You would be fine with .004.

As important or even more important is the TIR of the output shaft after bolting onto the brake drum. You can have proper clearance on bushings, but if those bushings are not dead nuts, you will have more runout than the 4th main can handle.

Total Indicated Runout

The maximum excursion from a "0" point

I believe that information is in the service book.
