Lug nut torque

[Marquitos]

Can someone tell me the correct foot-pounds of torque needed for the lug nuts on a 2002 3500 dually with the OEM stock steel wheels? They don't seem to give that information in the owner's manuals. Thanks.

Thanks SoMnDMAX.

Did you get that info from the user or service manual?

------------------

[gmsi]

the service manual says 175 lb ft for dual wheels and 140 lb ft for all single wheels.

Owners manual says 140 for 2500HD, does not specify for steel vs aluminum wheels though.

Back to the top....

During my rotate & balance today I found the following:


Dealer 1 - don't go over 100 ft lbs
Dealer 2 - 120 ft lbs 'I think' he says
Dealer 3 - 140 ft lbs

The owners and shop manuals state 140 for singles (doesn't specify steel or PY0 - Aluminum)

The Sears store last time I went said 90 ft lbs, today it's 140 ft lbs.

What B.S. this is !!! All I want is to maintain the truck properly and even dealers can't agree.

Anybody else use a different number?

I plan on going with 120 ft lbs and waiting to see what others are doing.

Just got new Centerline wheels a couple weeks ago(Comet III's, 16 X 8). The tire shop (reputable) torqued them to 100, as he said they do for all 8 lug singles. I thought it should be more, so I read the paperwork that came with the new wheels. It recommends 85 to 95 (??). I left them at 100, confident I had sufficient overkill. Now I'm not so sure.

175 on the duals sounds right. I've done that for years, but only on steel wheels. Don't know what aluminum would be.

MDrag......LMAO..
You have to get a hold of yourself...You are starting to cite information like an attorney.....

Section 3-94 of the 2001 Helms...........

Sounds like this, In accordance with Statute implied in Jones Vs Smith, the plaintiff was deemed clear to proceed with cross as per section 11-32 of State Penal code, wherein such as, in leiu of.....Your Witness counseler....HAHAHAHAHAHAHA.
OBJECTION...OVERRULED!

On a closing note...

Thanks for the information....it is the same for Dually's...Ooops Dooley's...as it has been since 93-94 I believe. Even with Alcoa's the Torque requirement is the same. Hopefully none of you experience a road side repair and try and take off the lug nuts with a 3/8 drive and 9" extension....;D

Torque em tighter, maybe you'll go FASTER !?!?!

While your at it, dont you think you should change the air in the tires??? It must be getting pretty old by now???

But seriously now, this is a serious matter, that very few dealerships or tire shops adhere to. I've never seen a torque wrench at any tire shop!

NorCalDMAX,

...You are starting to cite information like an attorney...

That's REALLY depressing me....

Lawnboy,

...I've never seen a torque wrench at any tire shop!

I'd switch shops if they do not use torque wrenches. Improperly torqued lug nuts are a potentially HUGE problem. They even have them thar tork renches in OK.

MDrag,
You know I got to thinkin bout that lawyer crack and want to retract it.

I forgot just how Shallow, sleezy, cheap those people are. Especially the "Contingency" attorney's...they are the worst..they are why our auto insurance is so high...

Please accept my apology....

I am instructing the JURY to disregard the comment setforth by NorCalDMAX in regards to MDrag and the attorney statement...HAHAHAHAHA. That is speculative and leading.....

The reason you don't see different torques for the PYO Aluminum wheels, as you usually will for alloy wheels, is that the PYO's have steel inserts at the holes, for the lug nuts to torque down on.

NorCalDMAX,

I feel better now. But you do have a point, a too dry and technical post, not even a smiley - I'll try and do better. I HOPE THE TEACHER DID NOT SEE THAT ONE...

MDRAG.
Could you put DUAL lug nuts on each rim. (16 lugs) Just thinking if 8 is good then 16 would be better!

[BigBob]

In Ontario, were we have all the Laws to protect us from ourselves, to install or mount a truck tire you must complete a provincial coarse first. They state that over torque is worse than under torque, because in a over torque situation lugs become brittle and can snap off under stress. All installations must be torqued. Then after installation you must return after a 100 km to have them retorqued. When I had tires put on my car, at Wal-Mart, the mechanic torqued them then the counter person went in to the garage and rechecked all his torques again, and I had too sign, that I would return to have them retorqued after 100 km. My dealer clearly stated that 140 lb was the number for my truck.

In addition to the recent string:
http://forum.62-65-dieselpage.com/ub...c&f=7&t=002953
I wanted to bring this issue up again. Some of the
contributors have been insistant that the torque
be at 175 ft lbs, however I just had my 2002 dually
tires rotated at 7500 miles at the dealer. I made
him check with GM and they say that the "new style"
lug nuts should be torqued to 140 ft lbs....no more.

I don't know when the "new style" lug nuts
came into production, but since my truck is 3
months old.... I'm going with their current
recommendation of 140 ft lbs.

Does anyone have the Helms manual for the 2002
models?

[mwillis]

My manual for the 2002 Chev. 3500 dualy clearly states 140 ft.#
