Quality Used Carrier Assemblies You Can Trust

The differential assembly is responsible for transferring engine torque to your wheels while allowing them to turn at different speeds during a corner. At Falcon Car Parts, we specialize in providing genuine used differentials that offer the durability of factory engineering without the extreme cost of a new carrier.

Every used differential in our inventory undergoes a rigorous inspection. We check the backlash between the ring and pinion, inspect carrier bearings for noise, and verify that the housing is free of cracks or impact damage.

  • Smooth Rotation: Bench-tested to ensure zero grinding or hesitation.
  • OEM Specs: Proper casting and internal components for your specific VIN.
  • Sealed Integrity: Mounting surfaces and pinion areas checked for leaks.

Our 6-Point Quality Check for Differentials

Drivetrain reliability is our priority. Every used differential sold by Falcon Car Parts passes the following standards:

  • 1. Ratio Verification: We manually count the ring and pinion teeth to verify the gear ratio matches your factory specs.
  • 2. Backlash Inspection: We measure the play between the gears to ensure it falls within OEM tolerances.
  • 3. Gear Tooth Check: A visual scan for pitting, chipping, or "bluing" from extreme heat.
  • 4. Pinion Bearing Audit: The pinion shaft is checked for side-play and rotated to ensure silence.
  • 5. Case Integrity: The casting is checked for cracks, especially around the mounting ears and carrier bearing caps.
  • 6. Internal Cleaning: The unit is flushed of old oil and any residue to provide a clean start for your new fluid.

Common Questions About Buying Used Differentials

Used OEM differential assemblies typically cost between $250 and $850. Prices vary based on whether it is a standard open differential, an LSD, or an electronic locker.

Common signs include a high-pitched whining noise while accelerating, clunking during gear shifts, or heavy vibrations.

Yes, provided it is bench-tested. We rotate the input shaft to check for smooth gear mesh and inspect the ring and pinion teeth for wear.

The ratio is usually found on a metal tag attached to the differential cover or via your VIN. It is crucial to match the ratio exactly.

An open differential sends power to the wheel with the least resistance, while an LSD uses gears to distribute torque for better traction.

No. All units are drained for safe shipping. You must fill the differential with the manufacturer's recommended gear oil before driving.

Buying a complete used OEM assembly is a 'drop-in' solution that avoids the precision gear setup and expensive labor required for a rebuild.

We inspect all external seals for active leaks. We recommend installing new seals during the swap as a preventative measure.

A differential assembly generally includes the center carrier and housing. Axle shafts are typically sold separately.
