What is the difference between driveshaft and axle?
The driveshaft runs down the center of a vehicle from the rear of the transmission to the rear differential gearbox and is visible beneath the vehicle. Axle shafts are concealed inside the steel rear-end housings running from the differential to each of the rear wheels.
Why the differential need the drive shaft?
In automobiles and other wheeled vehicles, the differential allows the outer drive wheel to rotate faster than the inner drive wheel during a turn. The average of the rotational speed of the two driving wheels equals the input rotational speed of the drive shaft.
Is the drive shaft the axle?
Usually, people refer to the longitudinal shaft — running front to back— as the “drive shaft,” and the transverse — from the differential to the wheel — as an “axle shaft.” Front-wheel-drive vehicles have two axle shafts, while four-wheel-drive vehicles may have two drive shafts and four axle shafts, for a total of six …
What does the rear end gear ratio mean?
Rear end gear affects your cars acceleration, top speed and gas mileage. What is gear ratios referring to? Rear end gear ratios or final drive ratio refers to the number of revolutions the drive shaft turns compared to one full revolution of rear wheels. A 2.90 gear ratio means the drive shaft turns 2.9 times in one full turn of the rear wheels.
When do rear differential gears need to be replaced?
Another common repair is to have to replace the gears in the rear differential. Over time, the teeth of the gears may wear down badly or chip. When this happens, you will deal with noise and a higher risk of failure, unless you replace them.
Is it good to have short or long gearing on rear end?
This short gear allows minimal power for quick acceleration but is not ideal for reaching top speeds. Now imagine riding down a long straight road cruising for top speed, you want to be in a higher gear to lower your leg rotations in relation to the rear wheel. This longer gearing is ideal for top speed but not for acceleration.
What kind of parts do I need to replace my drive shaft?

How do you change gears on a rearend?
The actual amount of change obtained will vary depending upon the gear ratio and gear size. A loose or high backlash (too much), is corrected by shimming the differential and moving it closer to the pinion gear. A low or tight backlash (not enough), is corrected by moving the differential away from the pinion.
How much does it cost to replace a rear differential?
Rear differential repairs that include a new gear set may be $1,500 or even higher between parts and the labor to replace them. These are among the more expensive auto parts out there. As you can see, a broken differential can be costly. If rear differential replacement is your only option, you can seek out a completed used assembly.
