How to Replace Lug Studs on Drum Brakes

Replacing lug studs on drum brakes is a task that can seem daunting, but with the right tools and a bit of patience, it can be accomplished by you in your own garage. Stub and lug studs are essential for securing the wheels to your vehicle, and if they are damaged or worn out, it’s crucial to replace them to ensure safe operation. Here's a step-by-step guide on how to replace lug studs effectively.

Tools and Materials Needed

Before starting the replacement process, gather the necessary tools and materials

- A lug wrench or tire iron - A jack and jack stands - A hammer or a stud installer tool - A socket wrench - A new set of lug studs (make sure they are the correct fit for your vehicle) - Brake cleaner - Anti-seize lubricant (optional) - Gloves and safety goggles

Step 1 Preparation

First, ensure your vehicle is parked on a flat surface and is in gear or 'Park' mode. Use a lug wrench to slightly loosen the lug nuts on the wheel that you’ll be working on, but do not remove them yet.

Step 2 Lifting the Vehicle

Use a jack to raise the car off the ground. Securely place jack stands underneath the vehicle for safety. Once the car is elevated and stable, remove the lug nuts completely and take off the wheel. This will expose the drum brake assembly.

Step 3 Removing the Drum Brake

In most vehicles, you will need to remove the brake drum to_access the lug studs. There are usually a couple of screws that hold the drum in place. Use a socket wrench to remove these screws, and gently tap around the drum with a hammer if it is stuck. Once loose, pull the drum off to reveal the backing plate and hub.

Step 4 Removing the Old Lug Studs

Locate the damaged lug studs. Depending on your vehicle, you may need to remove some retaining clips or nuts to release the old studs from the hub. Use a hammer to gently tap the back of the stud to push it out through the front of the hub. Be cautious not to damage the threads on the hub while doing this.

Step 5 Installing New Lug Studs

Take your new lug studs and insert them into the holes in the hub from behind. If your new studs have a knurled base, they should fit snugly. If needed, apply a bit of anti-seize lubricant to make future installations easier. Use the hammer or a stud installer tool to gently seat the new studs into place. Make sure they go through the hub completely and are flush with the surface.

Step 6 Reassembly

Once all the new lug studs are installed, it's time to reassemble the drum brake. Slide the brake drum back onto the hub, ensuring it is seated correctly. Reinstall any screws or clips that were removed earlier to secure the drum.

Step 7 Reinstalling the Wheel

With the drum securely in place, it's time to put the wheel back on. Align the holes of the wheel with the new lug studs and push it onto the hub. Begin threading the lug nuts onto the studs by hand, securing them lightly. Once they are all on, use the lug wrench to tighten them in a star pattern to ensure even pressure.

Step 8 Lowering the Vehicle and Final Steps

Carefully lower the vehicle back to the ground and remove the jack stands. Once the vehicle is back on the ground, use the lug wrench to fully tighten the lug nuts to the manufacturer's recommended torque specifications.

Conclusion

By following these steps, you should be able to replace lug studs on your drum brakes successfully. Regular maintenance of your vehicle's braking system is vital for safety and performance. If you feel uncomfortable performing this task, don’t hesitate to seek professional help. Remember, safety comes first! Happy driving!
