Antoni's wheel stud replacement
We don't always happen to have a torque wrench with us, so overtightening lugnuts to the point
where they break the studs is not uncommon. This is a small write up of how to replace those
broken studs. You can order the studs at most automotive stores and some will even carry it in stock. They are 12x1.5
A good idea would be to bring a lugnut to check the threads.
Tools needed: 17mm, 14mm wrench, 10mm socket, grinder I used this ,hammer, flat screw driver,
rotor pop out bolts, and metal block or wedge.
This is what a broken stud will look like on the front hub.
Remove the break caliper assembly. Take out the pads then there are two 17mm bolts holding the caliper on,
be sure to support the caliper as to not disturb the break line. You now need to remove the rotor. If your rotor does
not come off easily light tap from behind. If it does not budge, there are two threaded holes, find the proper bolt and
drive it in, it will push the rotor out for you.
You will now be able to hammer out the broken stud but before you do, wedge something solid behind the hub to prevent
from ruining the bearing. This is an examble of using a wedge for the rear hub, use a similiar setup for the front.
Unbolt the 3 10mm bolts that hold the dust sheild and manuever it out of the way. The first thing you will realize is
there is no way the new stud will fit in the hole, it is being blocked by the knuckle.
You now need to grind out part of the knuckle until the stud can slide through.
Find yourself a nut to pull the stud through. I used a stock lugnut. It is a good idea to use a washer to prevent any damage.
Also you will find the hub spins once you tighten it. I proped a hammer to keep it from spinning. Make sure you start it straight.
Pat yourself on the back, you have now finished installing the new stud. Reinstall the dust sheild, rotor, and caliper assembly.
The rear is slightly different, there is no grinding but you will need to remove some of the ebrake mechanism. Before any of that, remove
the caliper assembly. There are two 14mm bolts that hold the caliper to the caliper mounting arm. Be sure to take note which bolt when where.
There will be two more 14mm bolts holding the caliper mounting arm on remove those as well. The rotor should now come off. Make sure the ebrake
is not on as it will hold the rotor on. Use the two bolt holes if neccessary to pop the rotor off.
My first wheel I disassembled the entire assembly, I later found out I only needed to remove the lower spring, and adjuster.
Loosten the adjuster by spinning it, then pop the spring off(be careful), then spread the pads(they will still be attached by two pins/caps) The adjuster simple floats and should drop.
Use the previous steps for removing/inserting the stud.
Pat yourself on the back again, you have now finished installing the new stud. Reinstall the adjuster/spring, rotor, and caliper
