Re: Gear ratio identification
Jack up the rear of the truck with the truck in Neutral. Mark the drive shaft and turn one tire one complete rotation and count the number of times the driveshaft turns. If it turns 2 3/4 times, you have a 2.73. If it turns a tad over 3 times, a 3.08, not quite 3 1/2, a 3.42 etc.
