Put the car in neutral, jack up one wheel. Mark both the wheel and the propshaft with some chalk. Rotate the propshaft 5 times. If the diff is a 5.625 then the wheel will go round 0.88 revolutions. 0.95 turns if it's a 5.25 and 1.02 times if it's a 4.9.
If you start with the wheel mark at 12 o'clock then the 5.625 goes round to half past 10, the 5.25 stops at half eleven and the 4.9 goes to half past 12.
