Set your emergency brake. block the front tires so the car doesn't roll. Put the gear selector in nuetral. Jack both the back tires off the ground & then mark where your drive shaft is & rear tire. Then turn the tire exactly one revolution. You should see the drive shaft go exactly around as many times as what the gear ratio is. Example 3 full turns & 1/4 would be 3.23's. 4 turns & a tenth turn would be 4.10's. I hope I explained this well enough.
