I am trying to remove the lug nut stud plate to replace the lug nut studs.
I have removed the tire, the rotor, the brake calipher and housing, and the axle nut. I also removed two of the 3 knuckle suspendsion nuts. The last one's head is rounded off.
Cannot get the lug nuts off of 1995 Grand Prix. The first one I tried snapped. I tried spraying with WD40 to see if it would loosen. It's been an hour and nothing. Any ideas?

Re: I am trying to remove the lug nut stud plate to...
If you have the time let it sit overnight or longer, giving it another spray occasionally. It works best when it's given time to soak in. 2 other ways to remove that have worked for me. Get someone to help for this. While putting pressure (to loosen) on a breaker bar w/ socket, have someone give the top of the socket a good whack with a hammer. Try several times, it may break it free. 2nd way is to put socket and breaker bar on and with a couple of firm hits on the end (handle end) of breaker bar, hit in the tighten direction, then do the loosen direction. This can also break it free. Best way is with an air gun. I can't believe how easy bolts come off that seemed impossible when doing it with just human power.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

jack up vehicle, remove tire. knock out old stud with a hammer and punch. put new stud in from back if need be. to draw it up tight.use a lug nut with something under it so when you tighten the nut it brings the stud into position. remove the nut you put on. and replace the tire. good-day! if the brakes and rotor are in the way. you will have to remove them to replace the wheel stud.
It is not recommended to drive it like that. It's not too bad to replace but it depends on your level of mechanical skill, You need to remove the brake caliper and disc and then you can simply knock the remains of the broken stud out with a hammer and punch, To fit the new one insert the stud and then put a large nut over the thread, then fit the lug nut and tighten it to pull the stud into the hub, then simply remove the lug nut and put it all back together.
I have never done one on this vehicle but have replaced many on all other cars over the years, this is what i experienced, the stud will pound out with a good 2-3 lb. hammer, and the new stud and nut will get pulled back through the empty hole by use of a strong impact wrench...start the stud by hand try to pull it as much as you can through the splined hole in the axle flange, install the new nut backwards on the stud screw it down as far as you can then with the 1/2' drive impact wrench on full throttle tighten the lug nut...by doing this you are pulling the stud through the void hole.
Please remeber to use a small amount of axle grease on the new stud and hole prior to installing the replacement stud and nut.
You prbably have to remove the disc brake caliper and brake pads along with the rear disc brake rotor to gain access to the stud, there should be an access hole also allowing you to get behind the axle flange for removal and installation.
Hope this works.
TAKE VECHICLE TO SEARS AUTO CENTER OR ANY TIRE WHEELS BRAKE ALIGNMENT SHOP THEY CAN PRESS OUT THE STUD WITH OUT DAMAGING WHEEL BEARING.AND PRESS YOU IN A NEW LUG NUT STUD.PROBABLY CHARGE YOU $25.00 DOLLARS.
take off tire. remove old stud by hammering it out with a punch. put a socket behind axle plate so as not to break the plate. when replacing, just start stud from back by hand, then use a lug nut to pull it in tight. when tight replace tire!
As far as I can determine, your Elantra has standard rear disc brakes.
The lugs should be attached to the hub, which is attached to the axle. The Disc or Rotor (they're one and the same) slip onto the hub. Oftentimes the disc will seize on the hub from rust. You need to spray the center hole, where the disc goes over the hub, with spray penetrating oil. Also spray the lug stud holes. Then take a (dead blow )hammer and hit the disc around its perimeter. It should then come loose.
The broken stud can then be taken out by hitting the front of the stud with a hammer. You may want to spray the back of the stud where it seats on the hub before taking the hammer to it. Place the new stud through the rear and make sure it's seated correctly.
Clean all parts with brake parts cleaner. The lug studs should not have any lubrication on them.
You have to re-set that "large castle nut" that was removed to its proper Preload Torque. I do not know that spec, but you need to find it out, and how it's done.
Suggest you purchase a Repair Manual for your vehicle(s). It really is the best tool you can get.
I assume that you are referring to the wheel studs and if so you will have to remove the wheel, the brake caliper, the brake caliper stand and the brake rotor. Drive the old stud out with a hammer. Make sure you purchase new lug nuts with the studs. If they are the acorn style, buy one that is not to help with installation. Slide the new stud in the hole from the rear of the flange, install some washers for clearance of the stud shoulder. Install the non acorn style lug nut on the stud backwards. Using a impact gun, pull the stud through. Remove the backwards lug nut and washers.
Remove: wheel, brake caliper & rotor. Drive out the remaining stub with a hammer and punch. Insert a new stud and pull it into place by tightening the lug nut. Before running out of threads, remove the nut, insert a stack of washers or a large nut which slips over the threads without contacting them, tighten the lug nut to seat the stud.
