Bill -
This back and forth play will always be identical on both sides because of
the spider gear assembly in the differential will put the play to one side
or the other or both, depending on whether one wheel is being held in place
or not.
1/2" of play isn't anything to be worried about. Just make sure your diff
is full of oil.
You probably should check your U joints while it's jacked up. Put the car
in gear (give some resistance from the motor) then have a person hold one
wheel and spin the other one back and forth. If you see movement between
the driveshaft and the diff or gearbox, then you know you U joints are bad -
pretty easy repair job while the car is up.
