Used Ford 8.8 Rear End for Sale — VIN-Verified.
Used & remanufactured differentials and rear axle assemblies — VIN-verified for the correct gear ratio, tested, and shipped from Pasadena. 0% restocking, ever.
Used & remanufactured Ford 8.8 Rear End — VIN-verified, tested, and shipped nationwide from our Pasadena, TX facility. Fits F-150, Mustang, Explorer, Ranger.
The Ford 8.8 is one of the most-searched used differentials in the country. We VIN-match the exact gear ratio (3.31, 3.55, 3.73, 4.10), open vs limited-slip, and axle width. Ultra Auto Parts TX is Houston's drivetrain specialist, and differentials and rear axle assemblies are squarely in our wheelhouse. From our shop at 5041 Spencer Hwy in Pasadena, we stock and source used and remanufactured differentials for trucks, SUVs and cars across the Houston metro — Ford 8.8 and 9.75, GM 10-bolt and 14-bolt, Dana 44 and Dana 60, Chrysler 9.25 and Toyota 8-inch. Every axle gets verified against your VIN and axle tag before it leaves. Drivetrain is our specialty, not a sideline — while general salvage yards sell whatever rolls in, we test differentials on backlash gauges and gear-pattern analyzers and match them to your exact gear ratio and traction setup. Whether you need a complete third member, a full-float rear axle assembly, or a limited-slip carrier, our bilingual (English/Spanish) team helps Houston, Pasadena, Deer Park and Pearland drivers get the right part the first time.
Known issues we check on the Ford 8.8 Rear End
The Ford 8.8 is tough, but we inspect the known wear: the Traction-Lok clutch pack that wears out (one-wheel spin), spider/pinion gears and the cross pin, plus bearing whine and axle-tube seal leaks. We VIN-match the exact gear ratio (3.31, 3.55, 3.73, 4.10), open vs limited-slip, and 28- vs 31-spline axle, then measure backlash and gear pattern before it ships. Getting the ratio right matters — a mismatch throws off your speedometer and ABS.
Used vs. remanufactured Ford 8.8 Rear End — which to buy
A tested used 8.8 is a strong value when the ring-and-pinion and clutches check out, and ours are measured for backlash and pattern first. Remanufactured or a fresh carrier setup makes sense if you want new bearings and a fresh limited-slip with a longer warranty. We match ratio, spline, and carrier type to your VIN. Send your VIN and we tell you honestly which fits your F-150, Mustang, or Explorer.
Ford 8.8 specs & applications we source
The Ford 8.8 measures 8.8 inches across the ring gear and comes in both a truck version (F-150, Explorer, Ranger) and an IRS/independent version (2015+ Mustang, older Thunderbird/Cougar) that are NOT interchangeable. Axle-tube width, bolt pattern, and brake flange differ by application, so a Mustang 8.8 will not bolt under an F-150. We stock 28-spline (car/light) and 31-spline (truck/HD) carriers and confirm the width and ABS tone-ring type by VIN so the swap is truly drop-in.
Why buy a quality used differentials?
A used or remanufactured differential is a fraction of new or dealer cost, and a complete used rear axle assembly often drops in with housing, carrier, gears and axle shafts already matched. Low-mileage salvage units from the same year/make/model carry the correct ratio and spline count, so you avoid guessing. Reman is built to OEM spec with new bearings and a fresh gear set for longer life and a stronger warranty.
Common signs you need a replacement
Failing differentials give warning signs: howling or whining that changes with speed (worn ring-and-pinion or bad bearings), a clunk on acceleration (worn spider/side gears or excess backlash), metal-flake in the fluid, and chatter on turns from a tired limited-slip. Ignored, spider gear failure or a spun bearing can lock or destroy the axle — replacing the unit is often smarter than a partial fix.

Fitment Flags We Check
- Gear ratio MUST match the other axle (and speedometer/PCM) — 3.42 vs 3.73 will not mix on 4WD
- Open vs. limited-slip vs. locker changes the carrier and behavior — confirm what you have
- ABS/traction tone (reluctor) ring tooth count must match your sensor
- Axle width, spline count and flange/bolt pattern vary within the same axle family
- Drum vs. disc rear brakes affect the axle ends and backing plates
- Verify with VIN plus the axle tag / door-jamb RPO or axle code — not just year/make/model
Heavy-duty axles for diesel and tow rigs — Dana 60/70, GM 10.5 14-bolt full-float, and AAM 11.5 out of F-250/350, 2500/3500 and Ram HD trucks — are available and matched to your GVWR and ratio.
What to send for an exact quote
- VIN (best — locks ratio, traction type and spline)
- Year / make / model / trim
- Gear ratio (from the axle tag or door-jamb RPO)
- Open or limited-slip / locker
- Front or rear, and 2WD or 4WD
