Used Differential Assembly

       Differential Assembly has a significant impact on how your vehicle turns. The differential, as part of the front and back pivot assembly, plays an important role in how your vehicle turns.

What is Differential Assembly?

       A differential assembly is a component of the front or rear axle assembly. The axle is the central shaft around which the vehicle’s wheels rotate. The image below shows it on a vehicle with a four-wheel drive automatic Differential Assembly. The differential allows different speeds to be achieved by wheels on the same axle.

       Differentials have a long history, some say dating back to the first millennium BC and being recorded by China. While there were no cars back then, chariots, wagons, and carts still experienced wheel slipping and dragging when cornering, causing damage to wheels, axles, and roads. A simple differential was invented to avoid this.

       Later Pequeur of France (1827) invented the modern-day differential. This helped to rotate the wheels at different speeds while keeping both wheels powered.

How does it Work?

       As part of the axle assembly, all vehicles have either a front or rear differential. A front differential is present in a front-wheel-drive vehicle, whereas a rear differential is present in a rear-wheel-drive vehicle.

       If the vehicle is four-wheel or all-wheel drive, it may have both front and rear differentials. A differential is a gearbox with three common components: a side gear, a ring gear, and a pinion gear. Its function is to drive two wheels on an axle while allowing them to rotate at different speeds.

       This is required when your vehicle is turning on the road. As you go around a turn, the outside wheel must cover a greater distance than the inside wheel, so it must spin faster. This is made possible by the differential.

Differential Assembly Function:

  • Reduces the rotation coming from the gearbox before it is transferred to the rear axles.
  • Redirects the power’s axis of spin by 90 degrees.
  • When the farm vehicle is moving straight ahead, power should be distributed equally to both back-driving axles.
  • Divides the power based on the necessity of the driving axles during turning.

Brand New Differential and Used Differential:

       You expect a smooth ride when you get behind the wheel of your car. Without a differential, however, the wheels would spin and lose traction, especially when turning. That is why you should be aware of the symptoms of a bad differential as well as its primary function.

When to change the Differential Assembly?

  • Differential is Leaking Fluid
  • Emits an Unusual Odor and smoke
  • Causes Rough Idling
  • Works poorly
  • Vehicle Accelerates and disturbs wheel movement

Types of Differential Used in Automobiles:

  • Open Differential Assembly: This is most common in family sedans and economy vehicles. It divides engine torque into two energy outputs, allowing the wheels to spin at different speeds. This helps when one tire loses traction, another loses power to maintain traction.
    • Benefits:
      • Minimum friction losses
      • Eliminating wheel slip
      • Higher energy efficiency
    • Used in Vehicles:
      • Passenger vehicles
      • Commercial vehicles
      • Off-highway vehicles
  • Locking Differential Assembly: This type also known as a welded differential, connects the wheels to maintain the spin, thus same speed. Full-size trucks and Jeep Wranglers are examples of vehicles that use this type.
    • Benefits:
      • Improved NVH characteristics
      • Improved traction & wheel spin
      • Improved torque steer
    • Used in Vehicles:
      • Passenger vehicles
      • Light commercial vehicles
      • Hybrid/electric vehicles
  • Limited-Slip differential Assembly: This one provides the best of both worlds by operating as an open differential until slippage occurs, at which point the differential will automatically lock. Vehicles such as the Nissan 370Z and the Mazda MX-5 Miata use this differential assembly.
    • Benefits:
      • Allows more power without breaking traction
      • Maximizing traction & minimizing wheel spin
      • Eliminating torque steer
    • Used in Vehicles:
      • Off-road vehicles
      • Off-highway vehicles
      • Racing cars
  • Torque-Vectoring Assembly: The torque-vectoring differential, which is used by the BMW X5 M and Lexus RC F, uses additional gear trains to send a specific amount of torque to each wheel for added control in turns.
    • Benefits:
      • Improved NVH characteristics
      • Light-weight configuration
      • Flexibility for Manufacturing
    • Used in Vehicles:
      • Passenger vehicles
      • Light commercial vehicles
      • Hybrid/electric vehicle

Symptoms of Bad Differential:

  • Whining Sound: A whining sound is the most common symptom of a faulty differential. In many cases, this simply means that the differential components are not lubricated properly.
  • Damaged Tire: When both sides of your tires must travel at the same speed while cornering, your car’s inner tires will wear out faster because they are rotating faster than necessary.
  • Poor Handling: A properly functioning differential ensures that your vehicle corners as intended. If it fails, it will affect the cornering ability and create an unstable drive.
  • Frequent Vibration: When the differential or universal joints wear out, you will notice some vibration from the driveshaft. The vibrations will worsen as you step on the accelerator.

Reasons behind Faulty Differential and Durability:

    Age is one of the most common causes of a differential going bad. Internals will wear down and eventually fail as a result of differential aging. This can cause issues with the gears and bearings, resulting in costly repairs. It will wear down faster if the differential fluid is not changed regularly or if you drive around with a low differential fluid level.

    The differential is usually found at the back of your vehicle, underneath it. It must be kept lubricated with differential or gear oil for it to function properly and your vehicle to travel smoothly. Unless your owner’s manual specifies otherwise, the oil should be changed every 30,000 to 50,000 miles.

Replacing Faulty Differential and Cost:

    Complete rear differential assembly costs around $1000 and $4000 to replace. Fortunately, you can simply replace it with a used differential, significantly lowering your costs with 50 States Auto Parts.

    Even if you prefer repairing the differential, it will cost between $200 and $400 to complete. Repairing costs depend on the severity of the defect and the components that must be replaced.
