how hard is it to change out a broken stud on the front, what all do you have to remove to take the broken stud out and slide the new one in
thanks for your help, kevin
Glad you asked since I was going to post how I changed mine. First of all, I wanted to let everyone know that the front and rear studs are different sizes. So make sure you order the right one. The dealership parts dept had them both for about $3.50 a piece so I bought three - one to replace the front one and two others for front and rear spares in case I break one again. They actually hammered out the old stud to inspect it. They didn't charge me for it either. Since I thought $89 was ridiculous to pay for putting a new one in, I did it myself.
Here's the procedure I used:
1. Take wheel off. (obvious)
2. Take off brake line bracket that's bolted above the caliper. Make sure to take this off first because the brake line will probably bend under the weight of the caliper if you don't take it off.
3. Take caliper bolts off. Make sure to have something to support the caliper since it is HEAVY. I used a jack stand. Jiggle the caliper off the rotor.
4. Take off brake rotor.
5. NOTE: This step was done by the dealer not by me --> Hammer out old stud.
If there's enough thread left I would suggest getting a nut that fits the stud, screwing it in a little and hammering it. Mine was too short to use this method.
6. Insert new stud from the back. It should be fairly easy to pass through. I then used some 1/2" washers(about 5 of them) that I had laying around and placed it on the other side where the stud sticks through. Then I put a lug on the stud and started tightening slowly making sure that the stud was going in perpedicular to the hub. I tightened until the bolt was flush against the back of the hub.
7. Replace the rotor. Check the stud and make sure it sits in the middle of the hole in the rotor along with the others. You might have to hold and rotate the rotor a little until you get it just right.
8. Replace the caliper and tighten bolts
9. Replace the brake line bracket and tighten bolt.
10. Place wheel back on. I noticed that one of the lugs did not go in as easily as the rest and the lug was sitting higher when I hand screwed it in. I think I might have had a slight angle on the new stud I put on. I just jiggled the wheel until the lug fit and tightened.
I took about 30-40 mins(I wasn't keeping track). Hammering out the old one would probably have taken a couple more minutes. It's fairly easy. Just make sure to take your time setting the new stud in and don't rush it.
I took it for a drive and then took the wheel off again. When placing it back on, all the studs were centered perfectly. I guess the stud needed a little more tightening which happened when I put the wheel on.
