What type of lubrication for wheel lugs?

[Warviking]

I'm going to be getting new tires and will need to take the wheels off. From other posts I have picked up that it's good to put anti seize or lubrication on the bolts and part of lug that goes against the wheel? What type and brand do you use? I'd like to find something I can run out a pick up. Don't want to use wrong lubrication and have wheels fly off either. thanks.

Anti-seize is anti-seize. Just get the Permetex or whatever. Put a little on the lug nut where it seats in it's bowl in the wheel. A light oil on the studs is all that's necessary. I like to clean those studs with a tooth brush and your favorite cleaner. Same with the threads in the huts. I hate it when they feel gritty when you are spinning them on by hand.

A dab the size of a small booger is enough!!!

Actually, there are differences. Some anti-sieze is for high temps. But, here Porsche says to use one type of Optimolly (HT, I think). It does NOT change the torque values as others usually do. [Of course, lots of us bumpkins have used whatever for decades before finding that out. I sure did. But why not be anal and do what they say - otherwise you wouldn't be a true Porsche owner.] So do a search on optimolly or however it's spelled and you'll find the thread that ID's it for sure. Oil will change torque/tension relations vs. dry threads by maybe 20% or more.

Agree re the grit.

After cleaning that out, put a small amount of the anti-sieze on the curved part of the mating face of the lug nut, and on the threads. Or if the TSB says none on the threads do that.

Bruce Anderson published the TSB in his Excellence column some time ago.

Ahhhh....ummm...any lubricant applied to a threaded fastener will alter the torque value relationship ( vs dry torque values). I can't imagine Optimolly HT being *both* a lube *and* having characteristics similar to dry value torque....

Doesn't compute ......

Optimoly HT. Molibdenum is slippery stuff. I just checked and my tube has a Porsche part sticker on it with part # 000 043 020 00
The tube says Optimoly TA (not HT) but the description on the back says its for high temperatures. It's made by Castrol, probably not in the US.

Correction: Optimoly TA is not the same as Optimoly HT
Optimoly HT is part # 000 043 004 00

Isn't Molibdenum based grease used for engine assembly in high stress/high temp areas (cams, valve trains, crank etc.)? Sounds like overkill for wheel studs/lugs/bolts.

FWIW, I just use the plain ole silver colored anti seize stuff (Pematex?)on mine and I've never had a problem.

I just use it for the critical fasteners where Porsche specifies it. I use good old copper antiseize for lug nuts.

You guys can make a mountain out of a molehill.

Now we're gonna have a thread 10 pages long about friggin lug nuts and the many different ways to bolt up the space shuttle. You'd think he asked about rod bolts if you didn't read the question.

I hope poor ol' Warviking understands the nature of this BBS and all of it's over-educated engineers. Clean 'em up and put a booger's worth of anti-seize on the mating surface of the nut, torque up and drive!

I was warned against using anti-seize on the aluminum lug nuts, so I use a medium weight oil instead. If I change to steel lug nuts, I'll go back to anti-seize.

Anti Seize is fine...my point was simply that lubed torque values are usu less by 20-40% than comparable dry values.

Never let someone else lube your nuts, I only trust myself.

[911pcars]

What kind of antiseize do you guys recommend? :-o

(I only want to extend this thread by another 4 pages)

Not only on my P-car but even since I was younger I simply use a drop or two of any motor oil I have around, it works fine...

this doesnt sound very engineering like
a booger can up to 0.4327 milligrams. be more specifie!

[Steve 82SC]

In talking with Al Reed after he refinished my Fuchs, he was quite adament that the lug nuts be put on and torqued absolutely dry. I asked him about thinly coating the rounded shoulder of the lug nut with anit-seize, but he insisted upon dry.

I used antiseize at first but then quit after having it burn-up and smoke from the friction everytime I removed one of the lug nuts.

[sundaypunch]

I make sure everything is clean and put them on dry. I've never had a problem. I think this is one of those areas where any reasonable approach will work as long as you hit the 94 ft-lb spec.
