Is rear axle and differential the same?
A differential is part of the front and/or rear axle assembly. The axle is the central shaft that the wheels on the vehicle rotate around. The differential allows this to happen. Two wheel drive vehicles have one axle and four wheel drive vehicles have two.
What is an axle pinion?
Pinion Gear – The pinion gear is the drive gear that turns the ring gear. Find: Ring and Pinion. Pinion Angle – Pinion angle refers to the angle that the axle yoke is at compared to the drive shaft and the transfer case or transmission.
Is Dana 44 high-pinion?
Dana 44 front axles have either standard or reverse-cut gears. In the off-road vernacular, we refer to them simply as low- or high-pinion, respectively. Designed initially for rear-drive applications, the standard-rotation (or low-pinion) axles run backwards when used in a front axle application.
What is a high-pinion rear end?
A low-pinion axle positions the pinion below the centerline of the axle, while a high-pinion axle places the pinion above the centerline of the axle. By design the coast side of the gear is weaker, so a low-pinion front axle is going to be weaker than its high-pinion equivalent.
What makes the pinion spin on an axle?
As the pinion spins, it turns the ring gear which powers the axles. The pinion bearing and race allow the pinion gear to spin smoothly. Low fluid levels can damage the ring and pinion gears inside the axle as well as the bearing and race.
Why are pinion bearings used in drive differentials?
In drive differentials found in cars, pinion bearings help the smallest gears in the differential work smoothly. Differentials are made up of a series of gears and cogs, and it is the smallest gears that allow one wheel to safely rotate faster than the other.
Why do pinion gears make a whirring noise?
The pinion bearing and race allow the pinion gear to spin smoothly. Low fluid levels can damage the ring and pinion gears inside the axle as well as the bearing and race. Damage to the pinion bearing can cause the pinion to emit a whirring noise when accelerating or slowing down.
Why are pinions only move in one direction?
Pinion bearings ensure that pinions only move in one direction, thus making the overall machine more efficient as no energy is lost on undesired movement. They also are designed to reduce friction in the direction of desirable movement, again increasing efficiency.

What is the difference between pinion angle and pinion pre load?
Pinion Angle – Pinion angle refers to the angle that the axle yoke is at compared to the drive shaft and the transfer case or transmission. Pinion Pre Load – Pinion Pre Load is the amount of drag that is required to turn the pinion shaft. Drag is a load or resistance keeping something from turning freely
What’s the difference between ring gear and carrier bearing?
This unit transfers the motion from the ring gear to the axle shafts. Carrier Bearing – These are the bearings that ring gear carriers ride on. May also refer to the driveshaft support bearing used in multiple-piece driveshafts. Chromoly – Chromoly is an abbreviation for “chromium-molybdenum steel.” Sometimes called Chro mo.
