Replacing FJ40 Knuckle Studs - Torque? LocTite?

[CharlestonG8R]

I'm in the middle of replacing the bearings and seals on my knuckles. And a few other things... While in the area I thought it would be wise to go ahead and replace the knuckle studs. Okay... The FSM states to torque the nuts to 79 ftlbs but gives no value for torquing replacement studs. Using the nut-on-nut method, I broke the first of 16 studs trying to get to that torque value. Upon further review, I'm not sure there actually is a value out there. I'm sure someone has replaced these things before, what torque did you use? I have the larger studs that are stock in 1981. Thanks!

I have the larger studs...

Bragging?

There is no torque listed in FSM other than generic tables based off fastener size and strength. Consensus in 80tech seems to be install and snug them up “tight”. It’s the clamping force from the nut/cone combo that holds things tight.

CDAN did list the torque for an m12/14? I believe buried in a thread somewhere.

I’ve just snugged them down like Jason mentioned and was sure to regularly check them...there is usually one that is loose.

Edit - I did use red loctite when installing my arp studs.

"snug" is way too subjective for something as critical as knuckle studs. What length wrench/ratchet/breaker bar are you using? How big are your arms? Get my point?

I used to do ~70-80ft/lbs on the nuts on my FJ60 axles. Studs get torqued ~25ft/lbs into the knuckles. Loctite everywhere, red high-strength s***.

Thanks for the responses. I torqued all of the studs to 28 ftlbs and used red LocTite on all of them. And I follow what your saying... One man's barely snug is another man's way too snug...

On another note, it looks like Fred Anderson may have sold me the wrong rotors. They're close, but they're missing 2 holes... Evidently this is a common problem with the later 40's.

Does anyone have the correct part numbers for the inner and outer hub bearings? Also, does anyone have any tricks for removing the inner hub seal?

Buy the trial gear set. It comes with everything you need to rebuild the hubs.

Well, I have everything, I just wanted to verify the part numbers on the bearings... Fred Anderson sold me (2 ea) 90080-36067 and (2 ea) 90368-49084-77... I've been trying to find these part numbers on Mud and haven't been lucky yet. Since I'm going to try to get them to take the rotors back I wanted to verify that the bearings are right first.

i can’t help you with the PNs, but next time, stop in at Hendrick Toyota. Ask for Dan, and let him / them know you’re part of the LCLC club....
