  1. Page 349 of the Owners Manual 3rd printing recommends 100 ft lb torque.  As for lubing the lug nuts, opinions vary, but from a Corvette forum:

     

     

     

    Discussion: I've worked on several bolt torquing issues & systems for GM over the years. Any applied torque is meant to establish a 'desired' tension value in the stud/bolt; this translates to an amount of stretch in the bolt. That applied stress needs to be below the permanent deformation strength of the stud/bolt, or it will permanently stretch and lose torque and retention. Too much, and the stud/bolt snaps. So, if you lube the threads or the joint, the same applied bolt torque will result in higher strain/stretch in the stud/bolt. If it doesn't exceed plastic deformation levels...no harm done. If it does, but doesn't exceed permanent deformation levels, the stud doesn't snap, but it does lose strength and bolt retention. The stud/bolt can snap, if the torque level is high enough and quick enough.

    Bottom line: A little anti-sieze on the stud threads will probably not snap the stud if the correct torque is applied in the normal manner. If an overpowered air gun is used, the stud will likely snap before the nut/driver ever slows down.

     

     

     

  2. "The only negative I see about getting the Windstar tire is that it may be dirty and need some sanding and paint for the spare is outside the car.  Mine while 13 years old does not look dry rotted to me."

         Obob, I was appalled at the condition of the original tire on my Freestar when I removed it at 9 years and 50,000 miles.  Still don't know why it hadn't disintegrated on the road.  From the following:

    The current industry association recommendations regarding inspecting and replacing tires due to age originate outside the United States.

    The British Rubber Manufacturers Association (BRMA) recommended practice issued June, 2001, states "BRMA members strongly recommend that unused tyres should not be put into service if they are over six years old and that all tyres should be replaced ten years from the date of their manufacture."

    "Environmental conditions like exposure to sunlight and coastal climates, as well as poor storage and infrequent use, accelerate the aging process. In ideal conditions, a tyre may have a life expectancy that exceeds ten years from its date of manufacture. However, such conditions are rare. Aging may not exhibit any external indications and, since there is no non-destructive test to assess the serviceability of a tyre, even an inspection carried out by a tyre expert may not reveal the extent of any deterioration."
