when measuring drive axle flange runout, it is necessary to:
○ a. remove the cv boot.
○ b. remove the center support bearing.
○ c. remove the wheels and brake rotors or drums.

Explanation:

To measure drive - axle flange runout, the wheels and brake rotors or drums need to be removed to access and measure the flange accurately. Removing the CV boot, center support bearing, or the drive - axle flange itself is not necessary for just measuring the runout.

Answer:

C. Remove the wheels and brake rotors or drums.
