Re: Checked wheel lug nut torque for 130 ft lbs
I just got some new tools. I got a new 3 ton jack; I lift from my Rocky Road Rock rails. After Chocking front and rear wheels on the opposite side and applying the Parking Brake I jack up the entire side from the center of my Rock Rails. I can only recommend this with the rocky road outfitters rock rails (installed correctly) and not other brands. I do not believe Rocky Road has said, in writing, they approve of this. I only know when I did it it worked great. Also, someone besides me damaged the under carriage by lifting in the wrong place. (Photos on a jacking thread somewhere.) No damage occurred with my jack. (Harbor freight 3 ton aluminum). I positioned the jack so the rail contacted only the rubber part of the pad. I will post photos on the Jack Point thread.
I use an impact wrench with torque sticks. I use the 110 ft/lbs stick. I compared the applied torque with a hand held torque wrench. They were very close. With the impact wrench and the torque sticks I count "one one-thousand, two one-thousand" to make sure the torque is correct. I need to set the impact wrench to maximum with the Torque stick for the proper torque. MY testing shows when using a torque stick it is impossible to torque higher than the stated torque on the stick. (Torque sticks also purchased from Harbor Freight.)
I always start the nut by hand(this avoids cross threading); I think I will hand tighten the first two assuring the rim is on the centering ring correctly before using the impact wrench /w Torque stick. (I have custom wheels with plastic centering rings.) I use the Torque stick for removing as well in case I have the setting not on reverse by accident.
I hope someone finds this information useful.
Also, the reason for all this is I just got my first flat tire at 8,500 miles.
