I need to replace a rear wheel stud. Having never messed with the brakes I looked up in the FSM what I was up against for rotor removal.

For caliper removal it states "(1) Install prop rod on the brake pedal to keep pressure on the brake system." I've never had to do this on any other vehicle I've owned. Am I propping the pedal up or down? It says to keep pressure on the system but if you do that wouldn't it make it impossible to remove the caliper? And if you did remove it wouldn't the piston be forced out?

Anybody replaced a stud? I'm hoping once the rotor is off I can just press it out?

Many thanks,

No prop rod is necessary since you are not disconnecting any of the hydraulic brake system lines/hoses.
**Procedure: may not be all inclusive. :wink:

    1 Jack up rear axle and support vehicle with with jack stands for safety.
    2 Emergency brake OFF, transmission in Neutral
    3 Remove wheel/tire assembly
    4 Remove two bolts holding caliper frame to axle
    5 Remove caliper assembly and hang from spring or other fixed point. (do not let caliper assembly hang from rubber brake hose!)
    6 Remove caliper/brake drum. May have to rotate caliper while pulling on it at the same time to work it off emergency brake shoes.
    7 Remove broken stud with punch, air hammer, etc. May have to rotate axle flange to location where it is safe to drive stud out back of axle flange.
    8 Install new stud using a standard lug nut turned upside down or a 1/2"X20TPI nut with a few stacked 1/2" washers on stud using impact wrench to pull stud into axle flange until it bottoms out.
    ------Use new lug nut on stud or studs that was replaced.------
    9 Reinstall components in reverse order of steps above. Be sure and put some anti-seize on all bolts and studs before assembly.
    10 Torque wheel studs using a torque wrench to 85 - 115 ft. lbs.

Thanks WW. I didn't even think to look in the FSM about stud removal but sure enough, it's right there on 22-12.

I'm hoping I can fit some sort of puller I have over it to press it out. I have several different variations, we'll see.

I know the FSM says not to use a hammer, but you can use two ballpeen hammers to remove a bad stud. Done it hundreds of times!
Simply place one hammer on the broken or stripped stud and use a much bigger heavier hammer to strike the smaller hammer.
Striking it a few times will usually push the bad stud right out.
If the stud is broken off flush with the axle flange, use a large punch or drift tool and drive it out with a big hammer.
The best way is to use an air hammer tool if you have one, it will make short work of driving it out.

No matter how you do it, just be sure and wear some safety glasses and gloves while performing this operation. :wink:
