Dont be a wise guy...your wheel studs will break eventually. It happens. Anyways, this is what you do when it does.
Read my DIY on brake pads so that you are familiar with the axle before proceeding (http://forum.g35nyc.com/showthread.php?t=831).
1/2 Inch Drive Ratcheting Socket Wrench and Breaker Bar
-12mm Socket or ratcheting wrench
-Open ended wheel lug
-Bungee cord (optional)
-Safety Jack Stands
-Wheel studs. Can be purchased at ANY autostore for about 2 bucks each
On to it.
- Jack up vehicle and remove wheel
- DO NOT set parking brake IF your doing rear wheels
- Remove Caliper
Refer to my brake pad DIY...loosen both brake caliper bolts but remove only one - swing up the caliper and remove the two pads. After the pads are removed, remove the second bolt on the caliper and either hang the caliper or rest it on the A arm where there is no pressure on the brake line.
- Remove Disk Brake Rotor
Removing the rear rotor is difficult:
After you remove the brake caliper, you will need to remove the brake caliper bracket which is secured by two bolts to the axle knuckle and holds the rotor onto the hub. Once these two bolts are removed, you can slide the rotor off the wheel studs. - - you will need a lot of leverage to get those two bracket bolts off. I suggest a long but thin breaker bar and a shallow socket 19mm.
Once the bracket is removed, the rotor should slide off. If the rotor doesnt slide off...tap the rear of it gently.
Alright...your looking at your exposed hub and wheel studs. Inspect them...you can see that the wheel studs are simply pressed into the wheel hub. You must remove the broken studs first
Alright... remove the stud from the hub. You might have some difficulty getting the NEW wheel stud back into the hub...try rotating the axle so that you can get the long stud around the parking brake mechanism. You can do this by raising the opposing axle.
you will now need to press the stud into the hub. Do this with an open ended lug and a good ratchet. just put the open lug on, and tighten as if you are putting on your wheels. this will pull the stud through the hub.
once the stud is all the way in. your finished.
now put everything back where you found it.
I replaced two studs on that wheel for this job. They broke b/c I was using wheel spacers in the rear. Total cost for this job was something like $3.80 for the new wheel studs. Took maybe 30 minutes to perform if not less.
go spend the money you just saved on a tank of gas.
