What are the parts in a rear differential?

What are the parts in a rear differential?

Pinion Drive Gear: Transfers power from the driveshaft to the ring gear. Ring Gear: Transfers power to the Differential case assembly. Side/Spider Gears: Help both wheels to turn independently when turning. Differential Case Assembly: Holds the ring gear and other components that drive the rear axle.

What are the components of a differential?

Components Of Differential

  • Drive pinion or Bevel pinion.
  • Ring gear or Crown wheel.
  • Differential case.
  • Differential side gear or Sun gears.
  • Differential pinions or Planet gears.
  • Axle shafts or Half shafts.
  • Pinion shaft or Cross pin or spider.

How much is a rear differential part?

You can expect a rear differential replacement to cost up to $4,000. Now that you know what to expect for a rear differential repair you have the information to decide whether or not a replacement is worth the cost and if a new car might make the most sense for you.

What is a rear axle differential?

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 photo below shows where it’s located on a vehicle with a four wheel drive automatic transmission. The differential allows wheels on the same axle to rotate at different speeds.

What is the rear axle assembly?

A rear axle assembly is a very large and heavy piece of steel and iron that is used to propel the vehicle by converting rotational force into linear motion. The drive shaft sends rotational power from the engine and transmission to the rear axle assembly differential.

What kind of axle do I have?

Stamped Number on the Axle To figure out exactly what axle you have, you can look for the Dana stamped bill of materials number. This stamped number can usually be found on the righthand side or on the longer axletube on the same side of the tube as the differential cover, facing the rear of the truck.

What bearings are in a rear differential?

Front and Rear Pinion Bearings & Carrier Bearings Pinion bearings are designed to reduce friction in the direction of desirable movement, increasing efficiency. In drive differentials, pinion bearings help the smallest gears in the differential work smoothly.
