Front axle nut (halfshaft nut) Torque?

Just to not get confused.

Torque specs Front axle nut (half shaft nut).

I looked at post on this forum, and some people writing different torques.

Im looking for the torque specs of the Front axle nut (half shaft nut), not to confuse with the 5 lug nuts to put your wheel on.

I see posts coming by, with torques of 100 Ft. Lbs for this bolt. While mine manual tells me 185 Ft. Lbs for the big bolt (half shaft nut). And the

Wheel Lug Nuts 100 (+/-15) Ft. Lbs.

So tell me if im correct at 185 Ft. Lbs for the big bolt (half shaft nut)?

My paperback 2007 FSM and my digital copy of the 2005 FSM both list 100 ft-lb for the axle nut in Section 3 - specifications - half shaft.

Where exactly are you seeing 185?

I'm at my work right now, but I will tell you later in what section and on what page it is! I don't have the manual with me 😃. But honestly a nut of 36 mm on a torque of 100 ft-Lbs must be a joke! For small lug nuts I can see it! But for a treath and bold that big, it's just not possible. All the cars I tourqed on, are at least between 165 and 195 ft-lbs for a axle nut.

Its certainly possible. All depends on how much clamp force is required by design.

Let me know what your manual says when you get home.

http://dl.dropbox.com/u/58723210/13-2.pdf

Halfshaft nuts 185 Ft. Lbs. 251 N.m

Matt :Maybe you have a outdated manual or a fob?? I didn't knew they had jeep commanders in 2005 as you say in your digital manual from 2005???


But anyway, I put a updated copy of the Torque page from my service manual 2006-2010 for you.

My digital copy is the 2005 WK- same as the XK.

But my 2007 is a hard copy. What does the torque value say in Section 3 in your manual? I'll check my hard copy

Definitely a discrepancy in the FSM. Good find!

I'll be sending an inquiry to Jeep. While I agree the 185 seems right, 100 isn't unheard of. There's a few GM SUV's that use that value and the KK's use 100 ft-lb as well.

I just torqued mine Sunday after replacing my LCA so I'm looking forward to Jeeps response.

Like I say The torque value in section 3 (says 185 Ft. lbs).
it is really impossible 100 Ft. lbs.

On a 36 socket for that nut, they put a 3/4 hole, you really think they did that to make 100 Ft. lbs of torque?? Why do you think people use extended pipes to torque that bolt?
