Quality Standards for a Reliable Rear Axle

When you buy used drivetrain parts online, internal condition is everything. Here are the quality standards included with every Falcon Car Parts axle:

  • 1. Gear Tooth Inspection: We remove the cover to visually inspect for chipped or pitted teeth on the ring and pinion.
  • 2. Pinion Play Check: The pinion flange is checked to ensure there is no lateral play, indicating healthy bearings.
  • 3. Straightness Verification: We ensure the axle tubes are straight and the housing isn't bent from collision or overload.
  • 4. Limited-Slip Verification: If the unit is a Posi or Locker, we verify the internal clutch or locking mechanism functionality.
  • 5. ABS Sensor Port Check: We ensure the wheel speed sensor ports are clean and the tone rings are undamaged.
  • 6. Direct VIN Matching: We verify your ratio (e.g., 3.73, 4.10) to guarantee your vehicle's performance and speedometer accuracy.

Common Questions About Buying Used Rear Axles

The cost of a used rear axle typically ranges from $300 to $1,200+. Prices vary depending on the vehicle type (truck vs. sedan), gear ratio, and whether it is a limited-slip or locking differential. Heavy-duty truck axles like the Ford 10.5 or RAM 11.5 command higher prices.

Yes. Buying a used OEM rear axle is often safer than a cheap rebuild. We inspect internal gear teeth for chipping and backlash. As long as the housing is straight and the gears are quiet during spin-testing, a used OEM unit is highly reliable.

The most common signs are a high-pitched whining noise that changes with speed, a deep 'clunk' when shifting into gear, or heavy vibration from the rear end. Visible oil leaks around the pinion seal or cover are also warning signs.

Yes, it is critical. If your vehicle is 4WD or AWD, the rear axle gear ratio must match the front exactly. If it's a RWD vehicle, the wrong ratio will cause your speedometer to be incorrect and can lead to transmission shift issues. We match your VIN to guarantee the correct ratio.

For most rear-wheel-drive trucks and SUVs, it is much faster and more cost-effective to replace the complete 'assembly' (housing, shafts, and gears) rather than paying a shop to rebuild internal gears.

No. For shipping safety and environmental regulations, all units are drained of fluid. You must add fresh gear oil (and limited-slip additive if required) before operating the vehicle.

An LSD or locker allows both rear wheels to gain traction simultaneously in slippery conditions. Open differentials only send power to the wheel with the least resistance. We can use your VIN to determine which type your vehicle was factory-equipped with.

Generally, no. Used rear axle assemblies include the housing, internal gears, and axle shafts. Wearable brake parts like calipers, rotors, and pads are typically removed and should be replaced with new components during installation.

You can find your gear ratio by checking the metal identification tag attached to the differential cover bolts, or by looking up the RPO codes in your glovebox (for GM vehicles) or door sticker. Providing us with your VIN is the easiest way to guarantee an exact match.

Yes, all our tested used rear axle assemblies include a standard parts warranty. We inspect them rigorously for straightness and internal gear health, giving you complete peace of mind.
