Title: Wheel stud torque
Post by: Timkar on May 07, 2011, 02:37:04 PM
Thought I'd check to see...
Just wondering what torques and methods people are using? i just ended replacing all 10 studs on my DS steer as only two nuts were holding properly. The others had all been stripped. I torqued to 550 ft lbs dry

From Sec 15 , page 15-1 of the manual:
"Wheel studs are RH thread on the right side of the coach and LH thread on the left side. Wheel studs should be torqued to 550 ft lbs on steel wheels , 350 ft lbs on aluminum"
And then about 10 lines further down...
"Studs and nuts should be lubricated with Texaco Molytex # 2 or equivalent"

TIA....Tim

Tim, I have always used never seize on the studs and nuts torqued to 350 for the aluminum wheels 500 for the inner steel wheel never lost a wheel, stud or nut yet some of these guys here will hammer on you about the lube on the studs ,nuts and the torque worked for me,I even use a little on the nut surface keeps the nut from peeling the aluminum on the wheel

good luck

  Wierd. When I was young everyone used to put a lil dab of grease on the studs. Not a lot, and not oil. Then the late 70s came along and everyone started saying dry dry dry. And thats about the time you started running into wheel nuts you coulnt break loose without serious heavy duty equipment.

  I could really see the need when tightening the nuts down against aluminum, the steel nut could actually tear the aluminum without some kind of lube.

Clifford,

I have always maintained the use of never-sieze, but have resisted. I will now apply & use on the AL wheel where the nut seats.

I have used N-S in many vibration applications and never have backed out..
I did lose a wheel, at age 6, My mother was driving back from church, a noise, vibration, and then the RR wheel/tire from our 1954 Buick Century Special passed us !!

I have learned that no seize is your friend...especially if you ever want to get the part off again.  I use it all the time.  I have to say though, I never thought about using it on lug nuts where the nut and aluminum rim meet.  Great idea.

I grew up in Illinois where salt is plentiful.  I use anti seize on EVERYTHING. If you didn't parts just seemed to weld them selves together.

From the 1999 Alcoa wheel manual, pg 23. Now I'm really confused??

"It is recommended that stud threads on stud located mounting systems be lubricated with SAE 30W oil and torqued between 350 and 400 foot-pounds. If threads are not lubricated, torque to between 450 and 500 foot-pounds.

Note: when dualing steel wheels with Alcoa aluminum wheels, follow the steel wheel manufacturer's recommendations regarding the proper torque and use of thread lubricants to mount the wheel.

WARNING  Application  of  lubricant  to  the  ball  seats  can  cause  excessive
torque. Over torque can stretch studs causing them to fail.

Overtorquing can lead to wheel disengagement causing injury or death.

Do not allow oil to contact ball seats or mounting surfaces of the wheel, hub
or drum. Do not use aerosol cans for lubrication of stud threads."

Did I mention I hate Al wheels??

That's Alcoa take on it using oil 12 years ago keep on digging I never ran Alcoa aluminum wheels or used oil,they love for you to peel the aluminum from the socket

babell2,

Smart move. I wish my steel wheels/tires from my 4104 fit my 4107.

My offer still stands to trade the Alcoas for a good set of four steel wheels straight across if the tires are equal or by switching tires. In other words, at no expense to me.

Watching Nascar would you believe they used never seize on the wheels sockets and Teflon coated lug nuts 200  mph should work on a bus you think lol

good luck

But remember those studs never see another race and the lugs only make it one change.
