do not tighten to 80# too tight, use the proper lug wrench or breaker bar and tighten until they are all very snug. There are very few fasteners on the old Fords with any torque value.

THANK YOU 40 COUPE. DON'T KNOW WHY I THOUGHT 80#. I'M A "TORQUE SPEC" GUY IN ALL MY WORK SO IT JUST CARRIED OVER TO MY OLD FORD CARS AS WELL. IF I DID TORQUE TO 80# ASSUME I'D DEFORM THE BREAK DRUMS? I USE A SNAP ON BREAKER BAR AND 5 INCH EXTENSION AND 3/4" SOCKET, NEVER AN IMPACT WRENCH.

I disagree with 40 Coupe. 80 ft lbs will not be too tight on clean dry threads. I tighten mine in 3 stages to ensure even seating of the wheel.

DEUCEMAN aren't the lug nuts supposed to be 13/16. If you are using 3/4 nuts, the shoulders of the nuts might be to small, You might want to check this out, my 3 cents worth,37RAGTOPMAN

75-80 ft lbs is about right. The secret to not deforming drums or discs is to tighten the lug nuts in a sequence that calls for opposite nuts to be tightened as you go. On old hubs, a touch of anti-seize compound won't hurt, or change the tension, but makes it easier if you have a flat out on the road. In our shop, we do spin on the lugs with an air wrench, but if they are too tight when torquing, we back them off, then retighten to specs. Some service stations just turn on the wrench. We have found them so tight that it took a piece of pipe on a breaker bar to shake them loose.

P.S. If your lug nuts are not 13/16, you may have the wrong ones, which will not seat properly in the wheels. All standard Ford lug nuts, '32-'70, use a 13/16 wrench.

Thank everyone who replied. I will check out all suggestions from wrong size lug nuts to tightining in proper sequence to a dab of anti-seize, they all make sence and I know will help. Your all good guys..

Anti-seize? Wow! And to think that all these years I thought that was what the oil dipstick was for. Learn something every day, I guess.
