How to Replace Wheel Lug Nuts
(DIY Complexity: Easy / Time: 1.5 hours)

Parts:
1. Lug Nut


Tools:
1. Floor Jack
2. Jack Stand Set
3. Ball Peen Hammer
4. Tire Iron
5. Socket Set


Steps:
Step 1 Secure the vehicle on a solid level surface to ensure that it does not roll or lean when raised.
o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.

Step 2 Break the lug nuts loose but do not remove. Using a floor jack, raise up the front of the vehicle.
o Tip: Using an aftermarket floor jack, instead of the original equipment (OE) jack, can make the job easier and safer. Verify the condition of the floor jack before use.

Step 3 Secure the vehicle with jack stands on both sides for safety before starting any work. Do not rely on the jack to hold the vehicle up while working.
o Tip: The pinch welds or the frame rails are the two best locations for vehicle support.

Step 4 Remove the lugs nuts. Inspect the threads on the wheel studs.

Step 5 Install the new lug nuts by hand making sure they thread properly.

Step 6 Tighten each lug nut in a star pattern. Lower the vehicle to the ground and torque the lug nuts to the manufacturer’s specifications.
