Installation
Check the hub face and threaded holes for any rust or imperfections, clean off all corrosion from the hub face/ ring using your wire brush, clean/ chase the threads using brake cleaner, thread chasing tool, and penetrating oil. Once the threads have been chased, use brake cleaner and a clean cloth to ensure NO contaminants remain/ brake cleaner runs clear out of the threads.
Apply brake cleaner to each new stud and wipe with a clean cloth. Leave the brake cleaner to evaporate (around 1 minute).
To test, manually thread one stud into the hub using the short end of the threads. Verify that the stud does not prematurely bottom out inside the hub. If you have any concerns about this, use a pen or a thin tool to measure the usable depth of the stud hole. Ensure that the depth is not less than the length of the stud you are installing. There may be a portion of a broken wheel bolt or other debris trapped inside. Perform this process for each stud hole.
Run a small amount of thread lock on the tip of the stud and approximately 5mm down the smaller threaded portion of the first stud. Only a small amount of thread lock is required on the section of the stud that will be installed into the hub. Don't use an excess amount.
Hand-tighten a stud into the hub. Thread one nut halfway down the stud, ensuring there is room for another nut. Now thread the second nut, butting up against the first nut with the cones facing each other. Use the correct socket to tighten the two nuts together. Now use a torque wrench on the second nut to torque the stud to 32Nm. Perform this process for each stud.
Note the thread lock has a cure time which is dependent on the item used.
Install the wheel, no consumables need to be used. Tighten wheels in a star pattern (the nut diagonally opposite each time). Lower the vehicle and torque each nut in the star-pattern to 122Nm. Recheck after 100 miles after returning to the pits from the track.
Regal Autosport recommends that you replace your wheel studs annually.
