Replacing A Wheel Stud: Step-by-Step DIY Guidance - WikiHow

Maybe your like

1 Feed the new stud through the hub opening. Keep the wheel lined up over the “sweet spot” that gave you the space needed to remove the old stud, then simply slide the new stud into the opening in the back side of the hub. The new stud will be a bit loose inside the opening for now, but that will change once you properly seat it into the back side of the hub.[12] X Research source
- Assuming that you picked out a precise stud match—by consulting the owner’s manual, checking the vehicle manufacturer’s website, and/or taking the old stud to an auto parts store—it should slip into place easily.
2 Slip washers or a stud installer over the exposed threads. A stud installer is nothing more than a metal cylinder that slides over the stud threads to facilitate the seating process. It’s fairly inexpensive and the perfect size, but you can accomplish the same task by getting a stack of metal washers that are just big enough to smoothly slip over the threads of the stud.[13] X Research source
- Use a roughly 1.75 in (4.4 cm) high stack of washers to replicate the size of a stud installer.
3 Secure a lug nut onto the stud by hand. Thread one of the vehicle’s existing lug nuts onto the end of the stud, then twist it clockwise until it’s up against either the stack of washers or the stud installer. Don’t use a lug wrench or other tool at this point since you’re more likely to cross-thread the lug nut and get it stuck on the end of the new stud.[14]
4 Tighten the lug nut with a lug wrench until the stud seats firmly. Turn the lug nut clockwise just like you would to secure a new tire in place. As it presses up against the stud installer (or stack of washers), it will draw the head of the stud into the seat on the back of the hub. The stud is fully seated once its head is flush with the back side of the hub—use your finger to confirm this.[15] X Research source
- Once the stud is seated, simply turn the lug nut counterclockwise to loosen it, then unscrew it the rest of the way by hand. Slide off the washers (or stud installer), then reinstall the tire and secure the lug nuts in place as normal. Now you’re ready to hit the road with confidence!
