 ft lbs tq,
yeah re-check torque before every trip/use,
but in 50 years no issues
and I always re-fill the bearing buddies, on trailer axles ,
if hauling a car and check tire pressure,
before any trip and if traveling any real distance, carrying a car,
at least once a day

Lincoln Lubrication 1134 Heavy Duty Pistol Grip Grease Gun with Whip Hose
this is a reasonable quality grease gun at a decent price

napa sells this one it looks identical to the one auto zone sells but it cost 2.5 times more

On my old 1990s GM Trucks with 6 Lug wheels I torque to 130 ft/lbs.
Pontiacs and the Corvette I torque to 100 Ft/lbs.

Ford late model trucks 1/2 Ton including Ricks new Lincoln Navigator uses Coarse thread lugnuts.
Seen the wheels come off of them....!
Not by me.
Lugnuts were undertorqued.
Could see the Witness marks on the rim the lugnuts were loose.
Ford uses a Flat washer integrated lugnut.
Has serations to Bite into the alloy rim wheel.
Will not snap at 150 ft/lbs.
Takes 550- 700 ft/lbs to Snap off over torqued with a modern 1/2 inch high output air impact gun like Ingergersol Rand Titanium hammer model or a Snap On Gun.
 
that puts the moly lube thread bolt/nut torque at 100 ft lbs,
as I previously suggested, right in the intended clamping range
