=== Front Replacement ===

The front studs are also fairly easy to replace. To replace them, follow the following steps.

* Loosen the wheel lugs. Do not take them off yet.
* Jack the car up at the correct jacking point and secure the car on jackstands.
* Remove the lug nuts and take off the wheel.
-
Remove the 17mm bolts from the brake caliper and hang the caliper with a rope or wire, keeping the weight off the rubber brake line.

-
Remove the hub dust cap, cotter pin, and then remove the hub spindle nut.

-
Remove the hub assembly and take it to a workbench.

-
Using a hammer and punch, knock the broken stud out of the hub from the front to rear.
