    Red face Broken Lugs and Studs

    I was comin home from work today,..Typically a 45min ride, however being that itís a long weekend I was planning on breaking a record,...





    When I finally pulled onto my street I started to hear a clanging sound from the right front tire. I removed the center cap to show that I broke two wheel studs instead,.....I know I am an idiot but if some of you guys could please advise me on how difficult this job is for I have to get on it first thing in the AM.



    Can I find these parts at any AutoZone or Napa? Also,..is there anything specific I should be looking out for as well?





    Any advice would be greatly appreciated.



    Thanks,

    95 STS 98,000

    Re: Broken Lugs and Studs

    I just recently, broke a wheel stud, on my Caddy, and, my wife's Infiniti, in the same day. You can get the wheel studs at any auto parts store. To change them, just hammer the broken ones out, remove the brake components (caliper, rotor, caliper bracket), install the new stud from behind the hub, use a few flat washers, and a lug nut, and turn the new stud in. You will most likely have to use more force to get the studs in, than would be used to torque thw lug nuts to install your wheels. the important part, is to get the wheel stud completely seated. Just look behind the hub, and see that the shoulder on the new stud, is flat against the hub.

    Tony, who put your lug nuts on last? I doubt that the lug was properly torsioned, and probably way too tight. I have seen a lot of shops nowadays stop using their torque sticks for their impact guns, and this would be a plausible cause for your problem.

    Re: Broken Lugs and Studs

    I have to replace three studs on right front wheel hub. I have removed the broken studs (had to hammer the s""t out of them" There does not appear to be enough clearance behind the hub to install the new ones. Anyone have a tip on installing the studs. Would like to avoid removing the hub as I think I would have to replace the speed sensor.

    No need to remove the hub. You may have to rotate it, but there is clearance there. I am not sure of your year, but some hubs, have round access holes in them, specifically for this purpose.

    Re: Broken Lugs and Studs

    Thanks for the reply.1998 Eldorado. I'm working on it right now just took a coffee break. I have it up and have rotated the hub to several positions but no luck. It looks like it isclose when rotated to the right between 2 and 4 o'clock. Just need about a 16th. Have a call into friend I'm thinking about grinding the casting about a 16th. It looks pretty heavy duty. If you have a suggestion I would appreciate it. Thanks

    Re: Broken Lugs and Studs

    Are the new studs the stock length? Maybe they are slightly longer, which may cause an issue. I have never had a problem changing the studs. This is strange.

    You do have the caliper mounting bracket off of the spindle, right? That must be removed to get the new studs in.

    Re: Broken Lugs and Studs

    I have the brake rotor and caliper off.When you say caliper mounting bracked I think you mean the assy that retains the disc pads. The casting that the caliper is mounted to is attached to the strut/spring assemby and the bottom of it is around the drive axel or cv joint. and the tie rods are attached to it. Maybe I'm missing something. The lug bolt is actually slightly shorter as it does not have the 1/4" unthreaded tip. This is a 98 Eldorado right front maybe it is a little different. If i am incorrect regarding the caliper mounting bracket please let me know. Thanks

    Re: Broken Lugs and Studs

    I think it would be a lot easier for you if you take the whole hub and bearing assembly off of the spindle and work on it at a table or something.

    Re: Broken Lugs and Studs

    I think your right about removing the hub. Is the wheel nut a 1 3/8 socket or is it metric. Also do I have to mess with the speed sensor. Somehow I thought if you remove the hub it is affected. Thanks

    Re: Broken Lugs and Studs

    Aside from unplugging the sensor, no. It is a part of the hub assembly.

    I have no idea about the size because I never remember the sizes. I just go with whatever fits better.
