This was a science project. I literally threw it together at the last minute because I forgot about it, until I got to school this morning. So the quality of it might not be the best.
Step 1: Grab Your Materials
You get all your materials out, these include:
1. Impact Wrench
2.The correct torque bar
3. An air hose
4. A wrench that is the correct size
Step 2: Removing the Lug Nut Covers
The first thing to do is remove the lug nut covers from the tire.
Step 3: Choosing the Correct Bar
Look at the manual, look it up, or ask someone who would know the correct torque of the vehicle you are working on.(Different brands and models of vehicles require a different torque.)
Step 4: Choosing the Correct Bar 2
Put the correct torque bar on the impact wrench and the correct size socket. For the vehicle I have chosen I needed a 100lb-ft torque bar and a 3/4 socket.
Step 5: Tighten
Tighten them as much as they will go. ( You don't have to worry about over tightening because the torque bar will only allow a certain amount of torque.)
Step 6: Replacing the Covers
After you are finished replace your lug nut covers.
You now can put all your tools away and you can drive away in your newly torqued tires.
