Good idea to re-use axle studs?

Iv striped one of the studs on my front axle so i had to grind it off.
I found some from the same car but they were from the rear axle. I'm not sure if they are the same size front and back but i grabbed them anyway. I grabbed the back one's because the fronts disk breaks and all that ,i didn't have the tools so i settled with what i could.
I like to know if it a good idea to use these? I know some people do this and i know how to put them on but need to ask.

No, the rear studs are not the same as the front. Why in the world would you even attempt to get used studs when news ones cost about $2 apiece. That's ridiculous. They won't be reusable after being hammered out anyway.

Thanks for the reply ,i was looking for something else and came across. I didn't have high expectations for them anyways noticing how the teeth have already been rounded.
Is it a good idea to put the new one's on my self the lug and washer way?
I know the professionals use a hydraulic tool so i'm just wondering if i should just take up shop or not.

They can be pulled in with a lug nut but you stand a good chance of stripping them too. They make a special tool for installing them that grabs more thread and does a better job. You might want to just let a tire shop do it for you. Most don't charge more than a half hour labor.

My two cents: In general from school daze if one goes bad other may too AND if the problem was the stud itself and not the hub it was considered OK to replace just one. If more were needed you replaced the hub!
Some pics of how it's done and not all will be easy on sealed bearing + hub units. Careful inspection that it's good enough is critical and some can be done using good lug nuts to pull the stud into place. If it spun again I'd seriously consider replacing the hub,
Pics speak a thousand words and here's some on this.......
Remember - you are counting on the splines of the NEW (not used) stud to grab good matching splines of the hub plate. If it doesn't look good it should go. Only exact proper replacements should ever be considered.
Here's an example with TWO of five broken and I would be looking for a new or good used axle for that type........
It's not an area to fool around with. When in doubt get a professional eye to to check this or plain let them do it.
Reasons can be from hitting potholes, rust, and some wheel designs put the forces on those studs and not the center hole of wheel to hub. No shortcuts for this,

Thanks for the wealth of information Tom Greenleaf
Well i really don't wan't to replace anything i don't need to of course and like you said i only have one stud so it should be OK.
I can't tell if the bearings are sealed of not i don't know what to look for. I was playing with the caliper trying to get it off the other day but i'm having difficulty's. I got the 2 bolts and 2 elongated washer/studs surrounding them out but it won't come off. It wiggles everything wiggles even disk but no go. I see how it connects and how it could be causing resistance but that's not it i don't think, I think i'm not seeing something behind the caliper?
Any suggestions on how to get this thing off?

I may have missed it but what exact car is this? You have another thread but I don't know if this is that car or what.
To remove the common front brake caliper just to get it out of the way MOST (should say many but not all) will be held in a bracket. You would just slightly compress piston(s) of the caliper back a bit with a "C" clamp (front style calipers) and caliper and the pads should lift off of the rotor. Suspend caliper with a wire, or some creation to the coil spring or whatever is handy so the weight of it isn't on the flex hose - important not to stress that out and take care not to pig tail it putting it back on later.
A bracket is frequently used that held the caliper preventing the rotor from coming off. It is usually attached from the inside with thread locked bolts that will come out - then rotor can be removed if the regular pull off the hub type.
That then exposes just the hub. Most but not all are sealed bearing units but you'll have to state what exact vehicle this is now.
Air tools may be required or a least VERY helpful. As already suggested - a shop should be able to do this in short order AND be able to determine that the hub is suitable for a new stud as already said here.
Keep in mind - just the NEW (no used for studs) is cheap - this is mostly labor and the tools to do it. Many not that much time either. I think there are some that a new stud will not have room to install from back rendering the hub junk and its bearing,

It's a 1998 Plymouth Breeze front wheel drive.
I think i see what you mean about those brackets holding the pads/calipers in. They have these 2 sliding groves for each pad and 2 fixed rail groves for each side of the pads ,2 for each break pad? The break pad groves are working they move with caliper with a few taps of the hammer but to a certain extent it will stop. I have big and small size C clamps to compress the pads but from what i see this will make the pads closer? if i'm even on the right subject?

