Every vehicle owner needs to learn basic car maintenance to deal with situations that may arise on the road. Changing a flat tire is one such essential skill you should master, and it’s hard to do it without knowing how to replace wheel studs. If your wheel studs have become rusted, stripped, or damaged, they can pose a safety hazard. Fortunately, replacing them is a relatively simple process that can be done with basic tools and a little mechanical know-how.
Locate the damaged wheel stud and remove the lug nuts using a lug wrench. Next, use a hammer and chisel to gently tap the old wheel stud out of the wheel hub. Be careful not to damage the wheel hub or the threads.
Now that the old wheel stud has been removed, it’s time to install the new one. Apply a small amount of anti-seize compound to the new wheel stud to prevent it from rusting in place. Then, tap it into the wheel hub using a hammer until it’s flush with the surface. Finally, tighten the lug nuts by hand as much as possible before using a torque wrench to tighten them to the specified torque.
Identifying Damaged Wheel Studs
Visible Damage
Damaged wheel studs often exhibit visible signs of wear and tear. Inspect the studs for any of the following visual cues:
- Cracks or fractures in the metal, especially near the base or threads.
- Bent, misshapen, or deformed studs.
- Corrosion or rust, which can weaken the metal and compromise structural integrity.
- Loose threads or stripped threads, which can prevent the lug nuts from tightening properly.
Loose or Wobbling Tires
Loose or wobbling wheels can indicate damaged wheel studs. Loose studs may not provide enough clamping force to keep the wheel properly secured, allowing it to move or wobble during driving. Conversely, wobbling wheels can exert excessive force on the studs, potentially causing them to bend or break.
Uneven Tire Wear
Damaged wheel studs can affect the even distribution of force and torque across the wheel. This can lead to uneven tire wear, as some sections of the tire bear more weight than others. While uneven tire wear can be caused by various factors, if it manifests around the circumference of the affected wheel, it could be a sign of a compromised wheel stud.
Vibration or Noises
Loose or damaged wheel studs can cause vibration or noises while driving. As the wheel moves or wobbles due to malfunctioning studs, it can create vibrations that are transmitted through the suspension system and steering wheel. Additionally, loose lug nuts or wheel bearings may also contribute to vibration and noises.
