How to Replace a Wheel Stud on Drum Brakes

Replacing a wheel stud on drum brakes might seem daunting, but it’s a manageable task for those with a bit of mechanical inclination. Whether you’ve damaged your stud from over-tightening or your stud has simply worn out over time, replacing it is essential for ensuring the safety and functionality of your vehicle. Here’s a step-by-step guide to help you through the process.

Tools and Materials Needed

Before you begin, gather the following tools and materials

- New wheel stud - Jack and jack stands - Wheel chocks - Lug wrench - Hammer or mallet - Socket set - Torque wrench - Brake cleaner - Lubricant (optional)

Step 1 Safety First

Park your vehicle on a flat surface and engage the parking brake. To prevent any movement, place wheel chocks behind the rear wheels. If you’re comfortable with it, disconnect the battery to avoid any electrical issues while working.

Step 2 Remove the Wheel

Using your lug wrench, loosen the lug nuts slightly while the wheel is still on the ground. After loosening, use the jack to lift the vehicle. Once it’s securely elevated, place jack stands under the vehicle for added safety. Now, fully remove the lug nuts and take the wheel off to expose the brake assembly.

Step 3 Inspect the Drum Brakes

With the wheel removed, inspect the drum brakes. Check for any wear on the brake shoes and drum itself. If everything looks good, you can proceed with replacing the wheel stud.

Step 4 Access the Wheel Stud

In most cases, the wheel stud is located in the hub assembly behind the brake drum. If your vehicle has a cover or plate, you might need to remove it to access the studs. Depending on your vehicle's design, you may also need to remove the brake drum. Use a socket wrench to remove the bolts securing the drum, and gently pull it off.

Step 5 Remove the Damaged Stud

Once you have access to the stud, use a hammer to gently tap it from the back of the hub toward the front. In some cases, you might need to remove nearby components if they obstruct your path. Be cautious not to damage the hub as you do this. If the stud is particularly stubborn, applying some lubricant might help ease it out.

Step 6 Install the New Wheel Stud

Before installing the new stud, ensure that the hole is clean and free from debris. Insert the new wheel stud from the back of the hub into the hole. You might need to slightly turn it to align it properly. Once positioned, use a lug nut to pull the stud through the hub. Hand-tighten the nut initially, and then tighten it using a torque wrench according to your manufacturer’s specifications.

Step 7 Reassemble the Brake Components

Once the new wheel stud is securely in place, reattach the brake drum if you removed it. Make sure any clips or bolts are secured tightly. If necessary, clean the brake components with brake cleaner to remove any dust or grime.

Step 8 Re-attach the Wheel

Now it's time to put the wheel back on. Align the wheel with the stud and screw in the lug nuts by hand. Lift the jack slightly to reduce the weight so the wheel is just touching the ground, then tighten the lug nuts with the wrench. After securing them, lower the vehicle completely off the jack stands.

Step 9 Final Checks

With the wheel back on and secured, turn the vehicle on and do a quick walk-around to ensure everything looks as it should. If you have to reconnect the battery, do it now. Drive at low speed for a short distance to make sure everything operates properly. Check for any unusual sounds or vibrations.

Conclusion

Replacing a wheel stud on drum brakes may require some time and effort, but with the right tools and a bit of patience, it's a task you can complete successfully. Being proactive about maintaining your vehicle’s components like wheel studs ensures a safer driving experience. Always refer to your vehicle's manual for specific instructions and torque specifications, and don’t hesitate to consult a professional mechanic if you feel unsure at any stage of the process.
