Torque figure for lugnuts

I think I'm about to take on rotor/pad replacement on my 2006 Commander...I've read through the threads on brake replacement here and thank all those who've helped others by posting the how-to information.

One torque figure I can't find is the recommended torque for the lugnuts when re-installing the wheels when the job's done...can anyone point me in the right direction?

tnx.

Craig

Craig,

I think it is in the manual somewhere but I know it is 100 ft.lb.....tighten to 80 ft.lb. and finish at 100...no lube on threads.

Rob

I use 95 ft lbs. That is what the dealer recommended but 100 works fine too.

I have Spidertrax wheel spacers on my XK. Spidertrax recommends to torque wheels to 90 ft lbs. I've had them installed for over two years now with many hardcore off road trips and never had a problem with any lug nuts coming loose.

I have NOT seen a specific figure for the Commander, although I haven't looked very hard, but every figure I have seens for all the Chrysler vehicles I have owned has been to the effect of 95 ft-lbs +/- 5 ft-lbs. I have set my torque wrench to 95ft-lbs and toqued down my Chrysler wheels slowly (moving the torque wrench quickly can throw off the actual torque it clicks) in a criss-cross pattern, for 5 lugs, that makes a star pattern. I've never had a problem, BUT, the Commander is my first vehicle with bigger than 15" wheels.

I also install the lug nuts dry, and only seen official recommendations to do it that way. The lube can through off the results of the torque wrench and you can over torque the fasteners. I had a '91 Mini-Van that I always liberally lubed the lug nuts before torqueing them down, all the lug nuts and studs went bad, deformed threads. I replaced all of them on the Mini-Van, but kept doing the lube thing and after several tire rotations, the new lug nuts/studs were bad again. I switched to keeping them dry, after replacing them all again, and never had a problem again.

You'll find folks that will tell you, they use lube or anti-seize on the studs/lug nuts all the time, and never have a problem. I don't doubt them, it may vary from vehicle to vehicle, but the recommendation is torque the lug nuts dry.

Something like wheels, its often the torque that is best for the fastener that is specified, i.e. you toque down the wheel as tight as the fastener can safely handle the torque. I could be wrong on that, but if you look up the recommended torque for a stud the size that is on your commander, likely it is the same as the recommended torque for the wheels.

Of course, like everything, we don't know more than the designer and/or manufacturer, look up their recommendations and follow them, they trump any other advice you would get.

What does the spacer manufacturer recommend? Sorry, NOT the answer you were looking for, but if someone that doesn't respond, I think you need to e-mail or go to the manufacturer's website and see what they recommend.

Did you have to install longer studs to use the spacer? Or is this one of the spacers that bolts to the hub and then the wheel bolts to the spacer?

SpiderTrax recommends 100 ft/lb. As Robbie said, this would be for the wheels as well. When I initially put the spacers on, it was all I could do to remove some of my lugnuts, even using a 3/4" breaker bar/deepwell socket! Dreaded air guns! They were probably a "little" higher than 100 ft/lb.

Yea, air impact wrenches really do a number on the lug nuts, they are so inconsistent with torque you can expect a shop that uses them will over torque the lug nuts greatly. The only way to install wheels is to use a torque wrench, at the very least, if you do NOT have a torque wrench, the vehicles lug wrench seems to be designed to apply close to the proper torque if an average strength male uses it to tighten the lugs as hard as he can without straining greatly.

Thats funny because I still have my installation instructions for my 1.25 inch Spidertrax wheels spacers and they say right on there torque to 90 foot pounds.
