How to check differential play

I just bought my first cougar not to long ago and I am going over the vehicle checking things out.

I was checking the half-shafts (which the CV joints are oK) when I noticed movement within the differential when I rotated the half-shaft back and forth. I checked my Hanes manual to see what the limit was on this play and it just says to check for excessive play.

What is excessive play? Mine rotates approximately 1/2".

The check is done by grabbing the half-shaft and rotating it forward and back. The play is where the shaft enters the differential. The tranny is in park with wheels on the ground.

thanks
Rob

Come on, somebody has a manual with the right specs.

Mine just says to check for excessive play.

This tells me that some play is OK, but how much is too much?
