Using a wheel stud installer typically involves placing the tool over the new stud and using a wrench, often an impact wrench as demonstrated with the Lisle 22800 tool, to pull the stud securely into the hub until it is fully seated.
Understanding Wheel Stud Installers
A wheel stud installer is a specialized tool designed to efficiently and safely pull a new wheel stud into its proper seated position within a vehicle's wheel hub or axle flange. When a wheel stud is damaged or broken, it needs to be replaced. While some might attempt to hammer a new stud in, this can damage the stud, the hub, or the wheel bearing. A stud installer applies pressure to the threads of the new stud, drawing it squarely into its hole until the head of the stud is flush against the back of the hub.
Why Use a Stud Installer?
- Proper Seating: Ensures the stud is pulled straight and fully seated.
- Prevents Damage: Avoids hammering which can harm the hub, bearing, or the stud itself.
- Efficiency: Makes the job quicker and easier compared to other methods.
Step-by-Step Guide to Using a Wheel Stud Installer
Using a wheel stud installer is a straightforward process once you have the right tool for your specific vehicle and stud size.
-
Prepare the Hub:
- Remove the old stud (if broken, you might need to tap out the remnants; if replacing for another reason, it's typically pressed or hammered out from the back).
- Clean the stud hole in the hub or axle flange, ensuring it's free of debris.
-
Insert the New Stud:
- From the back side of the hub or flange, insert the new wheel stud through the prepared hole. Ensure it goes in as straight as possible.
-
Position the Installer Tool:
- Slide the wheel stud installer tool over the threaded end of the new stud on the front side of the hub. The tool typically has a bearing surface that rests against the hub or flange.
-
Add a Lug Nut:
- Thread a lug nut onto the stud over the wheel stud installer tool. This lug nut will be used to pull against the tool and the hub, drawing the stud in. It's often recommended to use an old lug nut you don't mind potentially damaging the threads on, though many modern installers are designed to protect threads.
-
Install the Stud:
- Using a wrench, specifically an impact wrench as shown in the reference for quick and easy installation with tools like the Lisle 22800, or a strong ratchet/breaker bar with a socket matching the lug nut size, begin tightening the lug nut.
- As you tighten the lug nut, the installer tool pushes against the hub, and the lug nut pulls on the stud threads, drawing the head of the stud through the back of the hub.
- Continue tightening until the head of the stud is fully seated and flush against the back of the hub flange. You will usually feel a significant increase in resistance when it is properly seated. Be careful not to overtighten and strip the new stud's threads.
-
Remove the Tool:
- Once the stud is seated, loosen and remove the lug nut and the wheel stud installer tool.
-
Final Check:
- Verify from the back of the hub that the stud head is indeed flush and properly seated.
Using a wheel stud installer, especially with an impact wrench as demonstrated in the reference, makes the process of replacing wheel studs much more efficient and helps ensure the stud is correctly installed, which is crucial for wheel safety.
