Knuckle Studs - Page 2

peesalot · 07-28-06, 08:30 PM

Well I have been thinking alot bout the 6 stud knuckle. It is really a long road to a short answer. The dana 60 king pin style axle uses 4 bolts/ studs also. IMO the dana 60 has more scrub force which means more force on the same 4 studs. At a 1/2 " stud they do well , with the 9/16 they do well. It would follow that the studs on Toyota need to be upsized. I realize it causes the arm to be redrilled and countersunk but thats is cheap.

Red locktite isn't that tough to remove.
Hit whatever you're taking apart with a propane torch for a couple of seconds, it doesn't take long, and it will come right apart.

Hi Everyone,

Thought I would resurrect this thread for a question I had. I have been out wheeling a couple of times since the install and noticed these come loose easier than the stock ones I had. I have been torque'n them to 90 before I go out and notice I had to retorque them at lunch. Has anyone else seen this? Do I need to torque them down more?

Thank you,

how tight are you torquing them to?

I crank the living hell out of them..

Thank you,

I would suspect that the threads in the knuckle housing are distorted....

ARP Torq numbers

"Knuckle stud nuts should be torqued to 110-120 ft-lbs
Hub stud nuts should be torqued to 28-30 ft-lbs.
Both studs should be installed snug into the hub or knuckle, only the nut should be torqued."

I have found that the toyota studs with the torx heads on them aren't as strong as the old style factory ones . I've broken both , now I'm using ARP's and they seem to be holding up .
