Knuckle Stud - larger size needed (1 Viewer)

[ChiroFJ]

I previously updated the upper knuckle studs on my '78 FJ40 axle to Magnum ARP HD Knuckle Stud (140171-1-KIT); which are M12. I also added a 5th larger bolt. Sadly I managed to strip the knuckle from most of these and now need another repair. I'm running high steer arms.

Does anyone know what option exists for a larger stud that I could use if I re-tap the knuckle?

Thanks for the input.

TG 6 shooters and arms would be the ticket,

how are you a member for 8 years and have 3 posts?

I'm more of a researcher so I don't write much and usually just ask buddies for advice. The 6 shooters would be great, but I'm short on time and plan to upgrade my complete axles so I'd rather not spend a bunch on something I'm not going to keep.

if you don't want to spend much money, go with another set of small bolt pattern knuckles.

what do your buddy's suggest?

seems to me steering is a major safety item that should be in good condition.

used knuckle to get you by for now until you upgrage...

The used knuckles sound like a plan. Friends had the same ideas; used knuckle or 6 shooter. Cruiser minds think alike. I just didn't know if ARP or someone had another stud option that was larger and would allow another drill and tap. I appreciate the feedback.

I don't know if it can be done with small pattern knuckles, but either M14 or 9/16 would be the next size up.

What happened that you tore out 4 ARP studs and a 5th bolt?

I read that article at Roundforge. I like my ARP studs, but the nuts are lacking when compared to the hardened locking nuts they offer. A locking nut makes so much sense, but this eluded me before reading this.

The thread damage occurred in Moab and I obviously wasn't vigilant enough on the torquing and must have missed it at some point or I wouldn't be in this situation. After adding the 5th bolt I hadn't had any issues for a good 5-6 years, but it caught up to me.
