The size of the front ring gear in a 1992 Chevy pickup is 7.5 inches. The 7.5-inch ring gear needs a 26 spline axle shaft.
These cars came with a 10 bolt, 8.5" ring gear and an optional 12 bolt 8.875" ring gear.
8.5"
8.6
Count the # of teeth on the ring gear. Now count the # of teeth on the pinion gear. Now divide the small # into the big # and that will be your gear ratio.
Ring gear size is 8.5 inch , 28 spline axles .
8.2"
The # of teeth on the ring gear and the pinion gear. There is always more teeth on the ring gear then the pinion gear. And the way you determine the gear ratio is devide the # of teeth that's on the pinion gear into the # of teeth that's on the ring gear and that will be the gear ratio. The 4 gears that are the same size and run together is called the spider gears. Do not count those gears they have nothing to do with the gear RATIO.
To determine your diff ratio, remove the cover, count the teeth on the ring gear, then count the teeth on the pinion gear. Divide the ring gear number by the pinion number.
9.25 inch axle
You could remove the diff cover and count the number of teeth on both the ring and pinion gears, then divide the number of teeth in the pinion into the number of teeth on the ring gear and you will have the ratio.
what size truck? 1500,2500,3500?
