Hi eveyrone,
Purchased a new front drive shaft (type that still uses the flange at the front diff, but uses a new yolk at the t-case).
Does anyone know what the torque setting is for the 4 bolts at flange?
Also, what is the torque setting for the four bolts that secure the shaft to the yolk at the t-case?

Year is 2012 JK - not sure if that matters.

thanks!

Yes blue lock tight and after the lock washer is flat go just under a half a turn. You don't want to over tighten those on the u joint.

Local Jeep dealership says 89 ft lbs for the 4 bolts at the front diff flange. Going with that number. Locktite enabled. Ready to go. Thx everyone.

By the way, how do you get a torque wrench on the t-case 4 yolk bolts? No room in there. I just hand wrench tighten and guess 17 ft lbs. hope it's good! Is there a mini torque wrench?

Bump. Need to know and nothing definitive here. 17 ft lbs sounds more like the original 8 bolts. Now that it's just 4 bolts, 89 ft lbs sounds more accurate. Can someone confirm?

No way it's 89. I'd guess closer to 20 is more accurate. Honestly with driveshaft bolts, I just do a drop of locktite and tighten them down good. Check them after 100 miles to be safe.

Edit: I retract that. I just went and looked at ours. I remember them being much smaller. Looks like they're a 12mm, so they could be that high. Again though, I've always put a drop of locktite and tightened them.

That link above says 81.

Yeah, looked at Adams driveshaft instructions and they say there's no specified torque so use plenty of red Loktite.

I put a bunch on there and am tightening down to 80ft lbs. Same amount as I'll do on the front bolts.

Thanks Doug.

EDIT: screw it, I can't get a torque wrench on them anyway. Just gonna crank them down without going to hard on them.
