Step 1
Park the car on a flat surface that is level. Position a floor jack under the end of the vehicle with the bad wheel stud. Loosen all of the lug nuts on the wheel while the car is still on the ground. Raise the vehicle off the ground once the affected wheel's lug nuts are loosened. Jack up the vehicle so that the bottom of the tire is at least two inches off the ground.
-
Step 2
Place a jack stand under the axle and lower the vehicle down onto the jack stand. When the vehicle is lowered down and supported by the jack stand, the bottom of the affected tire should be at least two inches above the ground to make clearance for the removal of the tire and wheel assembly. Your access to the axle assembly should be free of obstruction once the wheel and tire assembly has been pulled off of the wheel studs.

Step 3
Remove the wheel stud that needs to be replaced using a hammer to pound it out or a wrench to thread it out of its splined or threaded wheel stud port. Your wheel stud will either be screwed in or pushed into position. For the threaded ports you will use the correct wrench to loosen it from its mounting hole. For pushed-in wheel studs you will be able to hammer the stud out from the front. Spray the wheel stud liberally with penetrating oil prior to attempting to remove the old wheel stud. These studs are prone to corrosion and can become locked into position. Use the correct tools and steady pressure to remove the old wheel stud(s). Because getting old wheel studs out can be difficult, this is recommended procedure to easily remove old wheel studs that need to be replaced.

Step 4
ARP Press-in Wheel StudsMeasure the old wheel stud if it is not broken. You may need to measure a good wheel stud to get the correct sized replacement wheel stud if the one you are replacing is broken. Measuring a wheel stud with a micrometer will give you the best measurements for buying a new replacement wheel stud. You will need to measure the overall length of the stud, the diameter of the threaded shaft and the diameter of the knurl or collar of the bolt directly under the bolt head. Besides the physical dimensions of the old wheel stud, you will need to know the thread type, and whether the threaded knurl is left or right handed. A threaded knurl will either turn to the right or left when loosened. Make note of the direction when removing so that you buy the correct replacement wheel stud.

Step 5
ARP Threaded Wheel StudsContact an auto parts dealer after you have pulled the broken or stripped wheel stud from the vehicle. Online, by telephone or in person, you can buy the right replacement wheel studs using measurements from the old wheel stud, the make and model of a factory replacement, or even by the brand or model of an upgraded axle assembly. The best way to get the right wheel stud replacement is to have your own measurements handy when you contact your wheel stud dealer.