Oh never mind! I got it off ,all i had to do was pull up no the caliper instead i was trying to put forward because i though the break pad groves were keeping it stationary. Oops!
I also had to cut off the bad stud ,there was no clearance after hammering it out so i had no choice.

I thought it was that car but don't know if you have more than one and we need to be sure.
If the cut off stud was trouble for space to get out a new stud may not work out! Not sure if that hub can come apart for more room or not - just me - I just don't know. Some are pressed together once and that's it.
If this part look up is accurate with the pic if it shows it looks like a new stud might go in from the inside of course. See if pic shows. It is an assy not a pressed in bearing if that info is correct..........

Thats a bummer! I hope it's not so and happy 4th of July!
If the hub did come apart how would i go about this? do i unbolt the 3 main bolts and release the cotter pin?
If it is pressed sealed then that means i will have to get a new hub. So if i have to get a hub can i get one from the wreckers?
I was even thinking of possibly shortening studs so i can make the clearance?

If do have to replace the whole hub with new parts than so be it ,i just hope it's not an arm and a leg.

You can try your own parts look up like I did to get the picture. It didn't list just the bearing which strongly suggests it's put together once! That means it would mean a whole bearing/hub with the studs as an assembly. Most you would need air tools to remove outer nut to driveshaft, then the three bolts that, that pic shows and it would slide off.
If shortening a stud to get one in it still MUST completely use all the threads of the lug nut. That's a bit not cricket to do that. Use no heat to shorten one if you do try that.
It did appear in the pic that there was a slotted area such that when hub was turned you could get a new one in. They are splined in there and made for very tight fit such that they don't spin with the lug nut.
That main axle nut that is large may require a new nut or use a cotter pin - just dunno how they did it on this.
I know folks want to save a buck but if this doesn't go perfectly then the hub may have to go. Get help or whatever -- this is holding the wheel on! When one of five goes it's marginal already. If a second goes the stress on the rest can snap them all at once! An accident over saving a buck just doesn't cut it so make sure it's right,

Yes i was thinking hard about that ,the tempering that is i can't grind it at high speed and if the nuts wont clear the tips of the studs i'm not risking it period but it's worth a try i guess. I don't have air tools yet but iv watched one guy undue the main stud bolt with out a impact wrench. He use the big torsion wrench which i have i just don't have that big a socket or know what size to pick up. It looked hard to get off and the whole car moved but i know i can do it. If the hub has a slot how do i move it to line up the stud hole? I noticed it only moves so far maybe put the rim on and turn it? Could you send a link for the pics and it would be great if i can get detailed info on parts and stuff THANKS.

The hub will turn if you take the transmission out of Park. Rotate it to the point where you have the most clearance. You should be able to just drive the old one out without cutting anything. On putting the new one in, take the stud and grind the round base flat on one side and round the back edge. That should give you enough clearance to get the new one in without taking anything else apart besides the caliper and rotor.

These studs are not perfectly round they already havee a notch on one side less than 1/4 threw end to end i just looked at it and got it moving far enough it was just sticky and the notches in the pic don't work.
Oh and i don't see manage attachments in this forum?
How do you guys post pics?

Pic posting has been a problem with my puter from the get go here. If you can post or put it on a public site then just right click, drop down - click copy, back to your post - right click again and select "paste" and they show up for me but not ones from in my computer's storage??
I can grab anything that's out there publicly posted in a nano second and will never understand why it's so tricky??
Here's a 98 Plymouth Breeze just from anywhere...........

I just skimmed thru this real quick so may have missed a lot..... It looks like you're changing a stud on a Chry?
I just want to add that on a lot of Chry's, they have a "knockout" stamped into the backing plate for stud replacement. If it has one, it will be obvious if you look real close. It's prestamped in the steel plate, so you can knock it out with an air chisel or whatever means you have available.
