I'm not sure what the right answer is for steel-to-steel stuff. For a long time I sprayed everything like that with a marine preservative/rust inhibitor. Remember, I live in SaCal, in a coastal desert, where it just never seems to rain. No snow, no road salt, even mosquitos have been outlawed. So my opinion and experience are way skewed from those of others. My long-gone sea-doo trailer was galvanized, had bearing-buddies, painted hubs, galvanized wheels. I pulled the wheels after every ocean dunking and scrubbed all that stuff clean, dried before reassembly, then a coating of marine preservative to keep it all like new. That's not a practical approach for folks who drive in actual winter. When I lived in a winter environmnet, I had vehicles supposedly ready for it. Explorer with 4WD, and a Subaru wagon. No problems with either, although they too were desalinated very regularly.


Meanwhile.... the 928 question still goes to aluminum spacers and wheels contacting the cast steel rotor hats. Anti-seize on the cup faces of the nuts, threads clean and dry, torque to spec. No lube on the aluminum wheel or spacer face where it meets the rotor.

 

Now my head is spinning.

Had just been told and had lubed the lug nut threads and not the lug cup faces. Opposite of what I had been doing.
Now I've got anti-sneeze everywhere. As long as I can keep them monkeys and their monster air guns away from my lug nuts . . .

Sorry for the hijack. But to the technimacal discussion.

 

They OUTLAWED MOSQUITOS!

I NEED TO MOVE BACK! Whenever I walk out the front door of my house after it gets dark i always come back with damn mosquite bites around my ankles curiously? I hate the damn things!

 

Yeah-- Once I pumped out my neighbor's "fountain", the mosquitos went away. That was one of the miracles I discovered when I moved here from the "Great Swamp" area in northern New Jersey. Besides wearing shorts and a tank top in February, the insect profile changed a lot.

 

Garth is absolutely right. Properly torqued nuts with clean matting surfaces will absolutely NOT cause any kind of bolt shear. Granted that your existing bolts are in good order. Lastly, antiseize is necessary..it inhibits/displaces the moisture that will cause the oxidizing in the first place between the 2 contacted surfaces. These are standard practices at your local repair shop.

Goodluck
