Checked with supplier today - Southwest Wheel. Lug nut pictured above will work for the 94-02 duallys but you go to a larger hex size. 15/16" to a 1 1/16", which might be better and it saved me alot of greenbacks.

HID, that must been some ride

 

Are you guys sure about the 350ft/lbs torque spec? My 2003 3500 has a wheel torque spec of 145ft/lbs. I find it hard to beleive that these bolts are capable of 350ft/lbs!

 

*junkie. In the picture above of the nut it is marked right on the nut 130 ft lb.

Haynes Manual for '94 - '01 trucks says, "8 stud dual wheel 145 Ft lb.
8 stud single wheel 135 Ft lb."

Many tire shops use big, 3/4" or one inch, impact wrenches and have $5.00/hr kids using them and they make the nuts/studs too tight. This will "stretch" both the studs and the nuts and many times that will cause them to come loose after a period of time.

When I'm at the tire shop I specify I want them to just get the nuts snug with the impact wrench then use a torque wrench - without an extension - to finish them off. Then I watch to see that it is done that way.

Also, they often lay the wheel on the ground so the center hub of the wheel touches the ground. When they pick it up it will have dirt and sand on that center hub and, especially on duals, when the wheels are torqued the sand will keep the wheels from getting tight. Over time the sand will work it's way out and the wheel will be loose. I always make sure they use a clean rag and wipe the center clean before putting them back on the truck.

 

My owners manual list the torque values for the dual wheels at 300-350 ft. lbs. I tried to scan and upload, but it won't take an adobe file, so the jpeg is the best I got

 

Lugs are not really that big a deal. I have never in my life had a wheel come loose. That is on a big truck or small truck, either Dayton or Budd. Part of the key is to lube the studs first. WD40 works well as it washes off easily. One shop that I worked in used spray wax, like pledge. You cannot get proper clamping with a dry thread. Just spray them, tighten them properly and tight. I have no idea what torque that I put then on, probably 150 or 175 and of course tighter on the big Budd wheels. It is also good to run a large file over the surfaces to take off any burrs. This goes for brake drums or any spacers that may be under the studs.

Every once in a while look at the stud/nut area. If one is loose there will be a rust line radiating out from the nut on the wheel. This will happen on either acorn or flat nuts with the washer unless you manage to drive the thing and never get it wet. A strong 3/4 impact will take just about any nut off and tighten it well. Many years ago I sold my one inch because I did not need it.

Proper maintenance includes looking things over now and then. There are a lot of signs before any wheel will come off. If one gets loose there will also be dramatic running vibrations to let you know there is a problem. Hey guys, just lube them, use the tightening pattern necessary to snug them up tight, then go over them again with the same pattern and make them good and tight. You will never have a problem. If I put a torque wrench on a wheel I would be afraid that someone might see me do that, terrible embarrisment :- I doubt that many have a torque wrench heavy enough to be meaningful. Only someone doing diesel work would. Mine was purchased to torque 325 ft pd Detroit heads.

 

Well I'm a member of Torque Wrench Anonymous.

"Hi, my names Chris, and I have a torque wrench problem. My neighbors have seen me use it on my lug nuts".

When I was 16 I lubed some lugs on a '68 Ford LTD thinking that'd make them come off easier next time. Guess what, I was right. One wheel almost came off without me even trying.

 

For all of those without a hunker of a torque wrench, just get some of the red locktite and put a good bead on the stud, tighten the nut with what ever you have and forget about it,,,UNTIL time to take em off

Got the wheel lugs today, it says 140 ftlbs on them.
