i have real long wheel studs in my rear end and are kind of a pain to change my tires. i've done it with an air gun but the threads and nut all spin together. anyone else have this problem? how hard are they to change to regular length?

i think i might have one stripped cuz it took me 5 mins to try to get one nut off. can i just replace one?

thanks for your help!

 

You may need a press to get them out, but a BFH* should work. Remove the brake caliper and have at it.

i really don't think i need to use a hammer because when the nuts break loose the studs just dangle in place, does that make sense ?

or should i just leave them in there? what good to they serve?

thanks

 

Sounds like the splines on the other end of the stud are stripped. You will need to replace it. Pull the stud out from the back side and install the new one from the back, then draw it in with a standard lug nut flipped around backwards, so the flat end is up against the rotor or axle flange (so it pulls it in evenly).

You should be able to use an impact to remove the nuts, the stud should not turn at all. If you can't spin the nut on the stud by hand, something is wrong like it's cross-threaded.

 

so how do i go about replacing them? is that nut just temporary to get the stud locked in place? where can i get some of those studs that are that long or should i just go with a standard size? also is it affecting anything the way they are or they just a pain in my ***?

thanks!

 

well good news your not the only one with this problem.i just installed my 12 bolt today and basically stripped every stud(i got the upgraded longer stud).wasnt the studs fault but ****ty lugs.moser sells the studs we need and i think im gonna order a set on monday.i cant recall if our studs are screwed in or pressed in but i think their screwed in bc a coupld of my studs just backed out through the backing plate.gluck.

btw where did u get lugs for your studs?im very interested as to what lug u used.

 

If they are screw-in studs, lock-tite them in to the axles to keep them from coming loose.

 

Appears the Moser uses "press-in" studs???? Another big + for the Strange, with screw in studs, and the flanges drilled and tapped for both 12mm and 1/2" studs - STANDARD

Just to clarify ledfootz post, he got longer Excalibur lugs, and drilled out the end like I told him I did.... but appears the guys in his shop talked him out of running a tap completely through the drilled out lugnut to insure the threads went all the way through the lug.

 

^ this is true

tomm pulling the axles and ordering new studs.

 

after thinking about my situation i dont think the stud was destroyed bc we didnt tap the end of it i think it was destroyed bc it is very possible that some threads got damaged by the bit.the lugs screwed all the way on the stud so the part that wasnt tapped didnt take the stud with it while it was going on.we expanded the whole with a bit so it cleared the studs.i dont think the walls of the non tapped portion touched the stud once.again not all the lugs got destroyed.i think only 2 or 3 studs/lugs got destroyed.next time im gonna use a smaller bit for the initial hole,then flip the lug over and expand the hole with a biger bit then tap it.

 

Does anyone have a part number for the studs i need? is it bad to leave them the way they are?

also how hard are they to change? it doesn't look to difficult but i don't know much about rear ends though so any info regarding the change would be greatly appreciated.

thanks for all your help so far.

 

well are studs arent pressed in.i just isntalled the rear yesterday so its still pretty fresh in my mind what to do.take the brakes off,the backing plates from the stock 10 bolt and slide the axle out.i dunno if we ll have to take off the wheel bearings and that ring we had to press on.im gonna order the studs tomm and have them next day shipped so i can start this on tue and be done with it.if you go on mosers site and click on studs you ll see which ones to get or you can talk to their tech.what lugs did u end up using?

 

the studs do screw in and i got replacment moroso studs that are exact replicas just with an allen head.all my studs are good now and i was able to salvage most of the lugs.turns out the reason why the lugs destroyed 2 of the studs bc the whole that we drilled out wasnt big enough for the end of the stud so it just scrapped against the stud as the part that was threaded ended.btw after you do drill out the tops on the excalibur studs you dont have to tap the ends,thats not what stripped my lugs.

 

I still recommend tapping the Excaliber double length acorn lug nuts. When they tap the threads intially, the end of the tap has a "taper" that allows the tap to slowly increase the depth of the thread it is cutting, as it proceeds through the lug. When the tap finally bottoms out on the closed end of the lug, the threads at that end are not full diameter.... they are reduced diameter because of the taper of the tap. They are reduced in diamter enough to ruin the threads on the stud.

You have to run a tap FULLY through the lug, through the drilled end, just to enlarge the existing threads at the end of the lug, even IF you drill the ends larger than the existing thread diameter.

Not sure why your arguing about this. I spent a lot of time checking this prodedure before I did it. Using a "test" stud, the untapped Excaliber lug damaged the threads. Tapping the threads fully through the end is required.

But, do it your way.

 

im sorry if i came off as arguing about it.i understand what your saying fred and i DO agree with you.im just putting out my experience and what i have done.your way is the right way im not saying its not.you have given me great help in the past including the info about these lugs.im just saying the studs are screw in bc i knew u werent sure if they were or not.at no point am i arguing or going against what you told me to do.i drilled out the tops of the excalibur lugs,expanded the whole with those bits that increases in diameter and tested them to make sure they go over the stud by putting them on backwards which i didnt do the first time which caught some of the studs.either way will work.
