The situation is this.
Im trying to find longer wheel studs for my build to work with my KPD beadlocks.
the front diff will use standard sierra knuckles, the rear will be CJ7 hubs.

CJ7 use 1/2 inch studs with 15.875mm knurls
Sierra are 12mm studs with 12.09mm knurls

I've dug around and cannot find a 12mm threaded stud with a big enough knurl to transplant into the hole in the CJ hub.

Can any one see any reason i cannot go to a 14mm stud? or have any other ideas on alternatives.

note: i would rather not use different studs front and rear.

Have you been through the "nice" catalogue?

http://www.niceproducts.com.au/catalogu ... /wheel.php

You can order any of that stuff through repco or similar.

I'm pretty sure Subaru studs are 14mm knurl and 12mm thread, I recall this from when I was looking into my ARP swap.

[tassie jeeper]

if u cant find any just take them to your local mechinist they can mechine them down and tap a new thread into them however this would be costly (or u could drill out the rims for the bigger studs)

[tanshi]

sorry i must not have been very clear.

im trying to track down if possible 12mm by 1.25 studs with a 15.875 or bigger knurl

or

run 14mm studs as i can definitly get the right sized knurl

will 14mm studs cause any issues?

[tanshi]

i guess my other option is to run 1/2 inch studs front and rear

Will a 14mm nut still work as its supposed to on the wheel?

[tanshi]

i guess not, 14mm holes in the wheels. half inch it is

Is welding up the stud holes and redrilling them to suit the 12mm stud knurl an option?

I'm running 14's on mine Tanshi. Nice Products # NS601

[tanshi]

in a rim with a 14mm hole?

[tanshi]

mark i considered welding up the holes but wasnt confident enough in it not failing.

to weld it up is not an issue place a bit of copper behind it and lay into it (the weld material wont fuse with the copper and the copper will fall right off then turn it over and weld the other side.

the main issue is the shape of the holes are recessed and tapered and would be hard to replicate.

[Fatzook]

Truth be told, the holes are closer to 16mm. 5stud F150 rims.

[droverdave]

If the current hole is 14mm, and you want to use a 14mm studd, if anything wont you be needing to make the hole bigger?

and i assume the shape of the chamfer of the hole would need to match the chamfer of the nut?

[tanshi]

the whole in the rim is 14mm. the whole in the hub which hols the stud is 15.8mm

[droverdave]

ah my mistake,

persumably you successfully weld the hub (which if its cast, i woudlnt be comfortable welding something that holds my wheel on)

How are you going to make sure you drill the new holes in the correct spot?

[tanshi]

you would drill through the original disk

[got_bar_work]

Could u weld the holes up and get new ones drilled between the old holes

Why not just leave the current holes and drill between them anyway? Welding the old ones closed may weaken the flange just as much as drilling a second set of holes.

Tanshi if the hole in the wheels is 14mm, and the studs are M14, whats the issue?

[tanshi]

just wondering if they need some sort of clearance? i dont know thats why im asking

[Fatzook]

Right.

I'd say so, but only to make it easier to get the wheels on. Just run a 14.5mm drill through the wheel holes. Should be enough, and won't remove enough of the taper to make any difference to how the wheel nuts pull up.

[neofitou]

You've got get 1/2 thread, with .620 knurl, isnt this what you have already and this will probably fit both of your existing holes..?

Just get longer ones.

I dont get it?

[tanshi]

and then try and find 1/2 inch ones for the front as well. ...

i was looking at all the options.

And you guys flamed the shit out of me for wanting to re drill rims..........

Drilling holes a poofteenth bigger =/= trying to turn a 6 stud rims into a 5 stud.

I'd run the drill bit through the current holes!

[Fatzook]

A hub flange is 10mm thick. A wheel centre is not.

And if you didn't see the issue with re-drilling a 6 stud wheel to 5 stud after all the PCD diagrams you were given, there is something terribly wrong with your eyes.

[tanshi]

looking at this again now that i have my full float rear 90 percent finished

Ive come up with another option and wanted to see if people think it will be strong and safe

If i put the old studs with the 15.875mm knurl in the lathe and centre drill them out to fit the knurl of the sierra stud i can just press them in to the hubs and use standard sized stud.

what does ever one think?

[Bugsta]

I don't quite follow that.

Are the studs you have larger diameter than what you want and long enough? If yes, lathe those down and re-thread to what you want.
