Lug torque?
 
Searched or this and got mixed answers. Is the lug torque 95 ft lbs or 110lbs??
It's a limited with the 20's if that matters. Just got done installing mud flaps and want to make sure rear wheel torque is correct.. Thanks!

Check the owners manual. It should be around 90-115 Ft Lbs

The Latest edition of the 2014 JGC Owners Manual says 130 ft/lbs of torque and the User Guide that came with the car says 110 ft/lbs and all other sources show the 14mm stem should have 85-95 ft/lbs. :wtf:

I did put 110 ft/lbs before I read the UG which showed 110. I averaged my two sources of information and came out to 110. Also I applied this torque during re-torquing. After driving for 150 miles or so the torque was different on each lug nut; I could tell this by the amount the wrench moved until it clicked. If the Torque wrench I used or my installer used was not accurate, it would also account for this. I am glad I re-torqued them as recommended. The installer said he put around 100 ft/lbs.

110 foot pounds on the 2014 Limited with 18" tires.

I just had my tires rotated and the lug nuts need to be re-tightened at 25 miles and 500 miles. From my understanding, it's because the wheels are so heavy that they "settle" when can result in loose lug nuts.

the last time I did this I found one lug nut per wheel that needed tightening at 25 miles and none at 500 miles.

It's a good thing that I have my own torque wrench because there is no way that I would go back to the tire store that often. (grin)

Where is this information located?

Regardless, you agree with me, the latest edition of the Owners Manual that was published on OCT 1, 2013 is wrong:

I didn't see that there was a 5th edition available. Perhaps they have changed the torque specification. They haven't updated the User Guide with a new edition yet, though. http://www.jeep.com/en/owners/manuals/

I found the torque in my manual booklet on page 146 step 10. It says that the torque should be 110 foot pounds. As for the tightening mileage (25 miles, 500 miles) it's from the notes section of the bill printout from the tire store.

Third Edition of the 2014 Grand Cherokee owners manual found on this board also has the same information on page 491 (page 148 on the user guide 3rd edition).

4. Finish tightening the lug nuts. Push down on the
wrench while at the end of the handle for increased
leverage. Tighten the lug nuts in a star pattern until
each nut has been tightened twice. The correct tightness
of each lug nut is 110 ft-lbs (150 Nm). If in doubt
about the correct tightness, have them checked with a
torque wrench by your authorized dealer or service
station.

5. After 25 miles (40 km) check the lug nut torque with a
torque wrench to ensure that all lug nuts are properly
seated against the wheel.

(Read the first line of my first post in this thread)

I am not sure what you mean, On October 9th, I downloaded the manual from the link you have shown above. I posted the page from the manual I downloaded from the link above. That is where I got the Owner's Manual. I clicked on the Owner's Manual Download Link on that page(illustrated below), for the 2014 Grand Cherokee. Someone here noted the new edition had been posted, that is when I downloaded it. Naturally, when I wanted to find the Torque to use with my torque wrench, I looked for the Torque page; I posted a copy of the page from that manual. Note: The Forth Edition shows a torque of 110 on page 534 the Fifth edition shows a Torque of 130 on page 538.

Here is that page again, it is page 538 of the Owners Manual downloadable from your link above:
