How to Tighten Truck Lug Nuts

Tightening the lug nuts on your truck can help to extend the life of your wheels as well as the brake drums and rotors. It is important that you tighten the lug nuts correctly, using the right tools. Follow the steps below to tighten truck lug nuts appropriately.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Torque wrench

Determine Lug Nut Torque

1. Use a torque wrench to measure the lugs on your truck. While a wrench with a needle indicator works the best, use a dial-clicker wrench for these steps.

2. Dial the torque to a foot/lb. ratio that you are certain is below the lug nut specifications for your truck. Attempt to turn the lug nut. If the wrench clicks but doesn't turn the lug nut, your torque is too low.

3. Increase the torque by 5 feet/lb. and test the lug nut again. Continue to increase the torque by this increment until the lug nut turns.

4. Measure lugs on all wheels and find an average to determine the specific torque needed if you don't know the appropriate torque for your lug nuts.

Tighten the Lug Nuts

5. Set the torque wrench to the correct feet/lb. for the lug nuts on your truck.

6. Use a crisscross pattern to tighten the lug nuts. The wrong sequence can cause the brake drums or rotors to warp and fail. For example, on a wheel with four lug nuts, tighten in the following order: top left, bottom right, bottom left, top right.

7. Tighten the lug nuts evenly. Uneven lug nuts can also warp the brake drums and rotors.

Tips & Warnings

• Think of how to draw a star without raising your pencil, using one fluid line. This is another way to imagine the sequence in which you should tighten lug nuts (especially on wheels with five lugs).
• Don't use an impact wrench (or air wrench) because it can overtighten the lug nuts. Overtightening can damage or break the studs.
