Buying new means a dealer markup and a wait that can stretch into weeks. We take a different route: every used axle assembly for sale in our inventory comes from a low-mileage donor vehicle, passes a multi-point inspection, and gets confirmed against your specific ride before it leaves our facility. What you get is the same OEM part your vehicle came with, not a guess.
Beyond complete axle assemblies, our inventory includes fully inspected transfer cases, differentials, and transmissions to help you complete your drivetrain repair with confidence.
Rear End vs. Differential: Get to Know the Real Difference
Buyers use "rear end", "rear axle assembly", and "differential" interchangeably, but they aren't the same, and ordering the wrong one is the most common mistake.
Rear axle assembly
The complete unit, meaning the housing, the differential with its ring-and-pinion gears, and the axle shafts.
Differential
Just the geared center section inside the housing.
The complete assembly is the most common replacement we ship, and buying it whole is usually cheaper than rebuilding your original, provided it arrives as one OEM unit and not a box of mixed parts.
Dana 44 and Dana 60
The 44 is a lighter-duty axle found in trucks, Jeeps, and SUVs; the 60 is a heavy-duty unit used in 3/4-ton and 1-ton trucks.
GM 8.5
General Motors' 8.5-inch ring gear axle, common in half-ton and 3/4-ton trucks and SUVs.
Ford 9.75
Ford's 9.75-inch ring gear axle, used in later-model F-150s.
Chrysler 8.25
Found in Ram trucks, Dakotas, and Jeep Grand Cherokees.
AAM 9.25
Built by American Axle & Manufacturing for GM and Ram heavy-duty trucks.
Every rear-end must match your gear ratio (3.42, 3.73, 4.10, and others) and differential type: open, limited-slip (posi/Positraction), or locker, both confirmed against your VIN. An axle with the wrong ratio will run, but it won't drive right, and it won't pair correctly with the front axle on a 4x4.
Front Axle Assemblies Differ by Drivetrain
Trucks and 4x4s
F-150 and Super Duty, Silverado, Ram, Jeep Wrangler — the front axle houses its own differential with CV or U-joint shafts.
Front-wheel-drive cars
The equivalent parts are the CV axle shafts and the transaxle differential.
Tell us your year, make, model, and drivetrain (2WD, 4WD, or AWD) and we'll confirm the right front-axle configuration.
How to Identify Your Axle
Not sure which axle you have? Most factory axles carry a metal tag on the differential cover, or a stamp on the axle tube:
Gear ratio
A reading like "3 73" means a 3.73 ratio.
Limited-slip marking
An "L" in the number (e.g. "3 L 73") signals a limited-slip (posi) unit.
Dana axles
The BOM number identifies the model, ratio, and differential type in one code.
Can't find the tag? Your 17-digit VIN gives us the same information.
The wrong gear ratio is the single most common fitment mistake, so matching is where we focus. Your 17-digit VIN identifies your axle code and gear ratio, and we confirm several specs on top of that:
Differential type
open, limited-slip, or locking.
Spline count
so the axle shafts match your application.
ABS tone-ring spec
for correct wheel-speed readings.
Flange compatibility
so it bolts up to your driveshaft and hubs.
Why the Wrong Axle Costs More Than the Part
A mismatched axle causes problems well beyond the part itself, often within days:
ABS and traction-control faults — the ABS module reads the wheel-speed sensors against the axle's tone ring, so a wrong gear ratio, spline count, or tone-ring setup trips warning lights.
Hidden drivetrain wear — a wrong ratio quietly stresses your transfer case, CV joints, and differential, turning into a bigger bill later.
We Inspect Every Axle Before It Ships
Every axle passes a multi-point inspection before it's approved for sale:
Gear-ratio verification
Matches your vehicle's original spec.
Spline count check
Axle-shaft splines match your application.
Differential & carrier
Ring-and-pinion and carrier checked for wear or play.
Bearings & seals
Inspected for wear or leaks.
ABS tone ring
Tone ring and sensor port confirmed for proper ABS function.
Housing & tubes
Checked for cracks, bends, or damage.
Spin & noise test
Rotated to check for grinding, whine, or binding.

Factors That Affect the Price of a Used Axle
Make/model/year, gear ratio and differential type, donor mileage, and axle family (heavier axles cost more). Your VIN pins down the exact unit instead of a wide range.
Your 90-Day Warranty Coverage
Every qualifying unit (passed inspection, installed per instructions, unmodified from factory spec) includes a 90-day parts warranty covering gears and bearings in good condition. Gear oil must be added before operation to maintain coverage.
Covered:
parts only, no labor.
Installation
DIY won't void it, but damage from improper installation isn't covered.
Core Charge
None
Claims
Require a diagnostic report, installation report, and photo/video.
