What gears are used in a differential?
In rear-wheel drive automobiles the central drive shaft (or prop shaft) engages the differential through a hypoid gear (ring and pinion). The ring gear is mounted on the carrier of the planetary chain that forms the differential. This hypoid gear is a bevel gear that changes the direction of the drive rotation.
How do I know what gear my differential has?
So an easy way to determine your actual gear ratio is to check the tag attached to the differential cover by the cover bolts. On the tag there should be some numbering such as 3.54 or 3.73, either of those numbers will give you the stock axle ratio.
How can you tell if you have 4.10 gears?
Jack up both sides at rear. Turn a wheel. If other wheel turns same way or doesn’t turn you have a posi. If other wheel turns opposite way you have open rear.
What is the gear ratio differential?
Differential Gear Ratio determines the number of times the drive shaft (or pinion) will rotate for each turn of the wheels (or ring gear). So if you have a 3.73:1 gear ratio the drive shaft turns 3.73 times for every turn of the wheel. If you want to increase off road performance you might want a 4.10 or lower ratio.
Which rear axle is mostly used?
Generally, two types of rear axles are applied in rear wheel driven vehicles: the single reduction and the hub reduction rear axle. The single reduction rear axle consists of a spiral bevel or a hypoid gear.
Which gear is called the heart of the differential?
The pinion gear is attached to the end of the drive shaft as it enters the differential case. It rotates as the ring gear rotates. Sideways through the center of the differential case is a shaft on which two planet pinion (or spider) gears are mounted. These small gears are the at the heart of the differential action.
What gear ratio is a Dana 35?
The Dana 35 is used extensively in the Jeep models. This axle had a GAWR up to 2700 lbs….Available Gear Ratios.
| Ratio:1 | Pinion:Ring Teeth |
|---|---|
| 3.08 | 13:40 |
| 3.31 | 13:43 |
| 3.54 | 13:46 |
| 3.58 | 12:43 |
What is a good gear ratio for a street car?
If we have a daily driver, 2.55 to 3.25 gear ratios typically work best, whereas a street/strip application we would usually use a 3.42 to a 3.90 gear ratio, and race applications most commonly use a 4.10 and above gear ratios.
